Frequency response: 40-400Hz. Indication: average value response (RMS of sine wave). Duty Circle
indicaton (0.1%-99.9%)
1.
Insert the black test lead to “COM” input terminal and the red test
lead to “uAmA” or “10A”, the max input current value is respectively
400mA and 10A, display as the right picture.
2.
Turn the function/ range selection knob to current range, press
“SELECT”, switch to DC measurement mode, then connect the test
with the tested circuit in series, the polarity of the red test lead and
the tested current value will be displayed om LCD simultaneously.
3.
If “OL” is displayed on LCD, it indicates the tested current value
has exceeded the present range limit, please select the higher range
to complete the measurement.
a.
Do not measure the current higher than 10A at Range 10A higher
than 400uA at uA Range and higher than 400mA at mA Range,
otherwise the fuse will be burnt out or the instrument will be
damaged.
b.
Do not connect the test lead to any circuit in parallel when the
test lead is inserted in the current input terminal, otherwise it is
possible to damage the instrument or endanger the safety of the
users. Cut the connection between the test lead and tested circuit
at once after measurement.

1.
Insert the black test lead to “COM” input terminal and the
red test lead to “uAmA” or “10A” input terminal, displayed as
the right picture.
2.
Turn the function/range selection knob to current range,
press “SELECT”, switch to AC measurement mode, than
connect the test lead to the tested circuit in series,
the polarity of the red test lead and the tested current value
will be displayed on LCD simultaneously.
3.
If “OL” is displayed on LCD, it indicates the tested current
value has exceeded the present range limit, please select the
higher range to complete the measurement.
