transmitters<\/li>\n<\/ul>\n<h2>Noncontact Measurement of 4 to 20 mA Signals<\/h2>\n<p>The most important feature of the <strong>Fluke Calibration 773<\/strong> is its ability to measure current signals without disconnecting the electrical circuit.<\/p>\n<p>Conventional current measurements normally require the circuit to be opened so that the measuring instrument can be connected in series.<\/p>\n<p>This procedure can interrupt the process signal and potentially affect the operation of industrial equipment.<\/p>\n<p>The Fluke Calibration 773 eliminates this requirement by using a highly sensitive current clamp.<\/p>\n<p>The clamp detects the magnetic field generated by the current flowing through the conductor.<\/p>\n<p>This allows technicians to measure the current while the process remains operational.<\/p>\n<p>Typical applications include checking transmitter outputs, monitoring control signals and troubleshooting industrial automation systems.<\/p>\n<p>The noncontact measurement method is particularly advantageous in production environments where interruptions must be minimized.<\/p>\n<h2>High Measurement Accuracy<\/h2>\n<p>The Fluke Calibration 773 provides accurate current measurements for industrial process applications.<\/p>\n<p>In its primary clamp measurement range, the manufacturer specifies an accuracy of:<\/p>\n<p><strong>\u00b1(0.2% of reading + 5 counts)<\/strong><\/p>\n<p>The instrument provides a resolution of:<\/p>\n<p><strong>0.01 mA<\/strong><\/p>\n<p>This allows small variations in process current to be detected.<\/p>\n<p>The instrument is particularly suitable for checking standardized 4 to 20 mA signals.<\/p>\n<p>For measurements above the primary clamp range, a separate accuracy specification applies.<\/p>\n<p>The accuracy specifications must always be considered together with the applicable measurement range and resolution.<\/p>\n<h2>Current Measurement up to 100 mA<\/h2>\n<p>The Fluke Calibration 773 provides two clamp measurement ranges.<\/p>\n<table>\n<tbody>\n<tr>\n<th>Measurement Range<\/th>\n<th>Accuracy<\/th>\n<\/tr>\n<tr>\n<td>0 to 20.99 mA<\/td>\n<td>\u00b1(0.2% of reading + 5 counts)<\/td>\n<\/tr>\n<tr>\n<td>21.0 to 100.0 mA<\/td>\n<td>\u00b1(1% of reading + 5 counts)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The extended measurement range makes the instrument suitable for checking older industrial control systems using current signals above 20 mA.<\/p>\n<p>This includes applications with 10 to 50 mA signals.<\/p>\n<p>The instrument can therefore be used for both modern and legacy process instrumentation.<\/p>\n<h2>Current Measurement Using Test Leads<\/h2>\n<p>In addition to noncontact clamp measurements, the Fluke Calibration 773 supports conventional current measurement through its test terminals.<\/p>\n<p>The measurement range is:<\/p>\n<p><strong>0 to 24.00 mA<\/strong><\/p>\n<p>The specified accuracy is:<\/p>\n<p><strong>\u00b1(0.2% of reading + 2 counts)<\/strong><\/p>\n<p>This function is useful when a direct electrical connection is preferred or when a process current must be measured in series.<\/p>\n<p>It also allows the instrument to be used for comparison measurements between clamp and conventional current measurement methods.<\/p>\n<h2>Current Sourcing from 0 to 24 mA<\/h2>\n<p>The Fluke Calibration 773 can generate precise current signals for testing industrial process equipment.<\/p>\n<p>The current sourcing range is:<\/p>\n<p><strong>0 to 24.00 mA<\/strong><\/p>\n<p>The specified accuracy is:<\/p>\n<p><strong>\u00b1(0.2% of output + 2 counts)<\/strong><\/p>\n<p>The maximum output capability is 24 mA into a load of 1,000 \u03a9.<\/p>\n<p>This function is particularly useful for testing control system inputs.<\/p>\n<p>For example, a technician can generate a defined current signal and verify whether a programmable logic controller interprets the signal correctly.<\/p>\n<p>Current sourcing can also be used to test current to pressure converters and other industrial devices.<\/p>\n<h2>Current Simulation<\/h2>\n<p>The Fluke Calibration 773 supports current simulation.<\/p>\n<p>The simulation range is:<\/p>\n<p><strong>0 to 24.00 mA<\/strong><\/p>\n<p>The specified accuracy is:<\/p>\n<p><strong>\u00b1(0.2% of output + 2 counts)<\/strong><\/p>\n<p>In simulation mode, the instrument controls the current in a loop powered by an external supply.