A Relay Output is Not Responding Correctly
Confirm that the relay is properly configured within the
menu. Pay particular attention
to the selection of units, setpoints, limits, and mode options. Next, with power OFF, open the Control-
Panel by following the procedure as outlined in section titled
. Check that
the wires to the respective relay connector are in the proper contact position. The positions are clearly
marked on the PCB as Normally-Open (
NO
), Common (
COM
), and Normally-Closed (
NC
). Confirm that
sufficient insulation was removed from the wires to prevent the spring-loaded connector contacts from
pinching the insulation rather than the wire itself. The wires should stay in the connector even when
gently
tugged. Lastly, restore power to the Control-Panel and create the conditions that should cause
the relay to energize. Confirm whether or not the respective relay is being energized by the state of its
status LED. The LED should be ON whenever the relay is energized. If the problem persists, please call
the factory for further assistance.

Tare Weight Drift
It is common for accidental chemical spillage to accumulate on the Scale-Base leading to an unexpected
offset in the tare weight setting. Some Scale-Bases are equipped with an optional sensor designed to
detect liquid spills. Be sure to remove any build-up of dry chemicals or residue of liquid chemicals that
may otherwise taint a net measurement reading.
