DC voltage measurement to verify 24 V power supplies or voltage I/O signals
Source dc voltage to test input devices that accept a 1 to 5 volt or 0 to 10 volt signal
Scaled mA output corresponds to the 4 to 20 mA signal measured by the mA clamp enables a logging DMM or other device to record the 4 to 20 mA signal without breaking the loop mA in/out: simultaneously measure the mA signal with the clamp and source a mA signal
Voltage output linear ramp or 25 % step output
Automatically change the voltage output for remote testing

4 AA alkaline batteries, test lead set with integral prods and 2 crocodile clips; test leads with integral grabber clips; soft carry case & instructions

The Fluke milliamp process clamp meter measures current up to 99.9mA DC and voltage up to 30V DC. It saves time and money by measuring 4mA to 20mA signals five times faster than with traditional DMMs, and without breaking the loop. It can detach the clamp section of the meter and use it as a remote jaw, connected to the main body by an extension cable to make it easier to take measurements in tight spaces.
