DL9120 / DL9130
Operating Instructions
- 28 -
Equipment which is connected downstream of a residual
current protective device (RCD) may cause a considerable
extension of the operating time.
The DL9130EV will determine the fault voltage that may
appear on the protective conductor during the test. If the
fault voltage is greater than 25V the DL9130EV will indicate
>25V on the LCD, but the user may proceed with the test.
If the fault voltage is great than 50V, this is indicated on the
LCD and the test is inhibited.
The Auto test is used to automatically perform a sequence of RDC-DD &
RCD trip time tests with a single press of the TEST key. Each time the
RDC-DD or RCD trips, the sequence will automatically continue once the
RDC-DD / RCD is reset.

Switches between RCD and EV mode (F1, DL9103EV only)
This switches the DL9103EV between the standard RCD auto test
sequence and the EV auto test sequence.

Recall (F3)
The RCL (Recall) key is used to recall the results of the last automatic
RCD test performed by the DL9120 / DL9130EV. The LCD will update to
show all of the relevant parameters for the result displayed. Repeat press
the F3 key to cycle through the results.
Pressing any key while displaying a recalled measurement will return the
DL9120 / DL9130EV to the normal pre-test screen.

The test current can be selected by pressing the F4 key. Repeat press
the F4 key until the desired RCD test current is displayed. The only
options available are 6mA for RDC-DD or 30mA for RDC Type B.
