Continuity testing procedure
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.
1. Apply the resistance to be tested and, if using a switching module, close the
appropriate channel.
2. Press SHIFT and then CONT to display the present threshold LEVEL.
3. Use , , , and to key in the desired level (1 to 1000
Ω
) and press ENTER.
If the measured circuit is below the set threshold level, the instrument will beep
and display the resistance readings.
If the measured circuit is above the threshold level, the instrument will not beep
and either display the resistance reading or the message “OPEN”.
If the reading is below 1100
Ω
, it will be displayed. If the reading is 1100
Ω
or above,
“OPEN” will instead be displayed.
4. To disable continuity testing, select a different function (i.e., press DCV).
NOTE The beeper can be disabled using the SYSTem:BEEPer:STATe OFF command.
However, the beeper will automatically enable the next time the continuity
testing function is selected.
Limits and digital outputs cannot be used when testing continuity with the
continuity (CONT) function. If you need to use these operations, use the
Ω
2
function to test continuity.
