7 - Instructions for Hardware Maintenance
There are no parts or components in the T-25N temperature calibrator that can be
repaired by the user. Only the 6Amp fuse, placed within the socket on the rear can be
replaced by the user.
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. Send the calibrator to the factory for repair.
8 - 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 in the dry block sides. See illustration below.
