PROBLEMS WITH THE MODEL 35080M KVP DIVIDER
1. The power battery may be weak or dead.
Check the battery and replace it if necessary (see Section 2.2, Battery Check, and Section 9.3,
Battery Replacement).
2. The function switch on the Model 35080M kVp Divider may be in the wrong position, such as “CAL”.
Verify that the function switch is in the “RUN” position.
3. Orientation of the kVp divider may not be correct for the location of the X-ray source.
(Refer to Section 2.5, Geometry of Setup.) Turn the kVp divider upside-down for under-table X-ray
heads and right side up for above-table X-ray heads.
4. There may be an electronic fault in the kVp divider.
Check the CAL operation of the kVp divider (refer to Section 2.3, Internal Calibration Check).
9.3 Battery Replacement
The Model 35080M kVp Divider is powered by a single 9 V Eveready type 522 alkaline battery. Battery
life is approximately 50 hours. The battery condition can be checked without opening the instrument
case; with the function switch in the “CAL / BAT CHK” position and the power button depressed, verify
that the LED indicator is green.
Do not leave the function switch in the “CAL /
BAT CHK” position, as this will decrease
battery life.
If the battery voltage drops below 7.0 V, the LED indicator will become red and the battery should be
replaced, as the remaining life of the battery is quite limited. If the battery voltage is already below 6.5
volts when checked, the battery must be replaced for proper operation of the kVp divider.
To replace the battery, remove the screw from the cover on the bottom of the kVp divider (refer to Figure
9-1). Lift the cover from the instrument case. Place your hand over the battery compartment and roll the
instrument upright, letting the battery drop into your hand.
Carefully remove the used battery and replace it with a fresh 9 V alkaline battery (Eveready type 522).
Slip the battery back into the compartment and replace the cover. Note that the tabs of the cover must be
inserted under the lip of the instrument case before it is properly seated (refer to Figure 9-1). Align the
hole in the cover with the threaded hole in the case and reinsert the screw.
Install the new battery as shown on the polarity
sticker.
