NOTE Source current flows from input high to input low.
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.
Apply the resistance to be tested and if using a switching module, close the appro-
priate channel(s).
Press SHIFT and then CONT to display the present threshold LEVEL.
Use

, and
ENTER.
If the measurement is below the threshold level, the beeper will sound and the
ohms reading will be displayed. If the measurement is above the threshold level,
the message "OPEN" will be displayed.
To disable continuity testing, select a different function (i.e., press DCV).
The beeper can be disabled using the SYSTem:BEEPer:STATe OFF command.
However, the beeper will automatically enable the next time the continuity test-
ing function is selected.
Limits and digital outputs cannot be used when testing continuity with the conti-
nuity (CONT) function. If you need to use these operations, use the Ω2 function
to test continuity.
