Industrial Process Calibration<\/h2>\n<p>The Fluke Calibration 789 is designed for technicians working with industrial process instrumentation.<\/p>\n<p>Modern industrial plants use numerous sensors and transmitters to monitor pressure, temperature, flow, level and other process variables.<\/p>\n<p>Many of these instruments transmit their measurement results using standardized 4\u201320 mA current signals.<\/p>\n<p>The Fluke Calibration 789 provides the functions required to check these signals directly in the field.<\/p>\n<p>Technicians can measure loop current, simulate transmitter signals and source defined current values to verify the operation of control systems.<\/p>\n<p>The integrated digital multimeter also allows electrical measurements without carrying an additional instrument.<\/p>\n<p>Typical applications include process transmitter testing, industrial maintenance, control loop troubleshooting and commissioning.<\/p>\n<h2>4\u201320 mA Current Measurement<\/h2>\n<p>One of the most important functions of the Fluke Calibration 789 is accurate current measurement.<\/p>\n<p>The instrument provides a dedicated measurement range from:<\/p>\n<p><strong>0 to 30 mA<\/strong><\/p>\n<p>The measurement resolution is:<\/p>\n<p><strong>0.001 mA<\/strong><\/p>\n<p>The specified accuracy is:<\/p>\n<p><strong>\u00b1(0.05% of reading + 2 counts)<\/strong><\/p>\n<p>This measurement capability is particularly useful for checking industrial 4\u201320 mA current loops.<\/p>\n<p>For example, a pressure transmitter may be configured to generate 4 mA at the lower range limit and 20 mA at the upper range limit.<\/p>\n<p>The Fluke Calibration 789 allows technicians to measure the actual transmitter output and compare it with the expected value.<\/p>\n<p>Intermediate measurement points can also be checked to verify transmitter linearity.<\/p>\n<h2>4\u201320 mA Current Sourcing<\/h2>\n<p>The Fluke Calibration 789 can generate precise current signals.<\/p>\n<p>The current sourcing range is:<\/p>\n<p><strong>0 to 20 mA<\/strong><\/p>\n<p>The output resolution is:<\/p>\n<p><strong>0.001 mA<\/strong><\/p>\n<p>The manufacturer specifies a current sourcing accuracy of:<\/p>\n<p><strong>\u00b10.05% of span<\/strong><\/p>\n<p>The current output can be used to test devices that normally receive a signal from a process transmitter.<\/p>\n<p>Typical examples include:<\/p>\n<ul>\n<li>PLC analog inputs<\/li>\n<li>Process indicators<\/li>\n<li>Data acquisition systems<\/li>\n<li>Control systems<\/li>\n<li>Current-to-pressure converters<\/li>\n<li>Industrial signal processing equipment<\/li>\n<\/ul>\n<p>The technician can generate a defined current signal and check the response of the connected device.<\/p>\n<p>This allows the measurement and control system to be tested independently of the original process transmitter.<\/p>\n<h2>Current Simulation<\/h2>\n<p>In addition to generating current, the Fluke Calibration 789 can simulate a two-wire transmitter.<\/p>\n<p>In simulation mode, the instrument controls the current flowing through an externally powered loop.<\/p>\n<p>This function is useful when testing control systems that already provide loop power.<\/p>\n<p>The Fluke Calibration 789 can replace the transmitter temporarily and generate the required process signal.<\/p>\n<p>The receiving instrument can then be checked at different current values.<\/p>\n<p>It is important to distinguish between current sourcing and current simulation.<\/p>\n<p>In sourcing mode, the ProcessMeter provides the current using its internal source.<\/p>\n<p>In simulation mode, an external loop supply is required.<\/p>\n<h2>Integrated 24 V Loop Power Supply<\/h2>\n<p>The Fluke Calibration 789 features an integrated:<\/p>\n<p><strong>24 V loop power supply<\/strong><\/p>\n<p>This function allows technicians to power compatible two-wire transmitters during testing.<\/p>\n<p>A separate external loop power supply is therefore unnecessary for many routine calibration and troubleshooting tasks.