CCFL (Cold Cathode Fluorescent Lamp) – Lamp Tester 10W - CHS Pt. No. 9091257
To enable functional testing of LCD Panel Cold Cathode Fluorescent (CCFL) and External
Electrode Fluorescent Lamps. The lamps can be tested in the inserted condition (in situ). The
connection of the lamps is made by means of clamp connectors or by an adapter plug.
It can be used for all lengths, diameter and forms of CCFL and EEFL lamps.
When making functional lamp tests, Note:
a)... ensure the lamps under test are SWITCHED OFF when connecting or separating the lamp
tester, otherwise the lamp tester can be damaged!
b)... the lamp tester generates a high voltage of up to 2000V AC!
c)... the lamp tester should be operated by experienced service personnel.

For the operation of the CCFL Lamp Tester a power pack of DC 12v, min. 1.0A is required. It is
not supplied Order Code. S660445 is recommended.
Also Connection Kit available. Order Code….. 9091249 (connectors also sold separately)
Execute a Function Test
1. Connect the 12v power supply plug
Note: the 12v positive terminal to the centre pin.
2. Connect the CCFL/EEFL Lamp
a. With the Adapter plugs
Red cable is High tension
White cable is Low tension
b. With the Clamp Connector
Red Clamp is High tension
Black clamp is Low tension
3. Switch the On/Off switch of the Tester to On (I)
4. Check whether the GREEN LED is lit
a. LED LIT, lamp tester is ready to use
b. LED NOT lit, lamp tester is not ready to use
5. Check whether the RED LED is lit
a. RED LED NOT lit, connection to lamps is OK
b. RED LED LIT, there is bad lamp connectivity
6. Switch off the tester after the above tests.
Further measurement of the lamps can be made as follows:
a. Measurement of Lamp Current.
The lamp current can be measured using a digital current analyser.
Lamp Current is approx 6mA.
Measuring instrument is an Agilent 34401A
b. Measurement of Lamp High Voltage.
The HV can be measured using a High Voltage Probe
CCFL length is 650mm
