Maintenance, Repair and Calibration
5.1 Maintenance
The only maintenance necessary for this instrument is battery removal and replacement
5.2 Battery Replacement
The battery holder is located in the instrument rear, just below the carrying handle.
Remove the two thumbscrews holding the battery compartment cover in place by turning them in a
counter-clockwise direction until the cover plate can be removed from the case. Replace the batteries as
shown in Figure 2-1 making sure that polarity is correct. Then replace the cover plate using the
thumbscrews. Ensure that the cover plate is
snug.
The battery cover plate must be flush and snug
against the outer surface of the case. This is to
ensure proper battery contact with the spring-
loaded contact block in the battery compartment.
5.3 Repair & Calibration
Due to the sensitive nature of this instrument, it should be returned to the factory for repair and
calibration.
