temperatures of between -10 °C and
+50 °C.
Keep the device clean and dry at all times.

The casing may be cleaned by wiping with
a damp cloth.
The additional warning symbols and
|
acoustic signals issued when voltages are
greater than 35 V are only intended to warn
of the danger of life-threatening voltage.
They should not be used for measurement
purposes.
Check to make sure that the warning tone

can be heard amidst the local ambient
noises.

General points

Voltages have priority. If no voltage is detected at the probe tips (< 3.0 V), the
device is in continuous testing mode. To switch the led torch please press the button
"light".

Self-test

Hold the test leads to one another for the test. The buzzer on the test device should
sound clearly and the display should show the green "Rx/Ω". (After a short time the
instrument is automatically turned off by the "auto-power off" function.) If the LED
is blank or dimly illuminated, the batteries must be replaced.
If the instrument does not operate with new batteries, then it should not be used.

Testing DC voltage

(Hold the test tips together in order to switch on.)
When the probe tips are connected to a DC voltage within the nominal voltage range,
the reading is displayed in volts and the (12V +~-) LED indicator lights up. The
lower LEDs indicate the polarity according to the labelling on the probe tips! (+, -)
A signal tone is emitted when exceeding the threshold value of 35 V. This tone
signals that a dangerous, life-threatening voltage is present!

Testing AC voltage

When the probe tips are connected to an AC voltage within the nominal voltage
range, the reading is displayed in volts and the "+~-" LED indicator lights up. When
the lower LEDs light up simultaneously, they indicate AC voltage.
