Hi Andrew,
Possible the memory IC could have corrupted if all the dc supply voltage to the ICs are good.

HI Tony,

For more information I suggest that you check with the seller. They should have the info of the tester spec.

Hi Jestine.

I’m looking for a ccfl tester and I see the same tester that you say above.
I have one question to solve before I order. How this tester can regulate the voltage/current at different lengths of lamps.
