Operating Instructions
Thank you for purchasing your MD 1100-LCD 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 kW, and for
FI/RCD tests.
The MD 1100-LCD 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
moist 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.
