OPERATING INSTRUCTIONS
AC CURRENT MEASURE
1. Make sure that “Data Hold” button is no pressed.
2. Set Range Switch to the ACA 1000A range. If the
display indicates one or more leading zeros. Shift
to the 200A or 20A range to improve the
resolution of the measurement.
3. Press the trigger to open the transformer jaws
and clamp one conductor only it is impossible to
