Subject: [ISOGEOCHEM] MAT253 bellows hardware calibration

Dear Isogeochemists,

apart of having the annoying problem with the slipping rubber belt (that we are dealing with for the past years); since before christmas the “Hardware calibration” does not work anymore. When doing hardware calibration (iIrrespective of doing it in the Acquisition or Instrument control window); bellows are not moving and software freezes. We are using Isodat 3.

The signal calibration still works well after adjusting the bellows potentiometer position manually.

Did any of you had a similar problem (and a solution)?
