Fluke ProcessMeter 787B Information The Fluke ProcessMeter 787B is a digital multimeter (DMM) and mA loop calibrator in one compact instrument. It combines the trusted measurement capabilities of the Fluke 87V meter with the ability to measure, source, and simulate mA with the accuracy and resolution you would expect from a Fluke mA loop calibrator. This makes it the ideal tool for troubleshooting and calibrating current loop applications. Here is an overview of the Fluke ProcessMeter 787B: Measurements: The 787B can measure DC voltage, AC voltage, DC current, AC current, resistance, capacitance, frequency, duty cycle, diode test, and continuity. It also has a True RMS measurement mode for accurate measurements of AC signals. Loop Calibration: The 787B can be used to calibrate current loop transmitters and controllers. It can source and measure 20 mA DC current, and it can also simulate mA current. This makes it the ideal tool for verifying the accuracy of your current loop signals. ...
