Remarks:
s
In current measurement, the internal resistance of
the current range is placed in series and the
current drops by this resistance. Accordingly, its
influence becomes larger in low-resistance circuits.
s
The AC accuracy guarantee frequency range is
from 40 Hz to 400 Hz.
s
Current range: Auto range for 400.0 μA ~ 4000 μA
and 40.00 mA ~ 400.0 mA. The range can be
fixed by the RANGE HOLD button.
1. Never apply a voltage to the measuring terminals.
2. Never apply an input exceeding the maximum rated current.
3. Be sure to connect the meter in series via a load.
WARNING
Be sure that the built-in fuse has not blown.
