4.17 Configure the relays
If a relay(s) in the analyzer is connected to an external device, select the triggers that set the relay to
on (active). The relay status shows at the top-right corner of the measurement screen. Refer to
Figure 3 on page 6.
Note: The Normally Open (NO) and Common (COM) relay contacts are connected when the relay is on. The
Normally Closed (NC) and Common relay contacts are connected when an the relay is off.
1. Enable a relay as follows:
a. Push menu, then select SETUP SYSTEM > CONFIGURE ANALYZER > SETUP OUTPUTS
