Operation
Check the function of the voltage testing device immediately prior to
its use (VDE regulation 0105, Part 1), by connecting it to a known
voltage source (e.g. a 230 V power socket). If the indicator shows
that one or more functions are not working correctly, do not use the
device any further, but have it examined by a qualified service techni-
cian. You can contact our works service department.
Always hold the device by its handles.
Avoid touching the probe tips.
The voltage indications on the Testboy are only rated values.
Trouble-free operation can only be guaranteed at temperatures of be-
tween −15 °C and +45 °C.
Keep the device clean and dry at all times. The casing may be
cleaned by wiping with a damp cloth.
Testing DC voltage
When placing the test probes on an DC voltage within the rated voltage range, one of the lower
(6 V + -) LEDs and the LED arranged underneath them illuminate according to the voltage ap-
plied.
The upper LED indicators show the voltage, whereby the reference pole is connected to the large
hand element.
Testing AC voltages
When placing the test probes on an AC voltage within the rated voltage range, both of the upper
(6 V +~-) LEDs and the LED located underneath them illuminate according to the voltage applied.
Simultaneous lighting up of the upper LEDs indicates the presence of an AC voltage.
Phase search:
Hold a test probe against the protective conductor and check the other conductor with the other
test probe. The Testboy 40 Plus indicates the AC voltage for the phase in question. FI/RCD is not
triggered.
