6 Instrument Description

6.1 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 button "light".
6.2 Self testing:
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/Ώ". (After a short time the
instrument is automatically turned of 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.
6.3 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
LED-s indicates the polarity according to the labelling on the probe tips! (+ , -).
