[3dem] 626 holder temperature

[Reinhard Rachel]

dear cryo-holder 626 experts, 

another question to this holder. 
We have a 626/70 Jeol version (vintage 2012) and were happy, so far. 
a closer look (yesterday, after a rest for 3 months) made us at least curious
to look into details and have a careful check (hopefully, not repair?): 
a) heating the holder is done with the smart controller set for 36 to 48 hrs,
to 80°C (whether good or not? remarks are welcome). How to check whether this
temperature is really set? a digital thermometer - inserted into the dewar and
touching the metal part, the bottom of the dewar - reads something like 41 C
(set at 70 C : about 36-38 or so) ... hmm. This means either, the temperature
meter of Gatan is "somewhere else" (likely the case; everything ok??), or the
temperature is not reached, at all. Or anything else?
b) the clipring - when inserted - is rather loose, and not as tight as I
thought it was; or, it should be. "It does not fit any more" - but is this the
only explanation? are the metal parts holding the clipring 'bent'? we will try
the other cliprings (we have 4 more, to try), but I also would appreciate any
comments from other users, regarding this point. 

thank you in advance! 
Kind regards, 
Reinhard
