5. Press the
TRIG
key and observe the displayed reading.
6. To measure other switching channels, repeat steps 5 and 6.
7. When finished, press the
OPENALL
key to open all channels.
NOTE
Also see the bus command
dmm.threshold
for more information on
threshold attributes.
Continuity testing
The Series 3700 can test continuity using the 2-wire 1k range with a user
selectable threshold resistance level (1 to 1000 ). When the measured circuit is
below the set threshold level, the instrument will display the resistance readings.
When the measured circuit is above the threshold level, the instrument will
display the message "OPEN."
NOTE
The reading rate for continuity is fixed at 0.006 PLC. Limits and digital
outputs cannot be used when testing continuity with the continuity
(CONT) function. If you need to use these operations, use the 2
function to test continuity.
NOTE
The continuity function does not support REL. Use mx + b, with b as
an offset, to compensate for cable and 3700 card path resistance.
Continuity testing connections
When using the rear analog backplane connector, connect the test leads to the
INPUT HI and LO terminals as shown below.
