Safety Precautions

CAUTION: Read all safety warnings before installing, making connections, or servicing

this equipment. Failure to comply with these warnings could result in personal injury and/or property damage. Retain all instructions for future reference.

 Verify that the AC adapter’s input voltage range and plug type are compatible with the local

AC main power supply.

 Make sure that the power cord does not pose a potential obstacle or tripping hazard.  Do not position the balance such that it is difficult to reach the power connection.  The balance is for indoor use only. Do not operate the equipment in hazardous or unstable

environments.

 Operate the equipment only under ambient conditions specified in these instructions.  Do not drop loads on the pan.  Use the balance only in dry locations.  Disconnect the equipment from the power supply when cleaning.  Use only approved accessories and peripherals.  Service should only be performed by authorized personnel.

Intended Use

Use the instrument exclusively for weighing as described in the operating instructions. Any other type of use and operation beyond the limits of technical specifications without written consent from OHAUS, is considered as not intended. This instrument complies with current industry standards and the recognized safety regulations; however, it can constitute a hazard in use. If the instrument is not used according to these operating instructions, the intended protection of the instrument may be compromised and OHAUS assumes no liability.

2. INSTALLATION

2.1 Select the Location

Avoid heat sources, rapid temperature changes, air current or excessive vibrations. Allow sufficient space.

2.2 Leveling

Be sure the balance is level before it is used or after its location is changed. The PR balance has a level bubble in a small round window beside the display. To level the balance, adjust the 2 leveling feet until the bubble is centered in the circle. Please refer to the right figure for leveling.

2.3 Connecting Power and Acclimatising the Balance

Connect the DC output connector to the power receptacle on the rear of the balance. Then connect the AC adapter plug to a suitable electrical outlet.

Acclimatising

It is suggested that the balance should not be used until it has been connected to power and acclimatised to the environment for a certain period of time. In the case of a balance with the precision above 0.1 mg, the acclimatisation time should be 1.5 hours; in the case of balance with the precision of 0.01 mg, the acclimatisation time should be more than 4 hours.

2.4 Connecting the Interface

The PR balance has a RS232 port. Use the RS-232 port to connect either to a computer or a printer with a standard (straight-through) serial cable. Interface connections on the rear of the balance

RS232：Used to connect to PC or Printer Note: See the Printing section for Connecting, Configuring and Testing the Printer / Computer

Interface.

3.2 Principal Functions

Weighing:

First press Zero to set the display to zero. Place an object on the pan. The display indicates the gross weight.

Taring:

With no load on the pan, press Zero to set the display to zero. Place an empty container on the pan and press Tare. Add objects to the container and its net weight is displayed. After the container and the objects are removed, the load will be displayed as a negative number. Press Tare to clear.

Zero:

Press Zero to zero the balance.

4. MAINTENANCE

4.1 Cleaning

WARNING: Disconnect the balance from the power supply before cleaning.

Make sure that no liquid enters the interior of the balance.

Clean the balance at regular intervals. Housing surfaces may be cleaned with a lint-free cloth slightly dampened with water or a mild cleaning agent. Glass surfaces may be cleaned with a commercial glass cleaner.

Attention: Do not use solvents, harsh chemicals, ammonia or abrasive cleaning agents.

4.2 Troubleshooting

If the troubleshooting section does not resolve your problem, contact an Authorized Ohaus Service Agent. Please visit our website www.ohaus.com to locate the Ohaus office nearest you.
