To prevent damage to the device from leaking batteries, remove the batteries from the device if
you will not be using it for a longer period. For the same reason, we recommend that you remove
flat batteries immediately.
Function test / Self test:
•
Test the voltage tester on a known source.
•
Warning: To avoid electric shock, disconnect the test leads from any source of voltage before turn
on the self-check test function.
•
The “!” LED will light on when there is a voltage over 50V, even if the battery is low or if the
battery has been removed.
•
When press “Autotest” button, all the bargraph will must be light on, and LCD display “000” ,and
The continuity test’s LED (6) will light on, buzzer sound. This shows the tester self-test was done.
Measuring Point Lighting
The voltage tester has a battery-operated measuring point lamp. Press button (8) to switch this
lamp on. The lamp stays on
as long as this button is kept pressed. When the button is released, the lamp goes off.
Carrying out Measurements
The twin-pole voltage tester has two handles, a connecting cable and an LCD display. Always hold
the voltage tester in such a way that you get a vertical view of the display. Strong incidence of light
may have an adverse effect on the display. For DC measurements, test tip is the positive pole,
and the test tip is the negative pole.
Before each voltage measurement, check that the device is working properly by measuring a known
voltage source. If the tester’s LCD display remains blank, take the voltage tester out of operation.
A defective voltage tester must not be used. Do not operate the device with flat batteries or
without batteries. Observe the regulations regarding work with electrical systems.
The device can be used for the following types of measurement:
Voltage measurement with high internal impedance
Always hold the voltage tester by the handles designed for this purpose. Never touch the device
beyond the handle ends. Hold the two test tips onto the measuring points to be tested. The voltage
tester switches on automatically with voltages higher than 4.5V AC/DC. The voltage measured is
shown on the LCD display. If the measured voltage falls below 4.5 V AC/DC, the voltage tester
switches off automatically.The LCD display shows the voltage values numerically and in the form of
a bargraph. The type of voltage (alternating current = AC or direct voltage = DC) and the polarity
are also shown on the LCD display. In the event of negative DC voltage, the numeric voltage value is
preceded by „ - „. Positive DC voltage is shown without a positive sign preceding the value.
