Charging Precautions
1. The meter can be powered by both AC and DC, but when the on-site power supply has significant interference or is unstable, it is recommended to use battery power.
2. When using the rechargeable battery for the first time, it needs to be charged for more than 6 hours. Otherwise, the meter will not work properly.
3. The charging circuit uses a dedicated intelligent charging management module, which can automatically stop charging.
Note: The AC input voltage range of the charging adapter is 220V±15%, to avoid unnecessary losses due to incorrect power connection.
4. Insert the DC end of the charging adapter into the meter's power jack ⑨, connect the other end to AC power, the charging indicator light (red) will turn on, and fast charging begins.
5. When the battery is nearly fully charged, the charging indicator light (green) will turn on, switching to trickle charging. After a period of time (1-2) hours, you can unplug the plug to stop charging and start using the meter.
Note: When the meter is not in use, ensure the band switch is in the off position to prevent the battery from draining prematurely.
The speed of the hand-cranked megger should be maintained at 120r/min.
