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 volt-
age 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 volt-
age range, the reading is displayed in volts and the “+~-” LED indicator lights
up. When the lower LEDs light up simultaneously, they indicate AC voltage.
A signal tone is emitted when exceeding the threshold value of 35 V. This
tone signals that a dangerous, life-threatening voltage is present!
Phase testing
Bring one of the probe tips into contact with a conductor, while touching the
finger contact located at the back. When a phase of min. 100V~ is con-
nected, the "<L" LED lights on.
When using finger contact to determine the phase wire, the perceptibility of
the display can be effected by several factors, including insulated mecha-
nisms that protect against direct touch, poor positioning (for example, on
wooden ladders or on insulated floor surfaces), an unearthed voltage, or un-
favourable lighting conditions.
