The three output relays are located on the measurement
board.
They can be individually configured to Normally Open (NO) or
to Normally Closed (NC) by physically moving the jumper on
each relay. On the picture example on the left:
• Upper relay is set to NC
• Middle relay is set to NO
• Lower relay is shown with no jumper
Note: J14 (upper relay) is relay 1
J18 (middle relay) is relay 2
J19 (lower relay) is relay 3
