3) If the magnitude of current is unknown, you should set rotary switch

to the higher range, then adjust to a lower range until a satisfactory

reading is obtained.

4) Measuring value inputs from “V

mA” or “10A” jack (red test leads)

and “COM” jack (black test leads).

5) For “V

mA” input jack, the Meter has 0.5A/250V ( 5x20mm) ceramic

fuse overload protection, if overloaded, the fuse will burn up, so replace

with a new one with the same specification.

6) For 10A input jack, it is unfused. For your safety, every measuring time

should equal to or less than 10 seconds, times interval should be equal

to or over 15 minutes.

7) The meter would clatter with glitter of LCD reading if input exceeding

1000V or overloaded, which warns you pay extra attention.
