Remarks:
• 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.
• The AC accuracy guarantee frequency range
is from 40 Hz to 400 Hz.
• Current range: Auto range for 400.0 µA 4000
µA, 40.00 mA 400.0 mA and 4.000 A
10.000 A. The range may be fixed by the
RANGE HOLD button.
