Caution:
• Do not input a voltage over 1000 V or it may damage the meter.
• Take care to avoid electric shock when measuring high voltages.
• After completing the measurement, disconnect the test leads from the circuit under test.
• Before each use, verify meter operation by measuring a known voltage.
• After using the LoZ function, wait 3 minutes before next operation.
• LoZ ACV measurement eliminates ghost voltage for more accurate measurement.