<\/p>\n<p>This differs from current sourcing, where the instrument actively provides the current.<\/p>\n<p>The simulation function is useful for testing transmitter inputs and control systems that provide their own loop power.<\/p>\n<p>The maximum external voltage for current simulation is 50 V DC.<\/p>\n<h2>Integrated 24 V Loop Power Supply<\/h2>\n<p>The Fluke Calibration 773 includes an integrated 24 V loop power supply.<\/p>\n<p>This allows technicians to power compatible two wire transmitters during testing.<\/p>\n<p>The instrument can simultaneously provide loop power and measure the current signal.<\/p>\n<p>This function is particularly useful when a transmitter must be tested outside its normal installation environment.<\/p>\n<p>For example, a pressure transmitter can be powered by the instrument while its output signal is monitored.<\/p>\n<p>The integrated loop supply reduces the need for additional external equipment.<\/p>\n<h2>DC Voltage Measurement<\/h2>\n<p>The Fluke Calibration 773 provides DC voltage measurement for industrial process applications.<\/p>\n<p>The measurement range is:<\/p>\n<p><strong>0 to 30.00 V DC<\/strong><\/p>\n<p>The specified accuracy is:<\/p>\n<p><strong>\u00b1(0.2% of reading + 2 counts)<\/strong><\/p>\n<p>This function is particularly useful for checking 24 V power supplies.<\/p>\n<p>It can also be used to measure voltage signals from programmable logic controllers and industrial transmitters.<\/p>\n<p>Voltage measurement expands the functionality of the instrument beyond conventional milliamp clamp meters.<\/p>\n<h2>DC Voltage Sourcing<\/h2>\n<p>The Fluke Calibration 773 can generate DC voltage signals.<\/p>\n<p>The voltage sourcing range is:<\/p>\n<p><strong>0 to 10.00 V DC<\/strong><\/p>\n<p>The specified accuracy is:<\/p>\n<p><strong>\u00b1(0.2% of output + 2 counts)<\/strong><\/p>\n<p>The maximum output current is 2 mA.<\/p>\n<p>This function is useful for testing devices that accept standardized voltage signals.<\/p>\n<p>Typical examples include:<\/p>\n<ul>\n<li>0 to 10 V control inputs<\/li>\n<li>1 to 5 V process signals<\/li>\n<li>PLC analog inputs<\/li>\n<li>Industrial control modules<\/li>\n<li>Signal converters<\/li>\n<\/ul>\n<p>The instrument allows technicians to verify whether the connected equipment responds correctly to the applied voltage.<\/p>\n<h2>Automatic Ramp and Step Functions<\/h2>\n<p>The Fluke Calibration 773 supports automatic current and voltage output functions.<\/p>\n<p>These functions simplify testing of industrial control systems.<\/p>\n<h3>Automatic Current Ramping<\/h3>\n<p>The instrument can automatically vary its current output.<\/p>\n<p>This allows the response of connected equipment to be checked over a defined signal range.<\/p>\n<p>Automatic ramping is particularly useful for testing analog inputs and control devices.<\/p>\n<h3>Automatic 25% Steps<\/h3>\n<p>The instrument can generate standardized output steps.<\/p>\n<p>For a 4 to 20 mA signal, typical test points are:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Output Percentage<\/th>\n<th>Current<\/th>\n<\/tr>\n<tr>\n<td>0%<\/td>\n<td>4 mA<\/td>\n<\/tr>\n<tr>\n<td>25%<\/td>\n<td>8 mA<\/td>\n<\/tr>\n<tr>\n<td>50%<\/td>\n<td>12 mA<\/td>\n<\/tr>\n<tr>\n<td>75%<\/td>\n<td>16 mA<\/td>\n<\/tr>\n<tr>\n<td>100%<\/td>\n<td>20 mA<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>These values allow technicians to verify the linearity and scaling of industrial measurement systems.<\/p>\n<p>Automatic stepping reduces manual adjustments and helps improve testing efficiency.<\/p>\n<h2>Simultaneous Current Measurement and Sourcing<\/h2>\n<p>The Fluke Calibration 773 provides a useful simultaneous measurement and sourcing function.<\/p>\n<p>The instrument can measure a current signal with its clamp while generating a separate current signal.<\/p>\n<p>This function is particularly useful for testing industrial devices with both analog inputs and outputs.<\/p>\n<p>For example, a control valve positioner can receive a defined input current while its feedback signal is measured.<\/p>\n<p>This allows technicians to evaluate the relationship between input and output signals.<\/p>\n<p>The function can also be used for checking signal isolators and other process control equipment.<\/p>\n<h2>Scaled Milliamp Output<\/h2>\n<p>The Fluke Calibration 773 includes a scaled milliamp output function.