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 provides a continuous mA signal that corresponds to the 4 to 20 mA signal measured by the mA clamp Output mA signal 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 Apply a mA input signal to a device and measure its 4 to 20 mA output on devices such as valves or mA isolators Voltage output linear ramp or 25% step output Automatically change the voltage output for remote testing
