18. Repeat steps 13 through 17 until equal readings on either side of 190.0 are attained on the Model
35035 display.
19. Turn the Model 35035 RANGE switch to the 2000 position.
20. Apply +1000 mA for 1.9 seconds to the Model 35035 input and verify that the display reads
between 1895 and 1905.
21. Depress the RESET button.
22. Apply -1000 mA for 1.9 seconds to the Model 35035 input and verify that the display reads between
-1895 and -1905. Before depressing the RESET button, verify that the display drifts no more than 5
display counts over a period of one minute.
23. Depress the RESET button.
24. Place the MODE switch in the AC position.
25. Again apply -1000 mA for 1.9 seconds to the Model 35035 input and verify that the display now
reads between 1895 and 1905. This verifies correct operation of the front-end rectifier circuit in the
Model 35035.
26. Depress the RESET button, place the MODE switch back in the DC position, and turn the RANGE
switch to the 20 position.
27. With the Model 35035 FUNCTION switch still in the mAs position, apply +100.0 mA to for 1.9
seconds to the input and verify that the display reads 0.00. This verifies lockout of the 20 range in
the mAs function.
28. Turn the RANGE switch of the Model 35035 to the 2000 position and the FUNCTION switch to the
OFF position. With the current source output turned off, remove the test leads from the Model
35035 input terminals. This concludes the adjustment and operational checkout of the meter.
4.6 Battery Replacement
The Model 35035 meter operates on a standard 9 V alkaline battery such as the Eveready 522. A +
appears in the display when the battery voltage reaches 7.2 V, indicating the battery needs to be
replaced. The use of a battery type other than alkaline is not recommended.
To avoid electrical shock, the instrument must be
disconnected from the x-ray generator.
1. Turn the meter OFF and remove the test leads.
2. Turn the instrument over and remove the battery compartment cover.
3. Grasp the battery clip leads near the clip, gently lift the battery out of the compartment, and remove
the old battery from the clip.
4. Install the new battery. Be certain that the clip end of the battery is inserted at the end of the
compartment where the clip wires come out from the case and that the wires get looped around the
top of the battery. This will aid the user the next time the battery needs to be replaced.
5. Re-install the battery compartment cover.
