Safety information
You have chosen an instrument providing a high degree of safety. To ensure safe and correct application, it is necessary to fully
read this operating manual before using the instrument for the first time.
The following safety precautions apply:
Perform a function check of the voltage tester immediately before use (VDE regulation
|
0105, Part 1). Make sure that the test line and instrument are fully operable. Check the
instrument on a known source of voltage, e.g. 230 V socket.
If the display fails to indicate one or more functions, then do not continue to use the in-
|
strument. It must be checked by a specialist.
Only hold the instrument on the handles (3) below the mechanical mark (2), avoid
|
contact with the test probes (1)! (Refer to the figure)
| Only perform tests for isolation from the power supply on both poles!
| The instrument must not be operated in a humid environment!
| Do not use with the battery compartment open! Whilst replacing the battery, the test
probes must be removed from the test circuit.
| A correct display is ensured in the temperature range of -5 °C to +40 °C.
| Always keep the instrument dry and clean. The housing should only be cleaned using
a damp cloth.
| The additional warning symbol displayed and the tone for voltages > 50 V AC / 120 V
DC are only to warn of life-threatening voltages and are not for test purposes!
Immediately replace the batteries if a warning signal sounds shortly after switching on
|
the instrument, or when the instrument is switched on and immediately switches off.
The various signals of the voltage tester (including the ELV limit value) displayed must
|
not be used for test purposes.
General
Voltages have priority. If no voltage is applied at the test probes (< 6 V), the instrument is in the continuity test mode.
Function
To switch on the appliance simply press the light button or hold the probes together.
Attaching and removing the adapter for the test probes makes it easier to carry out tests at the socket.
Self-Test / Auto Power-Off
When initially switching on, either when inserting a new battery or when the test probes are held on one another if the instrument is
off, all optical displays (LEDs) illuminate and a signal sounds. Shortly after, the instrument changes to continuity testing.
If the display fails to indicate one or more functions, then do not continue to use the instrument. It must be checked by a specialist.
For the test, hold the test probes together to ensure the instrument is in operating state. This should be carried out immediately be-
fore and after use. If the LEDs do not illuminate or only faintly, replace the batteries. If the instrument does not function with new
batteries, it must be protected from being used incorrectly. After a period without use, the "Auto Power Off" function automatically
switches off the instrument. To switch on the instrument again/self-test, briefly hold the test probes together.
