5.3 Continuity Tests
Always ensure that the circuit under test is electrically
isolated.
Measurements can be adversely affected by impedances
of additional operating circuits connected in parallel or by
transient currents.
If the test probes are connected across a voltage of >30V
ac/dc then the DL9120 / DL9130EV will automatically
display the voltage between the probes, the warning buzzer
will sound.
Rotate the rotary switch until the Continuity test is selected.
When the continuity test is selected, the DL9120 / DL9130EV will display
the user selectable test options for a short period of time; Buzzer, R max,
Lead Zero and 15/200mA (15mA DL9130EV only). If the Buzzer or Lead
Zero was previously enabled, then the icon will remain on the display
when the continuity test is selected. If the Lead Zero is disabled then the
icon will flash to indicate that the leads should be zeroed, if the Buzzer or
R max are disabled then the icons will not be displayed.
Functions keys F1-F4 have are used to select the options below:

icon is shown on the display. All subsequent measurements will
automatically include compensation for the test lead resistance. To
disable the function, remove the leads from the load to measure open
circuit, press and hold F3.
Note: A maximum test lead resistance of 10 ohms can nulled out. If
the test lead resistance is greater than 10 ohms an error beep
will indicate that the Lead Zero function has failed, and the
display icon will not be shown.
Note: For ease of use, the DL9120 / DL9130EV will store the Lead
Zero compensation when switched off and recall this value
when next switched on. The stored value is only applicable to
the test leads used when the compensation measurement was
made. If the test leads are replaced the Lead Zero function
should be repeated using the replacement test leads.
200mA / 15mA Test Current (F4, DL9130EV only)
The DL9130EV can perform Continuity tests at both 200mA and 15mA.
To switch between the currents the test probes must be open circuit.
Press F4 until the required test current is displayed.
The DL9120 can only perform tests at 200mA.
TEST

button, the test will automatically start when a low resistance is detected.
5.4 Insulation Resistance Tests
Always ensure that the circuit under test is electrically
isolated.
Should a voltage of >30V be applied to the DL9120 /
DL9130EV while in Insulation mode the DL9120 /
DL9130EV will enter Voltage mode until the voltage is
removed.
If the test probes are connected across a voltage of >30V
then the DL9120 / DL9130EV will automatically display the
voltage between the probes, the warning buzzer will sound

The DL9120 / DL9130EV will discharge any charged
voltage that has been generated due to the insulation test
as long as the DL9120 / DL9130EV remains connected to
the circuit under test after the test is complete. If the
charged voltage is hazardous at the end of the test the
DL9120 / DL9130EV will enter voltage mode until the
voltage is below 30V.
Should the DL9120 / DL9130EV be removed from the
circuit under test during an active Insulation test then any
charged voltage CANNOT NOT be discharged by the
DL9120 / DL9130EV.
Use the rotary switch to select either the 250V, 500V or 1000V M
(DL9130EV only) test.

display the voltage will also be indicated on the LCD.
When a 3 phase voltage is connected to the test probes, the voltage
between the red and black is displayed in the primary display and the
phase sequence icon is shown on the display. When the test probes are
connected as follows: RED to L1, GREEN to L2, BLACK to L3 the display
icon will show L1 L2 L3.
5.6 Single Phase High Current Earth Loop Impedance /
Line Impedance
The DL9120 / DL9130EV will only allow the Earth Loop
Impedance test to be performed if the correct voltages are
detected between line-earth (L-PE illuminated), line-neutral
(L-N illuminated) and neutral-earth (N-PE not illuminated).
When performing 2 wire tests and under certain
circumstances, a potential hazardous touch voltage could
be determined due to the impedance of the circuit under
test, the DL9120/9130 will stop the test immediately
indicating “3 LEAd”. If this happens, connect all three
Page 21

Auto Start
The DL9120 / DL9130EV is capable of performing both 2 wire and 3 wire
High Current Loop / Line Impedance tests on single phase installations.
In order to perform 2 wire tests the correct connection setting (F1) must
match the 2 wire connection being made.
For two wire Line Impedance the connection setting (F1) must be set to
L-N and the red and blue must be connected to live and neutral
respectively.
For two wire Loop Impedance the connection setting (F1) must be set to
L-PE and the red and green must be connected to live and earth
respectively.
In 3 wire mode the test will be performed to the L-N / L-PE setting, all
three live to red, neutral to blue and earth to green connections must be
made.
If the DL9120 / DL9130EV is set to auto-start as soon as the correct
connections are made the test will start.
Note: Connections must not be changed (removed or added) when
active tests are being run.
Tip: If the DL9120 / DL9130EV is set in Auto mode you can change
connection method in between tests. By always connecting
the Live (Red) connection last this will stop the test starting
while you may still be connecting the earth or neutral
connection for a 3 wire test.
Note: When performing 2 wire tests should a potential hazardous
touch voltage be determined due to the impedance of the
circuit under test, the DL9120 / 9130EV will stop immediately
indicating “3 LEAd”. If this happens connect all three
connections to the system under test before retrying the test.

5.9 Auto RCD Test Sequence
The DL9120 / DL9130EV will only allow the RCD test to be
performed if the correct voltages are detected between lineearth (L-PE illuminated), line-neutral (L-N illuminated) and
neutral-earth (N-PE not illuminated).
Potential fields from other earthing installations, large
voltages between the protective conductor and earth, large
voltage between the neutral and earth or leakage currents
in the circuit following the residual current protection device
may influence the measurement.
Equipment which is connected downstream of a residual
current protective device (RCD) may cause a considerable
extension of the operating time.
The DL9120 / 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 DL9120 /
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 RCD trip
time tests with a single press of the TEST key. Each time the RCD trips,
the sequence will automatically continue once the RCD is reset.
