New process Meter fit FLUKE H787 loop calibrator T-RMS
TheH787 Process Meterwas the first tool to combine a loop calibrator with a fully-functional 1000V True RMS digital multimeter to give process technicians double the power in one tool.
A maintenance and calibration tool that will be at home in every instrumentation technician\'s tool box, the Fluke 787 Process Meter combines a DMM and a Loop Calibrator in one rugged, handheld tool, for about what you would expect to pay for a loop calibrator alone. The H787 adds the ability to measure, source, and simulate dc loop current with 0.05% accuracy and 1 microamp resolution.
Put it all together and you have the ideal tool for troubleshooting and calibrating current loop applications. So if you\'re tired of always tracking down a calibrator, lugging around two tools and switching back and forth, get the single best solution for doubling your power - the H787 Process Meter.
1. True Root Mean Square (TRUE RMS) measurement.
All measured value of AC voltage and AC current of this instrument are TRUE RMS, which is differential from low-end instruments that only measure the AC averages.
2. Manual/Auto Range
3. Percentage Range
4. Relative Value Measuring
6. Data Hold
7. Low power Detection
8. Backlight Control
9. This ProcessMeter can deliver steady, phase stepped or linear increasing current output to the loop with current 0-20 mA and/or 4-20 mA. It has three work models:
Current source model: enable the ProcessMeter to provide current to transmitters or passive circuits without supplying from external loops.
Analog current model: enable the ProcessMeter to adjust the current on external power (12-32 V) in the loop, which emulates a 2-wire transmitter.
Loop power model: enable the ProcessMeter to provide external equipment\'s power and measure the loop current.