<\/p>\n<p>The integrated supply is particularly useful when a transmitter has been removed from an industrial installation.<\/p>\n<p>It can also be used during commissioning or maintenance when the normal process control system is unavailable.<\/p>\n<p>The loop power supply simplifies testing and reduces the amount of equipment required in the field.<\/p>\n<h2>Integrated 250 \u03a9 HART Resistor<\/h2>\n<p>The Fluke Calibration 789 includes a selectable:<\/p>\n<p><strong>250 \u03a9 HART resistor<\/strong><\/p>\n<p>HART communication is widely used in industrial process instrumentation.<\/p>\n<p>Many HART communication systems require a suitable load resistance to allow reliable communication.<\/p>\n<p>The integrated resistor eliminates the need to connect a separate external resistor for many applications.<\/p>\n<p>This simplifies the connection of compatible HART transmitters and communicators.<\/p>\n<p>The Fluke Calibration 789 does not function as a standalone HART communicator.<\/p>\n<p>A suitable external HART communication device is required for accessing transmitter parameters and digital communication functions.<\/p>\n<h2>Automatic Current Stepping<\/h2>\n<p>The Fluke Calibration 789 supports automatic current stepping.<\/p>\n<p>This function allows technicians to generate predefined current values without manually adjusting each individual output.<\/p>\n<p>For a standard 4\u201320 mA process signal, typical test points include:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Percentage of Span<\/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 are particularly useful for checking the linearity of analog inputs and process indicators.<\/p>\n<p>The automatic stepping function helps reduce manual operation during repetitive tests.<\/p>\n<h2>Automatic Current Ramp<\/h2>\n<p>The Fluke Calibration 789 also provides an automatic ramp function.<\/p>\n<p>Instead of generating individual current steps, the instrument continuously changes the output current within the selected range.<\/p>\n<p>This function is useful for checking the response of analog process instruments.<\/p>\n<p>Typical applications include verifying display behavior, testing control system responses and identifying switching points.<\/p>\n<p>Automatic ramp generation can also be useful when testing process alarms.<\/p>\n<p>The ramp function reduces the need for continuous manual adjustment.<\/p>\n<h2>Dedicated 0% and 100% Buttons<\/h2>\n<p>The Fluke Calibration 789 features dedicated buttons for selecting the lower and upper values of a standard process current signal.<\/p>\n<p>These buttons allow quick switching between:<\/p>\n<p><strong>4 mA and 20 mA<\/strong><\/p>\n<p>This function is especially useful during commissioning and troubleshooting.<\/p>\n<p>For example, technicians can quickly verify whether a connected process indicator correctly displays its lower and upper range limits.<\/p>\n<p>The dedicated buttons simplify routine testing and improve operating efficiency.<\/p>\n<h2>Digital Multimeter Functions<\/h2>\n<p>The Fluke Calibration 789 combines its loop calibration capabilities with a professional digital multimeter.<\/p>\n<p>The instrument can measure:<\/p>\n<ul>\n<li>DC voltage<\/li>\n<li>AC voltage<\/li>\n<li>DC current<\/li>\n<li>AC current<\/li>\n<li>Resistance<\/li>\n<li>Frequency<\/li>\n<li>Continuity<\/li>\n<li>Diode voltage<\/li>\n<\/ul>\n<p>This combination makes the instrument particularly useful for industrial maintenance.<\/p>\n<p>Technicians can check both the electrical supply conditions and the process signals using one instrument.<\/p>\n<p>The integrated multimeter helps identify wiring problems, incorrect supply voltages and defective electrical connections.<\/p>\n<h2>DC Voltage Measurement<\/h2>\n<p>The Fluke Calibration 789 provides DC voltage measurement up to:<\/p>\n<p><strong>1000 V<\/strong><\/p>\n<p>The manufacturer specifies an accuracy of:<\/p>\n<p><strong>\u00b1(0.1% of reading + 1 count)<\/strong><\/p>\n<p>This makes the instrument suitable for checking electrical supply voltages and industrial control circuits.