8 Maintenance or Repair
1. When the When symbol is displayed on the LCD, it
means that there is insufficient power; please change the
battery immediately in order to ensure its accuracy.
2. Do not place the meter in locations that have high
temperature, humidity or that are exposed to direct
sunlight.
3. Remember to turn off the power after usage; remove the
battery if not used for a long period of time in order to
prevent battery leakage and causing damages to internal
components.
When the instrument failure, only by the authorized service
provider or return the original repair.
