Note
For best results, the filter may require zeroing during the
ohms function.
Refer to the “Range Keys” section in Chapter 3 of this manual for information on how to
adjust the measurement range.
Making a Four-wire Resistance Measurement
The Meter incorporates two methods of making a four-wire resistance measurement. The
traditional method is to use four meter leads to connect the Meter to the resistance to be
measured. The optional 2X4 Wire test leads simplifies the four-wire measurement so you
only have to plug in two test leads to the front-panel Input HI and LO connectors of the
meter.
To make a four-wire resistance measurement using four test leads:
1. Connect the test leads to the Meter’s input connectors as shown in Figure 4-2.
2. Press N.