<\/p>\n<p>This function generates an output current corresponding to the current measured by the clamp.<\/p>\n<p>The scaled output can be connected to a compatible recording instrument.<\/p>\n<p>This allows process current signals to be monitored or recorded without disconnecting the original current loop.<\/p>\n<p>The function is particularly useful when troubleshooting intermittent process problems.<\/p>\n<p>A compatible data logging multimeter can record the scaled output over time.<\/p>\n<p>This provides additional information about signal variations during normal process operation.<\/p>\n<h2>Detachable Current Clamp<\/h2>\n<p>The Fluke Calibration 773 features a detachable current clamp.<\/p>\n<p>The clamp can be separated from the main instrument and connected through its cable.<\/p>\n<p>This allows current measurements to be performed in locations where access is restricted.<\/p>\n<p>Typical examples include densely populated control cabinets and industrial junction boxes.<\/p>\n<p>The detachable design improves handling and allows the display to remain visible while the clamp is positioned around the conductor.<\/p>\n<p>This is particularly useful during troubleshooting and maintenance work.<\/p>\n<h2>Calibration of Temperature Transmitters<\/h2>\n<p>The Fluke Calibration 773 is suitable for checking the electrical output signals of temperature transmitters.<\/p>\n<p>Temperature transmitters commonly convert RTD or thermocouple signals into standardized 4 to 20 mA outputs.<\/p>\n<p>The instrument can measure these signals without disconnecting the current loop.<\/p>\n<p>For example, a temperature transmitter with a measuring range from 0 \u00b0C to 100 \u00b0C may provide:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Temperature<\/th>\n<th>Output Current<\/th>\n<\/tr>\n<tr>\n<td>0 \u00b0C<\/td>\n<td>4 mA<\/td>\n<\/tr>\n<tr>\n<td>25 \u00b0C<\/td>\n<td>8 mA<\/td>\n<\/tr>\n<tr>\n<td>50 \u00b0C<\/td>\n<td>12 mA<\/td>\n<\/tr>\n<tr>\n<td>75 \u00b0C<\/td>\n<td>16 mA<\/td>\n<\/tr>\n<tr>\n<td>100 \u00b0C<\/td>\n<td>20 mA<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The Fluke Calibration 773 can verify the transmitter output current.<\/p>\n<p>However, the instrument does not generate RTD resistance values or thermocouple voltages for direct sensor simulation.<\/p>\n<p>A suitable temperature calibrator is required for complete temperature transmitter calibration.<\/p>\n<h2>Calibration of Pressure Transmitters<\/h2>\n<p>The Fluke Calibration 773 is also suitable for checking pressure transmitter output signals.<\/p>\n<p>Many industrial pressure transmitters use a 4 to 20 mA output.<\/p>\n<p>The instrument allows the output current to be measured without interrupting the circuit.<\/p>\n<p>This is particularly useful during maintenance and troubleshooting.<\/p>\n<p>For a complete pressure transmitter calibration, a suitable pressure reference and pressure generation system are additionally required.<\/p>\n<p>The Fluke Calibration 773 verifies the electrical signal but does not generate or measure pressure.<\/p>\n<h2>Testing PLC Inputs and Outputs<\/h2>\n<p>The Fluke Calibration 773 is particularly useful for testing programmable logic controllers.<\/p>\n<p>Industrial PLC systems frequently use standardized analog signals.<\/p>\n<p>Typical signal ranges include:<\/p>\n<ul>\n<li>4 to 20 mA<\/li>\n<li>0 to 20 mA<\/li>\n<li>0 to 10 V<\/li>\n<li>1 to 5 V<\/li>\n<\/ul>\n<p>The instrument can generate current and voltage signals to test PLC analog inputs.<\/p>\n<p>It can also measure current and voltage signals generated by compatible control system outputs.<\/p>\n<p>This makes the Fluke Calibration 773 a versatile instrument for industrial automation maintenance.<\/p>\n<h2>Portable Design<\/h2>\n<p>The Fluke Calibration 773 is designed for portable industrial applications.<\/p>\n<p>The instrument operates using four AA alkaline batteries.<\/p>\n<p>Its dimensions are approximately:<\/p>\n<p><strong>41.3 \u00d7 76 \u00d7 248 mm<\/strong><\/p>\n<p>The instrument weighs approximately:<\/p>\n<p><strong>415 g<\/strong><\/p>\n<p>The compact design makes it convenient for use in control cabinets, industrial facilities and field service applications.<\/p>\n<p>The instrument also includes a backlit display for improved readability.<\/p>\n<h2>Technical Highlights<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Specification<\/th>\n<th>Fluke
