General; Function; Self-Test; Checking The Dc Voltage - Testboy Profi III LED+ Manual De Instrucciones

Operation
The following safety precautions are applicable:
| Immediately before using, carry out a function check of the volt-
age tester (VDE regulation 0105, Part 1). Make sure that the
connecting lines and device are fully serviceable. Check the de-
vice on a known source of voltage, e.g. 230 V socket.
| Hereby, if the display fails to indicate one or more functions,
do not use the device and it must be checked by a specialist.
Only hold the device by the handles, avoid touching the probes!
|
| Only carry out checks for isolation from the power supply on both
poles!
| The device must not be operated in a moist environment!
Do not use with the battery compartment open! Whilst replacing
|
the battery, the measuring probes must be removed from the
measurement circuit.
Correct indication is ensured in the temperature range of
|
-10 °C – +55 °C.
Always keep the device dry and clean. The housing can be
|
cleaned using a moist cloth.
The additional warning symbol, acoustic indications 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 a continuous warning
|
signal sounds when switching on.

General

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

Function

To switch on the device, simply hold the test probes on one another.
Attaching and removing the measuring 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 illuminate and a beep tone sounds. (After
a short period, the device automatically switches off by the "Auto Power Off" function.) If the LED does not illumi-
nate, or only faintly illuminates, replace the batteries.
If the device does not function with the new batteries, it must be protected from misuse.

Checking the DC voltage

When placing the probes on an AC voltage within the rated voltage range, one of the lower (12 V +~-) LED's and
the LED arranged above it illuminate according to the voltage applied. The lower LED's indicate the polarity at the
test probes in accordance with the identification! (+,−)
If the threshold value of 35 V is exceeded, a signal sounds and lucid vibration can be felt. This indicates a general
hazardous voltage!
