Measurement Channels<\/h2>\n<p>The <strong>Fluke Calibration 1529<\/strong> features four measurement channels.<\/p>\n<p>Depending on the selected model, the channels can be configured for different temperature sensor technologies.<\/p>\n<p>Three configurations are available.<\/p>\n<h3>Fluke Calibration 1529<\/h3>\n<p>The standard configuration provides:<\/p>\n<p><strong>Two PRT\/thermistor channels and two thermocouple channels.<\/strong><\/p>\n<p>This configuration is particularly useful when resistance thermometers and thermocouples must be measured within the same calibration system.<\/p>\n<h3>Fluke Calibration 1529-R<\/h3>\n<p>The 1529-R provides:<\/p>\n<p><strong>Four PRT\/thermistor channels.<\/strong><\/p>\n<p>This configuration is ideal for temperature calibration laboratories using precision resistance thermometers and thermistors.<\/p>\n<h3>Fluke Calibration 1529-T<\/h3>\n<p>The 1529-T provides:<\/p>\n<p><strong>Four thermocouple channels.<\/strong><\/p>\n<p>This configuration is particularly suitable for industrial thermocouple measurements and high-temperature calibration applications.<\/p>\n<p>The input configuration must be selected when ordering the instrument.<\/p>\n<h2>High-Precision Temperature Measurement<\/h2>\n<p>The Fluke Calibration 1529 is designed for demanding temperature measurement applications.<\/p>\n<p>Its precision measurement circuitry provides excellent accuracy for resistance thermometers, thermistors and thermocouples.<\/p>\n<p>The manufacturer specifies the following readout accuracies for selected measurement conditions:<\/p>\n<p><strong>PRT at 0 \u00b0C: \u00b10.006 \u00b0C<\/strong><\/p>\n<p><strong>Thermistor at 25 \u00b0C: \u00b10.0025 \u00b0C<\/strong><\/p>\n<p><strong>Type J thermocouple at 600 \u00b0C: \u00b10.35 \u00b0C with internal reference junction compensation<\/strong><\/p>\n<p>These values refer to the thermometer readout and do not include the measurement uncertainty of the connected temperature sensor.<\/p>\n<p>The total uncertainty of a complete temperature measurement system also depends on the sensor calibration, stability, self-heating and measurement conditions.<\/p>\n<p>This distinction is particularly important for accredited temperature calibration laboratories.<\/p>\n<h2>Platinum Resistance Thermometer Measurement<\/h2>\n<p>The Fluke Calibration 1529 supports precision platinum resistance thermometers.<\/p>\n<p>PRTs are widely used in temperature metrology because of their excellent stability and reproducibility.<\/p>\n<p>The instrument supports temperature measurements from:<\/p>\n<p><strong>\u2212189 \u00b0C to +960 \u00b0C<\/strong><\/p>\n<p>The resistance measurement range

data-spread=\"false\">\n<li>ITS-90<\/li>\n<li>IEC 751<\/li>\n<li>Callendar-Van Dusen<\/li>\n<\/ul>\n<p>These methods allow the measured resistance to be converted into temperature according to the selected sensor characteristic.<\/p>\n<p>The ITS-90 conversion is particularly useful for calibrated reference thermometers.<\/p>\n<h2>PRT Measurement Accuracy<\/h2>\n<p>The Fluke Calibration 1529 provides excellent readout accuracy for platinum resistance thermometers.<\/p>\n<p>Typical manufacturer specifications include:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Temperature<\/th>\n<th>PRT Readout

defined conditions.<\/p>\n<p>The actual measurement uncertainty depends on the connected PRT and its calibration.<\/p>\n<h2>Precision Thermistor Measurement<\/h2>\n<p>The <strong>Fluke Calibration 1529<\/strong> also supports precision thermistors.<\/p>\n<p>Thermistors are temperature-dependent resistors that provide excellent sensitivity over relatively limited temperature ranges.<\/p>\n<p>The supported temperature range is:<\/p>\n<p><strong>\u221250 \u00b0C to +150 \u00b0C<\/strong><\/p>\n<p>The resistance measurement range extends to:<\/p>\n<p><strong>500 k\u03a9<\/strong><\/p>\n<p>The manufacturer specifies a readout accuracy of:<\/p>\n<p><strong>\u00b10.0025 \u00b0C at 25 \u00b0C<\/strong><\/p>\n<p>The instrument supports Steinhart-Hart temperature conversion and the YSI-400 characteristic.<\/p>\n<p>This allows different precision thermistor types to be used.<\/p>\n<h2>Thermistor Measurement Accuracy<\/h2>\n<p>The Fluke Calibration 1529 provides excellent accuracy when measuring precision thermistors.<\/p>\n<p>Typical manufacturer specifications include:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Temperature<\/th>\n<th>Thermistor Readout Accuracy<\/th>\n<\/tr>\n<tr>\n<td>0

