NOTE
Make sure the INPUTS switch is in the correct position. To use front panel
inputs, it must be in the “F” (out) position. For switching modules, it must be in
the “R” (in) position.
Perform the following steps to measure resistance:
1.
If a switching channel is presently closed (displayed), press OPEN to open it.
2.
Select the ohms measurement function by pressing
