4. Operating Instruction
- If the current under measurement is higher than the selected value for a long
period, overheating may take place, compromising the safety and operation of inner
circuits.
- Do not measure currents on high-voltage conductors (>600V) to avoid risks of
discharge and/or incorrect reading.
AC current measurement
Make certain that all test leads are disconnected from the meter terminals.
- Set function switch to A range.
- Press AC/DC key to select AC function
- Clamp the current transducer (jaw) around one of the conductors under test.
Make sure that the clamp jaw be perfectly closed.
- Read the display value.
