OPERATING INSTRUCTIONS
•
Liquid is seeping from the batteries.
•
The cables on the device are damaged.
•
Only use the device at ambient temperatures of -5 to +40 °C and a maximum
relative humidity of 85%. This is the only way to guarantee precise measurement
values.
•
In the case of loud background noise, make sure that the acoustic signal from
the device is audible.
Depending on the interior impedance of the voltage tester, in case of noise voltage
there are different options for the display "operating voltage available" or "operating
voltage not available".
•
A voltage tester with relatively low interior impedance will not display all noise
voltages with an original value above ELV compared to the reference value
100 kΩ. When in contact with the system components to be tested, the voltage
tester can temporarily lower the noise voltage by discharging down to a level
below ELV, however, after removal of the voltage tester the noise voltage will
resume its original value. If the display "voltage present" does not appear, we
strongly recommended that an earthing system is installed prior to commencing
work.
•
A voltage tester with relatively high interior impedance will not clearly display all
noise voltages with the noise voltage "Operating voltage not present" compared
to the reference value 100 kΩ. If the message "voltage present" is displayed for
a part that is considered detached from the system, we strongly recommended
that you use additional means (e.g. a suitable voltage tester, visual inspection of
the detachment point from the electrical grid, etc.) to verify the state "operating
voltage not present" of the system part to be tested and to determine that the
voltage displayed by the voltage tester is noise voltage.
•
A voltage tester that displays two values of interior impedance has passed
the test of its suitability for handling noise voltage and is capable (within the
technical limits) of differentiating operating voltage from noise voltage and
displaying the existing voltage type directly and indirectly.

Auto power on/off
The device and the measuring point illumination 3 switch off automatically after

Self test
The device has a self test function to ensure your safety. The self test verifies the
functioning of all LEDs on the LED display 13 , all symbols on the LC display 7 ,
the acoustic signal and the measuring point illumination 3 .
Carry out a self test prior to and following every use to ensure the
functionality of the device.
Proceed as follows:
Do not carry out voltage tests while the self test function is active!
1. Switch the device off by making sure that the test tips
L1- 14 and L2+ 2 are not receiving any signal. The device and the measuring
point illumination will switch off automatically after 30 s.
You can also manually switch off the device and the measuring point
illumination. To do this, press the [
2. Close phases L1- and L2+ by holding the two test tips L1- and L2+ to each
other.
All LEDs, all symbols on the LC display and the measuring point illumination are
illuminated. The acoustic signal is actuated for 3 s.
3. If all or individual LEDs as well as symbols on the LC display or the measuring
point illumination are not illuminated or the acoustic signal is not actuated, the
device cannot be used safely. Change the batteries (see section on „Replacing
batteries" on page 13) and restart the self test.
4. If the self test fails again, the device is not safe and may not be used. Contact
customer service (see section on „Service and warranty" on page 14).