demonstrate the excellent measurement performance available with precision thermistors.<\/p>\n<p>Thermistors are particularly suitable for accurate reference temperature measurements near room temperature.<\/p>\n<h2>Steinhart-Hart Temperature Conversion<\/h2>\n<p>The Fluke Calibration 1529 supports the Steinhart-Hart equation.<\/p>\n<p>This equation describes the nonlinear relationship between thermistor resistance and temperature.<\/p>\n<p>A common form is:<\/p>\n<p><strong>1\/T = A + B \u00d7 ln(R) + C \u00d7 [ln(R)]\u00b3<\/strong><\/p>\n<p>Where:<\/p>\n<ul data-spread=\"false\">\n<li>T = Absolute temperature in kelvin<\/li>\n<li>R = Thermistor resistance<\/li>\n<li>A, B and C = Sensor-specific coefficients<\/li>\n<\/ul>\n<p>The coefficients are determined during sensor calibration.<\/p>\n<p>By entering the appropriate coefficients, the Fluke Calibration 1529 can calculate temperature according to the characteristics of the connected thermistor.<\/p>\n<p>This improves measurement accuracy compared with using a generic sensor characteristic.<\/p>\n<h2>Thermocouple Temperature Measurement<\/h2>\n<p>The Fluke Calibration 1529 supports several thermocouple types.<\/p>\n<p>Standard supported types include:<\/p>\n<ul data-spread=\"false\">\n<li>Type B<\/li>\n<li>Type E<\/li>\n<li>Type J<\/li>\n<li>Type K<\/li>\n<li>Type N<\/li>\n<li>Type R<\/li>\n<li>Type S<\/li>\n<li>Type T<\/li>\n<li>Au-Pt thermocouples<\/li>\n<\/ul>\n<p>Additional thermocouple characteristics, including types C and U, can be supported using appropriate configurations.<\/p>\n<p>The thermocouple measurement range extends from:<\/p>\n<p><strong>\u2212270 \u00b0C to +1800 \u00b0C<\/strong><\/p>\n<p>The actual temperature range depends on the selected thermocouple type.<\/p>\n<p>The instrument measures the thermoelectric voltage and converts it into temperature according to the selected characteristic.<\/p>\n<h2>Internal and External Reference Junction Compensation<\/h2>\n<p>Accurate thermocouple measurements require consideration of the reference junction temperature.<\/p>\n<p>The Fluke Calibration 1529 supports:<\/p>\n<p><strong>Internal reference junction compensation<\/strong><\/p>\n<p>and<\/p>\n<p><strong>External reference junction compensation<\/strong><\/p>\n<p>Internal compensation uses the instrument&#8217;s reference junction temperature measurement.<\/p>\n<p>External compensation allows a separately established reference junction temperature to be used.<\/p>\n<p>This provides additional flexibility for laboratory thermocouple measurements.<\/p>\n<p>The manufacturer specifies an internal reference junction contribution of approximately:<\/p>\n<p><strong>\u00b10.25 \u00b0C<\/strong><\/p>\n<p>The choice of reference junction compensation method influences the achievable measurement accuracy.<\/p>\n<h2>High-Accuracy Resistance Measurement<\/h2>\n<p>The Fluke Calibration 1529 provides precision resistance measurement for PRTs, RTDs and thermistors.<\/p>\n<p>For PRT measurements, the manufacturer specifies:<\/p>\n<p><strong>0 \u03a9 to 20 \u03a9: \u00b10.0005 \u03a9<\/strong><\/p>\n<p><strong>20 \u03a9 to 400 \u03a9: \u00b125 ppm of reading<\/strong><\/p>\n<p>For thermistors, the specified resistance measurement ranges include:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Resistance Range<\/th>\n<th>Accuracy<\/th>\n<\/tr>\n<tr>\n<td>0 \u03a9 to 5 k\u03a9<\/td>\n<td>\u00b10.5 \u03a9<\/td>\n<\/tr>\n<tr>\n<td>5 k\u03a9 to 200

describe the measurement accuracy of the instrument.<\/p>\n<p>The corresponding temperature accuracy depends on the resistance-temperature characteristic of the connected sensor.<\/p>\n<h2>Four-Wire Resistance Measurement<\/h2>\n<p>The Fluke Calibration 1529 supports two-, three- and four-wire connections for resistance-based temperature sensors.<\/p>\n<p>Four-wire measurement is particularly useful for precision temperature metrology.<\/p>\n<p>In a four-wire configuration, the current-carrying and voltage-sensing connections are separated.<\/p>\n<p>This minimizes the influence of connecting lead resistance.<\/p>\n<p>Four-wire measurement is therefore preferred for high-accuracy reference temperature measurements.<\/p>\n<p>The Fluke Calibration 1529 uses a reversing excitation current of:<\/p>\n<p><strong>1 mA for PRT measurements<\/strong><\/p>\n<p>This helps reduce the influence of thermoelectric offset voltages.