CHAPTER 3 REPAIR PROCEDURES
3000 Series T32ME & MC Indicators Service Manual 3-1 Ohaus Corporation www.ohaus.com
3.1 PREVENTIVE MAINTENANCE
Ohaus Indicators are precision instruments and should be carefully handled, stored in a clean,
dry, dust-free area, and cleaned periodically. Follow these precautionary steps:
– When an Indicator has had chemicals or liquids spilled on it, all exterior surfaces should
be cleaned as soon as possible with warm water on a damp cloth.
– Allow at least 10 minutes for the Indicator to stabilize after the indicator reaches the
temperature of the environment.
3.1.1 Preventive Maintenance Checklist
The Indicator should be inspected and checked regularly, as follows:
1. Unplug the AC Adapter before cleaning.
2. Clean the outside using a cloth dampened with a mild detergent.
CAUTION
DO NOT USE CHEMICAL CLEANERS OR SOLVENTS OF ANY TYPE.
SOME CLEANERS ARE ABRASIVE AND MAY AFFECT THE SCALE’S FINISH.
3. Check the Power Cord for broken or damaged insulation.
4. Make a visual inspection for faulty connectors, wiring, and loose hardware.
3.2 TESTING AND REPLACEMENT OF MAJOR COMPONENTS
The decision to replace any component should only be made after thoroughly diagnosing the
problem. This chapter provides guidance for testing all components prior to replacement. It
includes an explanation of how load cells work, and how a load cell simulator may be used to
test the indicator.
If, after the replacement of any component, the Indicator is still non-functional and no other
information on the subject is available in the manual, contact Ohaus Corporation by visiting
www.ohaus.com. In the United States call Ohaus Aftermarket toll free, 800-526-0659 between
