We are experiencing somewhat of a chronic SX50 problem here when we try to

exchange specimens, which may be getting worse. The system pumps fine, but

the SX50 refuses to request GV3 because it won't switch over to the Penning

guage from the thermocouple gauge to read the fine vacuum (or it takes a

very long time, say 15 minutes). I would have thought this was a simple

time delay ... is the vacumm logic linked to somethin else??? Thanx in

advance ...



cheers, shaf
