Current

This function measures the current flowing into the Red and Black test leads (and a 430 Ohm resistor inside the 965DSP-B). Connect the Red and Black leads to the pair to measure loop current. Connect the Red lead to the voltage side of the pair and the Black lead to ground to measure ground current.

If the Current is greater than 110 mA , you will see the following ‘Current Warning’ screen:

This screen indicates that a high current has been detected between the test leads and that the 965DSP-B has opened an internal relay to protect itself from damage. Use standard safety practices for disconnecting the test leads. Press the [Enter] key to start the Current test again.
