    We had a similar problem with a Mk 3.  After multiple attempts to fix various thing and some conversations with FEI, we eventually needed to have service come and fix the problem.  As I remember (this was several years ago), it required a new circuit board of some sort.  Sorry I can't be more helpful.

    politics is more difficult than physics.

Subject: [3dem] Vitrobot humidifier problem

Dear colleagues,

we are experiencing a problem getting the Vitrobot MarkIV humidifier to work.
As soon as we try to increase the humidity in the chamber the system gives a message saying "empty" (in the humidity panel).

We have tried emptying and refilling it again and removing any air bubble in the line but that has not fixed the problem.

When we detach the cylinder from the Vitrobot, the water doesn't splash..
Has anyone else had this problem and if so how did you solve it?

Do you have a technical manual? We never managed to get one from FEI.

Best regards
Artemis Kosta
