reset the maintenance wrench on crystat CM1950 / ip adress to service the cryostat / ERROR E039

I would love the info on resetting this as well.

You can try this procedure ; "Push both the "key" symbol button and the + (specimen temp increase) for at least 5 seconds. That should clear it. If not, I also have a more involved method from the manual." "You have to press the defrost Button the arrow down Button and the key Button. Then there is a Service menu. With the arrow button you can switch to this menu. When on Display appear runtime press defrosts Button and After That press refresh button. The cryostat restarts." Reply back if this works. Thanks Paul
