IX. Notes
1. After testing, please charge the battery in time.
2. During DC test, if the undervoltage indicator light became
bright, please use AC power instead of DC power for test.
3. If the instrument will not be used in long-term, please charge
up the battery regularly (two months) until the "full" indicator lights
up, generally charge time is about 6 hours.
4. You should prevent the instrument damp, falling, and
exposure.
