The FLUKE 789 is the ultimate troubleshooting tool for electricians and instrumentation professionals.ĭiode test indication: displays voltage drop acroos device 2.0V full scale 0.2mA nominal test current at 0.Designed to help keep your process up and running!.Minimum sensitivity DC (RMS Sinewave) 5Hz to 5kHz: 150mV / 1V / 4V / 40V / 400V.Minimum sensitivity AC (RMS Sinewave) 5Hz to 5kHz: 150mV (50Hz to 5kHz) / 1V / 4V / 40V / 400V.Typical burden voltage: 14mV/mA / 1.5V/A.It comes supplied with red/black test leads, test probes and crocodile clips alongside product documentation. The FLUKE 789 Process Meter is a combination of a 4-20 milliamp loop calibrator and a CAT IV to 600-Volts safety rated Digital Multimeter (DMM) with an impressive display. In the Milliamp function, the built-in loop calibrator sources a 4-20 milliamp signal to test devices with a 4-20 Amp input such as a PLC I/O or analogue milliamp indicator. The 789 also has a Ramping function that allows you to Ramp the milliamp signal into the indicator, or other input device at one location and go to the device and check for an appropriate response, such as a valve stem indicator change or mode indicator of a control system.
