cracked or its metal elements are exposed.
p)
Take special care when a LED diode flashes or lights
up when indicating voltage.
q)
Correct LED indication is only guaranteed when is
performed in a temperature range of -10 ° C up to
55 ° C (<85% RH).
r)
Please observe general electrotechnical principles
and guidelines when taking measurements.
s)
Exercise caution when measuring voltage above 50V.
ATTENTION! Despite the safe design of the device
and its protective features, and despite the use of
additional elements protecting the operator, there is
still a slight risk of accident or injury when using the
device. Stay alert and use common sense when using
the device.

3.2. DEVICE USE
Automatic turning on/diagnostic test
•
Probes shorting automatically turns on the device
and activates the auto-diagnostic test mode.
•
If diode[5] is steady on, the battery voltage is normal.
•
If diode[5] flashes or is off, the battery voltage is <
2,4 ± 0,1 V.
•
The autodiagnostic test cannot be performed before
or after the use of the device, when the battery
voltage is low.
•
If the automatic shutdown does not work, replace
the batteries.
AUTO HOLD function
•
A currently displayed value will be present on the
display when the probes L1 and L2 are disconnected
from a measuring point.
Switching between DCV/ACV modes
To perform DCV measurements, when the device is locked
in ACV measurement mode, short the probes L1 and L2.
When 12V LED diode goes out, it means that the device is
ready to perform measurements.
Proceed in the same way if the device is locked in DCV
measurement mode and ACV measurement is needed.
If the device turns off automatically, ACV or DCV
measurements are possible to be performed directly after
starting the device.
Voltage test (Bipolar test)
Connect both probes to an object to be tested. The voltage
will be indicated by LED diodes and the LCD display.
The voltage polarity will be indicated in the way presented
on the illustration below.
When L2 probe is a positive (negative) potential , the
diodes will indicate „+ DC" („- DC").
The continuity test
WARNING! Make sure that a tested object is
disconnected from power supply.
The LED diode, which indicates circuit continuity [4], will
light up and the buzzer will beep continuously.
In the continuity test mode, the device works in the same
way as during the auto-diagnostic test.
Phase rotation test
Connect both probes to an object to be tested.
•
If the diode „L" lights up, the probe L2 is connected
to the line A and the probe L1 is connected to the
line B.
•
If the diode „R" lights up, the probe L1 is connected
to the line A and the probe L2 is connected to the
line B.
Turning the flashlight on/off
•
Pressing the [E] button will turn the flashlight on or
off.
•
Holding the [E] button for more than 2 seconds will
turn the backlight on or off.
Caution: The flashlight can be used when the device is
turned off. Using the flashlight shortens battery life.
Battery replacement
When a LED power diode [5] flashes or goes out during
the auto-diagnostic test. Follow the procedure below to
replace the batteries with new ones of the same type.
a)
Unlock the battery compartment [F] (the easiest way
to do this is to use a coin-shaped object).
Locked
Unlocked
b)
Remove the battery compartment and replace
the batteries. Insert new batteries following the
indications.
c)
Insert the battery compartment back into the device
and twist it to the „locked" position.
WARNING: Make sure that the battery compartment
is properly locked before using the device.
3.3. CLEANING AND MAINTENANCE
a)
Use only non-corrosive cleaners to clean the surface.
b)
After cleaning the device, all parts should be dried
completely before using it again.
c)
Store the unit in a dry, cool place, free from moisture
and direct exposure to sunlight.
d)
Do not spray the device with a water jet or submerge
it in water.
e)
The device must be regularly inspected to check its
technical efficiency and spot any damage.
f)
Do not leave the battery in the device if it will not be
used for a longer period of time.
g)
Use a soft, damp cloth for cleaning.
