Service
3-4
Operator maintenance 3-3.
Warning
To avoid electrical shock, remove the test leads before opening
the case, and close the case before operating the meter. To
prevent fire, install fuses with the rating shown on the back of
the meter.
Caution
To avoid contamination with oil from the fingers, handle the pca
by the edges or wear gloves. PCA contamination may not cause
immediate instrument failure in controlled environments.
Failures typically show up when contaminated units are
operated in humid areas.
Case Disassembly 3-4.
Use the following procedure to disassemble the case:
1. Set the function switch to OFF and disconnect the test leads if they are installed.
2. Remove the four Phillips screws from the bottom case.
3. Turn the meter face up, grasp the top case, and pull the top case from the meter.
Battery Replacement 3-5.
The meter is powered by a single 9V battery (NEDA 1604, 6F22, or 006P).
Refer to Figure 3-1, and use the following procedure to replace the battery:
1. Remove the top case as described under Case Disassembly.
2. Lift the battery from the case bottom and install the new battery.
3. Reinstall the top case and the four Phillips screws into the bottom case.
Fuse Test 3-6.
Use the following procedure to test the internal fuses of the meter.
1. Turn the rotary selector switch to the Ω  position.
2. Plug a test lead into the VΩ input terminal, and touch the probe to the 10A input
terminal.
3. The display should indicate between 0.1 and 0.5 Ohms. This tests F2 (15A, 600V). If
the display reads OL (overload), replace the fuse and test again. If the display reads
any other value, further servicing is required.
4. Move the probe from the 10A input terminal to the 40 mA input terminal.
5. The display should read between 10 Ohms and 12 Ohms. This procedure tests F1
(1A, 600V). If the display reads a high resistance or OL (overload), replace the fuse
and test again. If the display reads any other value, further servicing is required.
