General; Function; Self-Test - TESTBOY Profi III LED Bedienungsanleitung

Operation
|
Correct indication is ensured in the tempera-
ture range of −10 °C
|
Always keep the appliance dry and clean. The
housing can be cleaned using a moist cloth.
|
The additional warning symbol, acoustic indi-
cations and vibration for voltages > 35 V are
only for warning of hazardous voltages, not
for measurement.
|
Before the test, check the audibility of the
warning sound at the ambient volume.
|
Immediately replace the batteries when the
battery icon is displayed.

General

Voltages have priority. If no voltage is applied at the measurement probes
(< 3 V), the appliance is in the continuous test mode. In stand-by mode, the
orange "Rx/" illuminates.

Function

To switch on the appliance, simply hold the test probes on one another.
Attaching and removing the measurement probe adapter makes it easier to
carry out measurements at the socket.
Indication of the voltage is carried out without the batteries.

Self-test

For the test, keep the probes apart. The green "Rx/" LED must clearly illu-
minate and a beep tone sounds. (After a short period, the appliance auto-
matically switches off by the "Auto Power Off" function.) If the LED does not,
or only faintly illuminates, replace the batteries.
If the appliance does not function with the new batteries, it must be protected
from misuse.
