Operating Instructions
Thank you for purchasing your Testboy
®
Profi LCD two-pole voltage tester with LCD screen. The device can be used to
detect DC and AC voltages of between 12 and 690 V, for polarity, phase sequence and throughput testing at up to 2 k
Ω
,
and for FI/RCD tests.
The Testboy
®
Profi LCD carries a high protection rating (IP65), making it suitable for use in harsh conditions.
Notes on safety:
You have selected a device that is designed to offer you a high degree of safety. It conforms to standards DIN
VDE 0682-401 and IEC/EN 61243-3. In order to ensure that the unit is operated correctly and safely, read these
operating instructions thoroughly BEFORE operating the device.
The following safety precautions should be observed:
•
Check the voltage tester for correct functioning immediately before each use (as per VDE specification 0105, part
1), by connecting it to a known voltage source (e.g. a 230V 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
technician.
•
Always hold the device by its handles. Avoid touching the probe tips.
•
Note that all testing for no voltage should be carried out at two poles.
•
Trouble-free operation is guaranteed at temperatures of between -10°C and +50°C.
•
Keep the device clean and dry at all times. The casing may be cleaned by wiping with a damp cloth.
General points:
Voltages have priority. If no voltage is detected at the probe tips (< 3.0V), the device is in throughput testing mode.
1.) Function:
The device is activated and shut down at the “ON/OFF” switch. (See drawing) The “Auto Power Off” function of the
device activates after about seven minutes.
2.) Self testing:
Hold the probe tips together when carrying out this test. The buzzer on the test device should sound clearly and the display
should show "000". If the LCD screen is blank or dimly illuminated, the batteries must be replaced.
3.) DC voltage testing:
When the probe tips are connected to a DC voltage within the nominal voltage range, the reading is displayed in volts and
the “DCV” LED indicator lights up. If a negative voltage is detected at probe tip “L1”, a “-” (minus) symbol is displayed
before the reading.
4.) AC voltage testing:
When the probe tips are connected to an AC voltage within the nominal voltage range, the reading is displayed in volts and
the “ACV” LED indicator lights up.
5.) “Data Hold” function:
Press the “Data Hold” button to save the LCD screen reading to memory. The “Data Hold” function, which is indicated by
a red LED in the display field, can be toggled by repeated pressing of the same button.
6.) Phase testing:
Bring one of the probe tips into contact with a conductor, while touching the finger contact located at the back. When a
phase of min. 100V~ is connected, the small LCD screen indicates “L1”.
