II. Safety Notices
This instruction manual contains information that must
be followed for operating the meter safely and main-
taining the meter in a safe operating condition. If this
meter is not used in the manner that is specied, the
protection provided may be impaired.
Warning! Warns of potential danger, refer to the
instruction manual to avoid personal injury or damage
to the meter.
Caution! Dangerous voltage. Danger of electrical
shock.
Perfect display is only guaranteed within a temperature
range of -10 - 50°C, relative humidity <85%.
A statement about protection impairment if used in
a manner not specied by the manufacturer.
The voltage indicators are designed to be used by
skilled persons and in accordance with safe methods
of work.
The voltages marked on the voltage indicator are
nominal voltages and the voltage indicator is only to
be used on installations with the specied nominal
voltages.
The dierent indicating signals of the voltage indicator
are not to be used for measuring purposes.
Before using a voltage indicator at locations with a
high background noise level, it has to be determined
whether the audible signal is perceptible.

II. Safety Notices (continued)
It is important to check the state of the battery before
use and to replace it if necessary.
The meter has been designed in accordance
with the safety regulations for electronic
measuring instruments, EN 61010-1:2010,
EN 61010-2-030:2010, EN 61010-031:2015, EN
61243-3:2014, EN 61326-1:2013 & EN 61326-
2-2:2013
Voltages above 75V DC or 50V AC may constitute a
serious shock hazard.
Before using the meter, check for physical damage to
the casing, in particular around the cable strain relief.
If the case is damaged, do not use the meter.
Check the test probes for damaged insulation or
exposed metal.
Check the leads for continuity.
Do not apply more than the rated voltage, as marked
on the meter between the terminals or between any
terminal and ground.
Do not use or store the meter in an environment of
high temperature, humidity, fumes, vapour, gaseous,
inammable, and strong magnetic eld.
The performance and safety of the instrument and the
user may be compromised in such circumstances.
Disconnect circuit power and discharge all high voltage
capacitors before testing resistance, continuity and
diodes.
Remove the batteries if the meter is not in use for a
long period.
Constantly check the battery as it may have leaked. A
leaking battery will damage the meter.
The meter may only be opened by a qualied service
technician for calibration and repair.

1. Operating Instructions
Carrying out measurements
Perform a self-test of the unit. Connect the two
test probes L1 and L2 together. The continuity
LED (6) will be lit, and an audible tone should be
heard.
Before any test, check the unit on a known
voltage source or approved voltage proving unit.
If the unit is defective it should be put out of service
and returned to Di-LOG for repair.

Always hold the test probes by the handles
behind the nger guards. Observe all the safety
notices at all times.
An audible tone is present when an AC voltage
and a negative DC voltage are indicated.
The maximum switch on time is 30 s. When this
time has elapsed, you must wait 10 minutes
before retesting.
Connect probes to the voltage source observing
the polarity of the test probes, L2 is the positive
probe, L1 is the negative probe.
For AC voltage the value is indicated on the
LEDs (3) and on the LCD display (DL6790 only).
The + and - LEDs are illuminated and buzzer is
audible.

3. DC Voltage Indication
For DC voltage measurement, connect probe
L2 to the positive terminal and L1 to the negative
terminal. The voltage is displayed on the LEDs
and the LCD display (DL6790 only). The positive
LED (10) is illuminated. If the polarity is reversed
the buzzer will sound. The negative LED (11) will
be illuminated.
