Resistance This section describes how to configure 2 and 4-wire resistance measurements from the front panel. Step 1: Configure the test leads, as shown below. 2 wire resistance: 4 wire resistance: Step 2: press the front panel [ Ω 2 w] or [ Ω 4 w] . The following menu appears. (Ω 4Wmenu does not include Auto Zero ) Step 3: For the HDM3000, use the Up/Down arrow keys to specify the integration time in the Power Line Cycle Number (PLC) for measurement with Aperture NPLC=10PLC by default.1, 10 and 100 PLCs provide normal mode (line frequency noise) 34