<\/p>\n<h2>Integrated Data Logger<\/h2>\n<p>The <strong>Fluke Calibration 1529<\/strong> includes an integrated data logger.<\/p>\n<p>The instrument can store up to:<\/p>\n<p><strong>8,000 measurements<\/strong><\/p>\n<p>Recorded measurements include date and time information.<\/p>\n<p>This makes the instrument suitable for temperature stability monitoring and laboratory measurement documentation.<\/p>\n<p>The instrument also supports storage of:<\/p>\n<p><strong>100 individual measurements<\/strong><\/p>\n<p>Measurement data can be organized into logging sessions.<\/p>\n<p>Each session can be assigned an identifying label.<\/p>\n<p>This simplifies the organization and evaluation of recorded temperature measurements.<\/p>\n<h2>Fourteen Selectable Logging Intervals<\/h2>\n<p>The Fluke Calibration 1529 supports fourteen selectable logging intervals.<\/p>\n<p>Available intervals include:<\/p>\n<ul data-spread=\"false\">\n<li>0.1 seconds<\/li>\n<li>0.2 seconds<\/li>\n<li>0.5 seconds<\/li>\n<li>1 second<\/li>\n<li>2 seconds<\/li>\n<li>5 seconds<\/li>\n<li>10 seconds<\/li>\n<li>30 seconds<\/li>\n<li>60 seconds<\/li>\n<li>2 minutes<\/li>\n<li>5 minutes<\/li>\n<li>10 minutes<\/li>\n<li>30 minutes<\/li>\n<li>60 minutes<\/li>\n<\/ul>\n<p>This flexibility allows the instrument to be adapted to different measurement applications.<\/p>\n<p>Short intervals are suitable for monitoring rapid temperature changes.<\/p>\n<p>Longer intervals are useful for extended temperature stability measurements.<\/p>\n<h2>Fast Measurement Mode<\/h2>\n<p>The Fluke Calibration 1529 provides a fast measurement mode.<\/p>\n<p>The manufacturer specifies measurement rates of up to:<\/p>\n<p><strong>10 readings per second<\/strong><\/p>\n<p>This mode is available for measurements on one channel.<\/p>\n<p>For simultaneous measurements of multiple channels, measurement intervals of one second or longer are supported.<\/p>\n<p>Fast measurement mode is particularly useful when observing relatively rapid temperature changes.<\/p>\n<p>For high-accuracy measurements, the influence of operating conditions and measurement speed must be considered.<\/p>\n<h2>Simultaneous Temperature Comparison<\/h2>\n<p>The four-channel design makes the Fluke Calibration 1529 particularly useful for temperature comparison measurements.<\/p>\n<p>For example, one channel can be connected to a calibrated reference thermometer.<\/p>\n<p>The remaining channels can be connected to temperature sensors under test.<\/p>\n<p>All sensors can be placed in the same temperature source.<\/p>\n<p>The difference between the indication of a device under test and the reference temperature can be calculated as:<\/p>\n<p><strong>\u0394T = T_DUT \u2212 T_REF<\/strong><\/p>\n<p>Where:<\/p>\n<ul data-spread=\"false\">\n<li>\u0394T = Temperature indication difference<\/li>\n<li>T_DUT = Temperature indicated by the device under test<\/li>\n<li>T_REF = Reference temperature<\/li>\n<\/ul>\n<p>This method is commonly used for temperature comparison calibration.<\/p>\n<p>The overall measurement uncertainty must consider the reference thermometer, temperature source, immersion conditions and other relevant contributions.<\/p>\n<h2>Temperature Calibration Baths<\/h2>\n<p>The Fluke Calibration 1529 is particularly suitable for use with liquid calibration baths.<\/p>\n<p>A calibrated reference thermometer can be connected to one channel.<\/p>\n<p>Additional temperature sensors can be connected to the remaining channels.<\/p>\n<p>All sensors are immersed in the calibration bath.<\/p>\n<p>The thermometer readout measures the temperatures simultaneously.<\/p>\n<p>This allows several temperature sensors to be compared with the reference thermometer.<\/p>\n<p>The integrated data logger can also record temperature changes during the calibration procedure.<\/p>\n<h2>Dry-Block Temperature Calibration<\/h2>\n<p>The Fluke Calibration 1529 can also be used with dry-block temperature calibrators.<\/p>\n<p>A calibrated reference temperature probe is inserted into a suitable calibration insert.<\/p>\n<p>Additional temperature sensors can be measured using the remaining channels.<\/p>\n<p>This allows several sensors to be evaluated during the same calibration procedure.<\/p>\n<p>The Fluke Calibration 1529 measures temperature but does not generate a physical temperature.