Maintenance - Fluke Victoreen 190 Operator's Manual

4.1 Maintenance

Fluke Biomedical recommends the following maintenance and troubleshooting procedures for the Model
190:
1. Battery replacement as outlined in Section 3 - "Operation" when LOW BATTERY appears in the
alphanumeric display and/or the audio low battery indication is activated.
2. If a problem occurs with the printed circuit board, case, or audible alarm transducer, the suspect
part is easily replaceable. Refer to Table 4-1 for a list of Replacement parts.
a. The printed circuit board has all but the PROM, RAM, and the microprocessor soldered into the
board.
b. The case and modules are molded plastic and may require replacement due to contamination.
c. The speaker and its gasket are open to the surface of the instrument, to allow audible
indications to be clearly heard, and may therefore require replacement due to contamination.
3. If the problem is isolated to the probe or module, refer to Section 3 - Operation for replacement
procedures.
4. If the problem cannot be isolated or corrected using the above procedures, contact Fluke
Biomedical at 440.248.9300 for further instructions.
Table 4-1 lists recommended

after replacing the batteries, check the detector
high voltage (RP3) as outlined in Section 3 -
"Operation". If the message is still displayed,
contact Fluke Biomedical at 440.248.9300 for
