This manual covers installation, operation and maintenance instructions for the Ohaus CKW Base. Please read
this manual completely before installation and operation.
1.1. General Description
The Ohaus CKW Series is available as stand-alone scale bases or as complete weighing systems with the CKW-
55 Indicator. The CKW Base is engineered for static checkweighing operations that also accommodates all
types of weighing applications—from general purpose to washdown. With its easy-to-clean design to minimize
food traps, food safety certification and rigid stainless steel construction, the CKW Base is ideally suited for years
of use in harsh environments, and other wet-environment applications where sanitary requirements are high.
1.2 Features
4 Capacity Models: 3kg/6lb, 6kg/15lb, 15kg/30lb, 30kg/60lb
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
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 plate; always lift from the bottom plate when moving the base
Service should only be performed by authorized personnel

2. INSTALLATION
2.1 Unpacking
Unpack and inspect the product to make sure that all components have been included. The CKW Base package
includes the following:
CKW Base Weighing Pan Warranty Card Instruction Manual
When purchased as a complete CKW scale, will also include:
CKW-55 Indicator Column Assembly
Check to ensure the product was not damaged during shipping. Immediately inform your OHAUS dealer in the
unlikely event that you find damaged or missing parts.
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.

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.

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) 526-
0659 from 8 AM to 5 PM Eastern Time. An Ohaus Product Service Specialist will be available to help you.
