Service
Have a qualified technician calibrate the Analyzer once a
year. We recommend that you send the Analyzer to a
Fluke service center for calibration or service.
Battery
The Analyzer uses a 9-volt, non-rechargeable alkaline
battery. Refer to Figure 13 for battery replacement
instructions.
If battery voltage drops too low, the message “Warning
Your Battery Is Low” appears on the screen. Press G
(Ok) to resume viewing the previous display. The
Analyzer will now occasionally beep and eventually
display the warning screen again, allowing you to repeat
the process. However, to maintain accurate
measurements, replace the battery as soon as possible
after the first warning you notice.
Press S Æ C Æ E to check the battery level.
