DESCRIPTION

Carefully unpack the balance, verify that all items are on hand.  Save the

packing material for transporting the balance.

    UNPACKING

All balances are shipped with the following components:

•  Weighing Platform

•  Instruction manual

 •  Power adapter

Your Ohaus Analytical balance is a precision weighing instrument, designed to

provide years of service.  Simple three button operation allows for the selection of

units, calibration and printing parameters.  A standard RS232 interface permits

communication to an external printer or computer.  Power is supplied through an

AC adapter.

  INSTALLATION

For best performance, the balance should be used in a clean, stable environment.

Do not use the balance in environments with excessive drafts, near magnetic

fields or equipment that generates magnetic fields, rapid temperature changes,

vibrations or corrosive vapors.

Setting Up and Leveling the Balance

For exact horizontal positioning, the balance is equipped with a level indicator

and two leveling feet located at the rear of the balance.

Position the balance in the intended operating location.  Adjust the leveling feet at

the rear of the balance until the air bubble in the indicator is centered.

NOTE: The instrument should be leveled each time its location is changed.

BUBBLE LEVEL

LEVELING FEET (2)

Pan Installation

Slide open the door and insert the platform in the balance.  The balance is now

ready for operation.
