INTRODUCTION
This manual covers installation, and maintenance instructions for the OHAUS Defender TM Series Base. Please
read this manual completely before installation and operation.
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
INSTALLATION
Unpacking
Unpack and inspect the product to make sure that all components have been included. The package includes the
following:
• Defender TM Series Base • Weighing Pan • Instruction Manual
When purchased as a complete Defender Series Scale, the package will also include:
• Indicator • Column Assembly
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.

EN-2 Defender Series Base
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.

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 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.

 Failure to remove the shipping spacers
 Obstructions to the base frame
 Unstable environments
 Incorrect calibration or setup of the indicator
