(F1)
Use the F1 key to alternate between the starting angle of the current. All
RCD tests will start on zero crossing. For type B RCDs 0
o
will perform
positive dc tests and for 180
o
negative dc tests.
RCD Type (F2)
Function key F2 is used to select the required RCD type: AC, DC sensitive
and pure DC combined with standard or selective RCD types. Each time
the F2 key is pressed the next option is selected
RCD Type AC (Sinusoidal Waveform)
RCD Type AC Selective (Sinusoidal Waveform)
RCD Type A (Pulsating Waveform)
RCD Type A Selective (Pulsating Waveform)
RCD Type B (DC)
During selective tests the DL9120 / DL9130EV will display a delay timer
which counts down from 30s to 0s. Pressing the Test key or turning the
rotary switch while the DL9120 / DL9130EV is counting will terminate the
count.
Variable Current (F3)
Function key F3 is used to select the variable RCD current function. The
RCD current is set using the Variable RCD function and cannot be altered
in this mode.
