CHAPTER 3 MAINTENANCE PROCEDURES
7000 Series T71 Indicators Service Manual 3-1 Ohaus Corporation www.ohaus.com
3.1 PREVENTIVE MAINTENANCE
The T72XW terminal is designed to provide years of dependable operation.
However, OHAUS CORPORTATION recommends that
– as with any industrial measurement
equipment
– the terminal and the connected scale system be serviced periodically.
Timely, factory-specified maintenance and calibration by a OHAUS CORPORTATION
authorized service technician will ensure and document accurate and dependable performance
to specifications.
3.1.1 Cleaning and Maintenance
Clean the terminal’s keypad and cover with a clean, soft cloth that has been dampened with a
mild glass cleaner. Do not use any type of industrial solvent such as toluene or isopropanol
(IPA) that could damage the terminal’s finish. Do not spray cleaner directly on the terminal.
Regular maintenance inspections and calibration by a qualified service technician are
recommended.
The T72XW terminal is a rugged instrument; however, the front panel is a relatively thin
covering over sensitive electronic switches and a lighted display. Care should be taken to avoid
any punctures to this surface or any vibrations or shocks to the instrument. If the front panel is
punctured, ensure that steps are taken to prevent dust and moisture from entering the unit until
the terminal can be repaired.
3.2 REPLACEMENT OF MAJOR COMPONENTS
The decision to replace any component should only be made after thoroughly diagnosing the
problem. 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
