Maintenance, Troubleshooting, and Calibration
An electrical shock hazard exists between the high
voltage supply and ground.
4.1 Maintenance and Troubleshooting
It is recommended that the following maintenance and troubleshooting procedures for the 190I:
Section 4.2 lists recommended spare parts.
Schematics, assembly drawings, and complete
parts lists are provided in the Appendix A.
1. Battery replacement as outlined in Section 1.5, Battery Installation/Replacement, when LOW BA
TTERY appears in the alphanumeric display and/or the audio low battery indication is activated.
If the LOW BATTERY message remains displayed
after replacing the batteries, contact Fluke
Biomedical for further instructions.
2. If a problem occurs with the printed circuit board, case, or audible alarm transducer, the suspect
part is easily replaceable. Refer to Section 4.2 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 1 for replacement procedures.
4. If the problem cannot be isolated or corrected using the above procedures, contact Fluke
Biomedical for further instructions.
