DL9120 / DL9130
Operating Instructions
- 19 -
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.
The DL9120 / DL9130EV will display the Test Lock and battery symbol
for 1 second. If the Test Lock feature is required, it should be activated
as described below.
Functions keys F1-F4 have are used to select the options below:

Buzzer (F1)
When enabled, the Buzzer will sound when the continuity measurement
is less than or equal to 1M
ohm
.
Test Lock (F3)
The Test Lock is used to ‘lock’ the DL9120 / DL9130EV in a continuous
measurement mode, with a single press of the TEST key. When Test
Lock is enabled, the LCD shows the padlock icon. When Test Lock is
active the TEST key is locked until the option is disabled or the rotary
switch is moved to another position.
To enable the Test Lock mode, press the F3 key before the TEST key is
pressed or press F3 and the TEST simultaneously.
To disable Test Lock, press F3 or turn the rotary switch to another
position.
TEST
To make an insulation resistance measurement, press the TEST key.
When a single press is made, the test will start for a duration of 3 seconds.
If the TEST key is held down, the test will continue until the TEST button
is released. Alternatively, use the Test Lock function to allow
