Connections to test continuity using a switching module are shown below.
Because this is a 2-wire ohms measurement, Channels 1 through 40 of a 40-
channel switching module can be used.

Continuity testing procedure
NOTE
If the Series 3700 is in remote, place the unit in local by pressing the
LOCAL
key
(or the
EXIT
key).
Refer to DCV measurements for function configuration and menus.
1. Set threshold resistance:
Turn the navigation wheel to scroll to the "THRESHOLD" menu item
(right most menu item) and press the
ENTER
key.
Using the navigation wheel, dial in the desired resistance to be used as
a threshold (1
–1000 .
Press the
ENTER
key
to set.
Press the
EXIT
key
to leave the "CONT ATTR MENU."
2. Apply the resistance to be tested. If using a switching module, perform the
following steps to close the appropriate channel.
a. Use the navigation wheel to dial in the channel number.
b. Press the
CLOSE
key.
3. Press the
TRIG
key and observe the displayed reading.
4. To measure other switching channels, repeat steps 5 and 6.
NOTE
If the measured circuit is below the set threshold level, the
instrument will display the resistance readings. If the measured
circuit is above the threshold level, the instrument will display the
message "OPEN."
