G7167B 1290 Multisampler Sampler Leak Test

Hi All,

I was trying to perform the Sampler Leak Test on the G7167B 1290 Multisampler. Whenever it reaches the last portion of the leak test (Blindseat leak measurement) the pressure just could not build up and the whole Sampler leak test will fail.

The previous few tests have no issue meaning End Pump Check, Bypass Leak Measurement & Mainpass Leak Measurement pressure can build up at test pressure (800 bar) with a very low leak rate.

Thank everyone for their time
