Warning
The Calibrator should only be opened by qualified
electrical/mechanical service technicians. Lethal voltages are
present and exposed in the power supply and display.
1. Turn off the Calibrator and disconnect the power cord from the power supply.
2. Locate the screws that secure the cover.
3. Unscrew these screws and remove the cover.
4. Replace the cover before resuming operation.
Processor Battery
The processor board uses a lithium battery to maintain time and date information. This
battery has a varying life. If the instrument is left on 24 hours a day it will last 5-10 years.
If the instrument is stored, it will last one year. It is recommended to replace it every year.
To do this, follow the instructions below:
1.
Remove cover, see section above, Chapter 6, Preventative Maintenance, Removing
the Calibrator’s Cover.
2. Remove processor card by removing one screw and rocking upward.
3. Remove battery, a round silver object, by carefully pulling on battery while
holding card.
4. Plug in new battery (part number 4-725).
5. Reassemble in reverse order.
6. The time and date may have to be re-entered. See Chapter 4, Configuration,
Time/Date.
Calibration
To keep the Calibrator operating within its specified accuracy (Appendix A), the
calibration procedure described below must be performed. Use appropriate DWG, such
as RUSKA 2485.
Note
The calibration procedure automatically generates coefficients which are
stored in memory on the Calibrator’s Control Board (Chapter 2). If these
constants are “lost” for any reason, the calibration procedure must be
performed, regardless of the last calibration date. If the calibration
coefficients are known, they may be restored to the Calibrator at any time
by “editing the coefficients” (Chapter 6, Subsection under Storing the
Coefficients,
Editing the Calibration Coefficients).