<\/p>\n<p>Typical applications include checking DC power supplies, transmitter supply voltages and control cabinet wiring.<\/p>\n<p>The actual resolution depends on the selected measurement range.<\/p>\n<h2>True RMS AC Voltage Measurement<\/h2>\n<p>The Fluke Calibration 789 provides True RMS AC voltage measurement.<\/p>\n<p>The maximum AC voltage measurement range is:<\/p>\n<p><strong>1000 V<\/strong><\/p>\n<p>True RMS measurement allows the instrument to determine the effective value of AC voltages, including many non-sinusoidal waveforms.<\/p>\n<p>This is useful in industrial environments where electrical signals may be distorted.<\/p>\n<p>The applicable accuracy depends on signal frequency, waveform and measurement range.<\/p>\n<h2>Resistance Measurement<\/h2>\n<p>The Fluke Calibration 789 can measure electrical resistance up to:<\/p>\n<p><strong>40 M\u03a9<\/strong><\/p>\n<p>The manufacturer specifies a basic resistance measurement accuracy of:<\/p>\n<p><strong>\u00b1(0.2% of reading + 1 count)<\/strong><\/p>\n<p>Resistance measurement is useful for checking wiring, electrical components and connections.<\/p>\n<p>The function can also assist with troubleshooting industrial instrumentation.<\/p>\n<p>For precise resistance thermometer calibration, however, a dedicated RTD calibrator or suitable resistance measurement system may be more appropriate.<\/p>\n<h2>Frequency Measurement<\/h2>\n<p>The Fluke Calibration 789 supports frequency measurement up to approximately:<\/p>\n<p><strong>20 kHz<\/strong><\/p>\n<p>The manufacturer specifies a frequency measurement accuracy of:<\/p>\n<p><strong>\u00b1(0.005% of reading + 1 count)<\/strong><\/p>\n<p>This function can be used for checking electrical frequency signals in industrial systems.<\/p>\n<p>Typical applications include signal generators, pulse outputs and certain process measurement instruments.<\/p>\n<h2>Continuity and Diode Testing<\/h2>\n<p>The Fluke Calibration 789 provides continuity testing with an audible signal.<\/p>\n<p>The continuity function helps technicians identify electrical connections and interruptions.<\/p>\n<p>The instrument also includes a diode test function.<\/p>\n<p>These features are particularly useful for troubleshooting wiring and electrical components.<\/p>\n<h2>Large Dual Display<\/h2>\n<p>The Fluke Calibration 789 features a large dual display with adjustable backlighting.<\/p>\n<p>The display allows technicians to read measurement values clearly in industrial environments.<\/p>\n<p>For process current measurements, the instrument can display the current value and percentage of span simultaneously.<\/p>\n<p>This simplifies the interpretation of 4\u201320 mA signals.<\/p>\n<p>For example, a current of 12 mA corresponds to 50% of a standard 4\u201320 mA measurement span.<\/p>\n<p>The percentage display eliminates the need for manual conversion during many routine checks.<\/p>\n<h2>Min, Max and Average Functions<\/h2>\n<p>The Fluke Calibration 789 provides additional digital multimeter functions.<\/p>\n<p>These include minimum, maximum and average value recording.<\/p>\n<p>The functions are useful for investigating changing electrical signals.<\/p>\n<p>The Hold function allows a displayed measurement value to be retained.<\/p>\n<p>These capabilities help technicians evaluate signal behavior during troubleshooting.<\/p>\n<h2>Optional Fluke Connect Compatibility<\/h2>\n<p>The Fluke Calibration 789 can be used with Fluke Connect when equipped with the optional IR3000FC communication module.<\/p>\n<p>This allows compatible measurement data to be transferred wirelessly.<\/p>\n<p>The optional module is not included with the standard instrument.<\/p>\n<p>Fluke Connect functionality depends on the installed accessories, software and supported devices.<\/p>\n<h2>Electrical Safety<\/h2>\n<p>The Fluke
