1) Before measurement, cut off the power of object to be measured and inspect
whether input terminal or rotary switch is set to the proper range. Ensure it is
proper, then you can measure the object with power on.
2) 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.
3) Measuring value inputs from “
V
Ω
mA” or “10A” jack (red test leads) and “COM”
jack (black test leads).
4) For “
V
Ω
mA” input jack, the Meter has a 0.5A/250V (
φ
5x20mm) fuse,
overloaded,if overloaded, the fuse will be melt up, so replace with a new one
with the same specification.
5) 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.
6) The meter would clatter with glitter of LCD reading if input exceeding 1000V,
or overloaded which warns you pay extra attention.
7) The meter would clatter with glitter of LCD reading if overloaded, which warns
you pay extra attention.