<\/p>\n<h2>Graphical Display<\/h2>\n<p>The Fluke Calibration 1529 features an illuminated graphical LCD.<\/p>\n<p>The manufacturer specifies a display size of:<\/p>\n<p><strong>33 \u00d7 127 mm<\/strong><\/p>\n<p>The display allows users to view temperature measurements and additional measurement parameters.<\/p>\n<p>Up to eight user-selected data fields can be displayed.<\/p>\n<p>This provides a convenient overview of multiple measurement channels.<\/p>\n<p>Supported display units include:<\/p>\n<ul data-spread=\"false\">\n<li>\u00b0C<\/li>\n<li>\u00b0F<\/li>\n<li>K<\/li>\n<li>\u03a9<\/li>\n<li>k\u03a9<\/li>\n<li>mV<\/li>\n<\/ul>\n<h2>Measurement Averaging<\/h2>\n<p>The Fluke Calibration 1529 provides configurable measurement averaging.<\/p>\n<p>The instrument can calculate a moving average of the most recent:<\/p>\n<p><strong>2 to 10 readings<\/strong><\/p>\n<p>The number of readings can be selected by the user.<\/p>\n<p>Measurement averaging can reduce the influence of random fluctuations in the displayed measurement values.<\/p>\n<p>This is particularly useful when monitoring stable temperature conditions.<\/p>\n<h2>RS-232 Communication<\/h2>\n<p>The Fluke Calibration 1529 includes an RS-232 communication interface.<\/p>\n<p>The interface allows the instrument to communicate with a computer or automated calibration system.<\/p>\n<p>Measurement data can be transferred for analysis and documentation.<\/p>\n<p>Remote control functions allow the thermometer readout to be integrated into computer-controlled measurement applications.<\/p>\n<h2>Optional IEEE-488 Interface<\/h2>\n<p>An optional IEEE-488 interface is available for the Fluke Calibration 1529.<\/p>\n<p>IEEE-488, also known as GPIB, is widely used in automated laboratory measurement systems.<\/p>\n<p>The interface allows the thermometer readout to be integrated into computer-controlled calibration systems.<\/p>\n<p>This is particularly useful when several measurement instruments must be controlled through a central computer.<\/p>\n<h2>Fluke LogWare II Software<\/h2>\n<p>The Fluke Calibration 1529 is compatible with Fluke LogWare II software.<\/p>\n<p>LogWare II supports computer-based temperature monitoring and data acquisition.<\/p>\n<p>The software can record measurements from all four channels.<\/p>\n<p>Typical functions include:<\/p>\n<ul data-spread=\"false\">\n<li>Temperature data acquisition<\/li>\n<li>Measurement logging<\/li>\n<li>Graphical temperature trends<\/li>\n<li>Statistical evaluation<\/li>\n<li>Alarm functions<\/li>\n<li>Automated measurement recording<\/li>\n<li>Measurement documentation<\/li>\n<\/ul>\n<p>When measurements are recorded directly to a computer, the amount of stored data is not restricted to the instrument&#8217;s internal memory capacity.<\/p>\n<h2>MET\/TEMP II Calibration Software<\/h2>\n<p>The Fluke Calibration 1529 is also compatible with MET\/TEMP II temperature calibration software.<\/p>\n<p>MET\/TEMP II supports automated temperature calibration procedures.<\/p>\n<p>The software allows compatible reference thermometers and temperature sources to be integrated into a calibration system.<\/p>\n<p>With the Fluke Calibration 1529, one channel can be used for a reference thermometer while up to three additional channels measure sensors under test.<\/p>\n<p>This provides an efficient solution for automated temperature comparison calibration.<\/p>\n<h2>Rechargeable Battery Operation<\/h2>\n<p>The Fluke Calibration 1529 includes a rechargeable NiMH battery.<\/p>\n<p>The manufacturer specifies a typical battery operating time of:<\/p>\n<p><strong>8 hours<\/strong><\/p>\n<p>This value applies to

hours<\/strong><\/p>\n<p>Battery operation makes the instrument suitable for mobile calibration applications.<\/p>\n<h2>Compact Laboratory Design<\/h2>\n<p>The Fluke Calibration 1529 combines laboratory measurement performance with a relatively compact design.<\/p>\n<p>The manufacturer specifies the following dimensions:<\/p>\n<p><strong>102 \u00d7 191 \u00d7 208 mm<\/strong><\/p>\n<p>The weight is approximately:<\/p>\n<p><strong>2 kg<\/strong><\/p>\n<p>The instrument can be used on laboratory benches or transported to different measurement locations.<\/p>\n<p>An optional carrying case is available for additional protection during transport.<\/p>\n<h2>Technical Highlights<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Feature<\/th>\n<th>Fluke Calibration 1529<\/th>\n<\/tr>\n<tr>\n<td>Product
