2 weighing pan sizes: 254 x 254mm (10" x 10") and 305 x 305mm (12" x 12")

Resolutions: Maximum 1:6000 to 1:7500, Type-approved 1:3000

Food Safety Certifications: NSF, USDA / AMS

Supports HACCP compliance

Stainless steel frame, pan and load cell (IP67 dust and water ingress protected)

Adjustable non-slip rubber leveling feet with externally visible level indicator

6 rubber load pads and 6 down-stops for heavy-duty protection against shock and overload

Manufactured under an ISO 9001 compliant quality system

1.3 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

Save the packaging material. Re-pack the product using original packaging materials to ensure safe storage or transport.

2.2 Assembly

2.2.1 Weighing Pan

Place the weighing pan securely over the rubber load pads on the top plate of the base (first ensure that all load pads are seated fully in their respective mounting holes).

2.2.2 Wiring Connections

Connect the load cell cable to an indicator using the wiring codes in Tables 2-1 and 2-2 below. Refer to the indicator manual for information about load cell connections, setup and calibration.

Note: When purchased as a CKW scale, the base is already pre-wired to the CKW-55 Indicator.

2.3 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 (located at the rear of the base) 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

3.MAINTENANCE

3.1 Cleaning

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

Avoid directly spraying the load cell with high-pressure water jets

Water with a mild detergent may be used to clean the external and internal surfaces—do not use acids, alkalis, strong solvents or abrasive materials and chemicals

The pan extends past the bottom plate to minimize entry of water or foreign material into the frame. As necessary, remove the pan to wipe or wash down the internal surfaces of the base.

Removable components such as the weighing pan, leveling feet and rubber load pads (including column and CKW-55 Indicator when purchased as a scale system) may be removed and cleaned accordingly

3.2 Troubleshooting

Aside from installing components (Section 2.2) and leveling adjustments (Section 2.3), the CKW 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 weighing pan or base frame

Unstable environments

Incorrect calibration or setup of the indicator

If operational difficulties remain unresolved, contact your dealer or an authorized Ohaus Service Agent. Repairs should be made by authorized service personnel only.

For service assistance in the United States and Canada, you may call Ohaus Corporation toll free at (800) 5260659 from 8 AM to 5 PM Eastern Time. An Ohaus Product Service Specialist will be available to help you.
