4.2 Resettable Job Timer (JOB)
The resettable job timer (JOB) allows you to track the operating time for a specific work period. This value can be reset as needed, making it useful for monitoring individual tasks or maintenance intervals. The JOB timer range is also 0 to 99,999 hours.

The device includes a built-in CR2430 battery with a long standby time. The battery is not user-replaceable.
6. Troubleshooting
- Inaccurate Hour Readings: If the meter is not accurately recording hours, adjust the programmable sensitivity setting (Low/Medium/High) to match the vibration frequency of your equipment. Refer to section 4.4 for details.
- Display Not Activating: Ensure the equipment is generating sufficient vibration for the meter to detect. Check if the display lock function (Loc) is active, which can prevent the display from showing hours.
- Low Voltage Reminder: The meter will display a 'b-Lo' reminder when the battery voltage is below 2.7V, indicating a low battery status.
