SAFETY PRECAUTIONS

For safe and dependable operation of this product, please comply with the following precautions:

Operate the base only under ambient conditions specified in these instructions.
Ensure that the load cell cable does not pose an obstruction or tripping hazard.
Do not operate the base in hazardous environments or unstable locations.
Do not drop loads on the base.
Do not lift the base by the top frame; always lift from the bottom frame when moving the base.
Service should only be performed by authorized personnel.

ASSEMBLY

Weighing Pan

Remove the shipping spacers, and place the weighing pan securely over the rubber load pads on the top frame of the base.

Note: Not included with some models.

Wiring Connections

When connecting the 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 base to an indicator that does not have the matching connector, install the optional load cell cable adapter (P/N 30429931sold 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.

Detailed instructions that describe how to prepare the load cell cable for connection to the terminal block inside an indicator.
The extension cable accessory (P/N: 30429931) cannot be used if the scale will be used in a legal for trade or legally controlled application, because there is no provision to seal the connection between the indicator and platform.

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