TESTER
2550LED

Operating Instructions
Thank you for purchasing our TESTER 2550LED . The device can be used to detect DC and AC voltages of be-
tween 6 and 1000 V, for polarity, phase sequence and throughput testing at up to 500 k
Ω
, and for FI/RCD tests.
The TESTER 2550LED 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 61243-3. In order to ensure that the unit is operated correctly and safely, read these operat-
ing 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 work-
ing 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.
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 (< 3.6V), the device is in throughput testing mode.
By pressing the “Light”switch the LED torch will be switched on
3. Self testing
Hold the probe tips together when carrying out this test. The Rx/
Ω
LED must light up brightly. Otherwise, the batter-
ies must be replaced.
Note:
If measuring 35 V AC or more, the tester performs a self test whereas all LED’s will light up. This step is necessary
to display a life-threatening voltage!
4. DC voltage testing
When the probe tips are connected to a DC voltage within the nominal voltage range, the LED corresponding to the
voltage will light up. One of the LEDs beside “12” will light up to show the polarity corresponding to “+” and “-“ on
the probe tips.
5. AC voltage testing
When the probe tips are connected to an AC voltage within the nominal voltage range, the LED corresponding to
the voltage will light up. Both of the LEDs beside “12” will light up.
From a voltage more than 35 V (
life risk
) a
buzzer sounds up.
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 “<L” LED will light up.
