Operating Instructions
Thank you for purchasing your MD 1000-LED Profi LED two-pole voltage tester with
LED 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 500 kW, and for
FI/RCD tests. The MD 1000-LED Profi LED carries a high protection rating (IP65),
making it suitable for use in harsh conditions.
Safety Notes: 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
moist cloth.
General points: Voltages have priority. If no voltage is detected at the probe tips
(< 3.0 V), the device is in throughput testing mode.
1.) Function:
The device is always activated.
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 "Rx/W". If the LED 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 "+" LED indicator lights up. If a negative voltage
is detected at probe tip "L1", a "-" (minus) symbol is displayed.
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 "+~-" LED indicator lights up.
5.) 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 100 V~ min. is connected, the
„Pol/L1" LED lights on.
