5-15. Resistance Test
Use the following procedure to verify proper operation of the resistance
function:
1. Connect the UUT and the DMM Calibrator as shown in Figure 5-4.
2. Select the resistance function and follow the steps 1 through 7 as listed
in Table 5-3. For each step, select the UUT function and range as
indicated. Program the DMM Calibrator for the specified input signal
and verify that the displayed UUT value is within the indicated limits.

(optional steps 8 and
9 in Table 5-3), disconnect the DMM Calibrator and connect a
precision Reference Resistor for each value.
