Max input current: 10A (less than 15 seconds).
Overload protection: 0.5A/250V fuse, 10A/250V fuse.
AC Current (ACA)
1. Insert the black test lead to “COM” input terminal and the red test
lead to “mA ”or “10A”input terminal,displayed as the picture.
2. Turn the function/range selection knob to current range, press
“SELECT”, switch to AC measurement mode, then 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. At the Manual Range mode,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.
Note:
a) Do not measure the current higher than 10A at Range 10A and
higher than 6000uA at uA Range and higher than 600mA 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.
