8 - Maintenance
8.1 - Instructions for Hardware
There are no parts or components in the T-650PH temperature calibrators that
can be repaired by the user. Only the 6Amp fuse, placed within the socket on the rear
can be replaced by the user (10 Amp fuse for model T-650PH 110Vac).
The fuse may blow due to a voltage spike in the mains or a calibrator component
fault. Replace the fuse once. If a second fuse blows again, it is because the fault is not
that simple. Contact Presys Technical Support Department or send the calibrator to the
factory for repair.
8.2 - Instructions for Insert Jamming
If, by chance, it happens that an insert jams inside the block proceed as follows.
1- apply a lubricant oil between the parts;
2- apply cooling liquid inside the insert wells in order to contract the insert;
3- try again to withdraw the insert.
After taking the insert out, sand both the surfaces with thin sandpaper polish them
with a suitable paste and finally clean the parts using alcohol or solvent.
9 - Instructions for Fitting the Strap for Transport
The strap for transport is included together with the dry block. It is very useful
during the transport period and its fitting is very simple. Just manually screw the screws
on each tip of the strap in the holes located on the dry block sides. See illustration below.
