N
m. Variable RCD
n. RCD trip current (ramp test)
2. LCD Display
3. Function keys F1, F2, F3 and F4
4. TEST key
5. Test lead input (RED)
– Mains Live, Continuity/Insu
6. Test lead input (GREEN)
– Mains Earth, Continuity/Insulation -
7. Test lead input (BLUE)
– Mains Neutral
Note: Rotating the Rotary Switch through the off position
without stopping will maintain the power on the DL9120 /
DL9103EV.
Note: The DL9120 / DL9130EV will power off if it is inactive for a
period of time. In order to re-power the DL9120 / DL9130EV
you must rotate the Rotary Switch to off then rotate the
Rotary Switch to the required test position.
Note: The function performed by keys F1
– F4 depends upon the
rotary switch position. For each rotary switch position, the
left hand side of the LCD display indicates the function of
the key above.
