ASSEMBLY

Weighing Pan

Wiring Connections

DxxxHx, DxxxQx, and DxxxRx Bases

When connecting the DxxxHx, DxxxQx, or DxxxRx base to an Ohaus indicator equipped with the matching circular connector,
push the base connector onto the indicator connector and turn the locking ring clockwise to lock it in place.

When connecting the DxxxHx, DxxxQx, or DxxxRx base to an indicator that does not have the matching connector, install the
optional load cell cable adapter (P/N 80500736 sold separately) to the indicator using the wiring codes in Table 1. Then attach
the load cell cable to the cable adapter.

Note: As an alternate wiring method, cut off the connector, strip the wires and attach them to the indicator using the wiring codes
in Table 1.

DxxxWx Bases

Install the load cell cable to an indicator using the wiring codes in Table 1.

Note: When purchased as a Defender Series Scale, the DxxxWx base is already pre-wired to the indicator.

Selecting the Location

To ensure accuracy, proper performance and safety, locate and operate the base on a stable, level surface. Avoid locations with
rapid temperature changes or excessive dust, air currents, vibrations, electromagnetic fields or heat.

Level the base by adjusting the four leveling feet until the bubble in the level indicator is centered. A wrench may be needed to
loosen the locking nut above each leveling foot. When the base is level, retighten the locking nuts up against the base to lock
each foot into place.

Note: Ensure that the base is level each time its location is changed.

CORRECT INCORRECT

MAINTENANCE

Cleaning

The base components should be kept clean and free of excessive material build up.

• A damp cloth with water and a mild detergent may be used to wipe clean the external surfaces – do not use acids,

alkalis, strong solvents or abrasive materials.

To maintain surface integrity, do not allow food particles or liquids to remain on the surface of the painted or stainless steel base
frame.

• Remove the pan and use fresh water to clean the base frame surface of any food particles or liquids. Dry the base with

a clean cloth or allow to air dry before replacing the pan. Repeat daily for best care.

Troubleshooting

Aside from installing components and leveling adjustments, the Defender Series Base does not require any other adjustments as
shipped from the factory.

Operational difficulties that may be encountered can often be traced to simple causes such as:

• Loose or incorrect wiring connections

• Obstructions to the base frame

• Unstable environments

• Incorrect calibration or setup of the indicator
