To prevent wrong connection of test leads and to maintain safety, the
dedicated terminals used for continuity and insulation tests are automatically
covered when using the terminals for loop impedance and RCD tests

Illuminates if there is an alternating voltage of 20V
AC or more in the circuit under test before
continuity or insulation resistance tests. When DC
voltage is detected across the measuring terminal
the LED lights up.
The P-E and P-N LEDs illuminate when the wiring
of the circuit under test is correct. The
reverse
lamp is lit when P and N are reversed.
Auto data hold
In the loop impedance and RCD test functions, the
LCD reading is automatically frozen for 5 seconds
after measurement.
