Indicates the selected rotary switch setting. The measurement value in the
primary display also corresponds to the switch setting. Rotary switch settings are:
Insulation RCD trip time
Continuity RCD trip current
Loop no trip Earth
Loop hi current trip Phase Rotation
26
Indicates the preset fault voltage limit. The default setting is 50 V. Some
locations require the fault voltage be set to 25 V, as specified by local electrical
codes. Press F4 when you turn on the tester to toggle the fault voltage
between 25 V and 50 V. The value you set will appear on the display and will be
saved when you turn the tester off.
