Figure 6-1. Accessing the Fuse
6-3. Cleaning the Air Filter
Caution
Damage caused by overheating may occur if the area around
the fan is restricted, the intake air is too warm, or the air filter
becomes clogged.
The air filter must be removed and cleaned every 30 days, or more frequently if the
calibrator is operated in a dusty environment. The air filter is accessible from the rear
panel of the calibrator.
To clean the air filter, refer to Figure 6-2 and proceed as follows:
1. Turn off the POWER switch and disconnect the line power cord from ac line power.
2. Squeeze together the sides of the air filter housing and pull it off.
3. Wash the filter element and housing in soapy water.
4. Rinse the filter element and housing in fresh running water.
5. Shake out excess water, then allow the filter element to dry thoroughly before
reinstalling it.
6. Snap the filter housing back into place.
