6.0 - Maintenance
6.1 - Instructions for Hardware Maintenance
There are no parts or components inside the temperature calibrator that can be
repaired by the user. Only the 10 Amp fuse for 115 V models or 6 Amp fuse for 230 V
models, placed within the socket on the rear can be replaced in case of blow.
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. In this case, contact the Presys technical support.
In case of malfunction of mA input, the input fuse (250 V/32 mA) can be
exchanged.
6.2 - Instructions for Insert Jamming
If 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 an suitable paste and finally clean the parts using alcohol or solvent.
