Ensure the welds are clean and perfect. Once the welding operation is complete, close the two
shells, insert the gasket in the module, and screw the fairlead and the ring. At the other end of the
module, enter the ring with the O-Ring as indicated in the picture.
Make sure the cable is not twisted while you are screwing the fairlead. Now the probe is ready.
Direct connection of 4 wire Pt100 sensors
4 wire Pt100 sensors can be soldered directly
to the pins of the free female connector with-
out making use of the TP47 board. The 4

In order to use this type of probe it is neces-
sary to set up the menu item “Probe Type” as
described at page 10.
The P100 probe is recognized upon turning on
