7.2 - Probe Calibration
The options of CAL>PROBE are:

ºC RESTORE
ºC : Adjust of the internal temperature sensor (internal Probe).
RESTORE : Restores the internal temperature sensor calibration parameters to
the factory values.
To readjust the internal Probe it is necessary to compare the value indicated by
the calibrator (Probe) and the temperature value from an external probe placed in an
insert. The temperature of the external probe should have high accuracy and should be
measured by a superthermometer (ST).
The option to adjust the internal sensor has seven points of adjustment. These
points are recorded via keys 1 to 7.
Before starting the calibration (adjustment), record in these points the respective
initial storing values, according to the table below.
Go to the manual operating mode (menu EXEC ) and generate all the seven
levels of temperature (set points from the table), writing down the value indicated by the
superthermometer (ST). Now, go back to the option Calibration/ Probe / ºC and record
the values indicated by the superthermometer.

There are no parts or components in the T-1200PIR temperature calibrators that
can be repaired by the user. Only the 10 A 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. Contact the Presys technical assistance or send the calibrator to the factory
for repair.
