Operating Instructions
Thank you for purchasing our TESTER
2550LCD
with LCD screen. The device can be used to detect DC and AC
voltages of between 6 and 1000 V, for polarity, phase sequence and throughput testing at up to 2 k
Ω
, and for
FI/RCD tests.
The TESTER
2550LCD
carries a high protection rating (IP65), making it suitable for use in harsh conditions.
1. 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 6643-3. 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, 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.
•
Spannungen >35V dienen nur zur Warnung von lebensgefährlichen Spannungen, nicht zur Messung
•
The additional
warning triangle and acoustical signal >35V is only for warning of life risk not for
measuring.
The audible indication should be considered against noise environment for audibility
2. General points
Voltages have priority. If no voltage is detected at the probe tips (< 3.0V), the device is in throughput testing mode.
3. Function
The device is activated and shut down with the “ON/OFF” switch. The “Auto Power Off” function of the device
activates after about 7 minutes.
By pressing the D-H switch longer than 2s the LED torch will be switched on.
4. 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.
5. 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.
6. 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.
7. “Data Hold” function
Press the “Data Hold” button to save the LCD screen of Resistance Measurement reading to memory. The “Data
Hold” function, which is indicated by “D-H” in the display field, can be toggled by repeated pressing of the same
button
