1. Please read out this manual thoroughly before using the meter.
2.Do not use the instrument if testing leads or the meter being damaged.
3.Do not connect electrical conductor which over DC60V,AC36V RMS, it has reached the electric shock limit.
4.Cut off the electric power before measuring the resistance.
5.Meter storage should not under high temperature environment,direct sunlightwill shortened lifespan of the LCD.
6.Please replace the batteries while low power symbol””displayed.Take out the batteries in time before long time storage, batteries leakage will damage the meter.
7.Do careful when measuring with bare wire.
8.When power feed with outer adaptor, inner batteries supply will automatically cut off and no charging.Attention: please select for +— power mode.
9. Ground resistance test requirements:
- a. AC connect, earth resistance should not over 4Ω;
- b.Safe connect, earth resistance should not over 4Ω;
- C. DC connect, earth resistance value depend on detailed system requirements.
- d. Earth resistance forplace of lighting-protection should not over 10Ω;
- e. Jointgrounding for shielding system, earth resistance should not over 1Ω.
