measured by the reference thermometer. Move on to the next point or press <ESC/CLR> to end
calibration.
Second Calibration Point
Up to three points are calibrated for compensating probe gain. The three points may be chosen at
will
as long as they are in increasing order.
Moreover, if you do not think it necessary to per-
form calibration on all three points, it is possible to calibrate only the first and not the other two
(using the <ESC/CLR> key), or you can do the first and the second but not the third point.
Bring the calibrating oven to the temperature contemplated for compensating the gain of the sec-
ond point and immerse the probe in it (or the two probes of the double module). Wait until the
probes have reached the oven temperature and then press <ENTER>. The following screen ap-
pears:
First Point
100.0°c
100.55°c
100.30°c
The instrument proposes the temperatures read by the input channels A and B and an estimated
value of the oven temperature: in the figure above the instrument has found the temperatures
100.55°C and 100.30°C for channels A and B and has proposed, as oven temperature, 100.0°C.
Wait until the temperatures indicated for channels A and B have stabilised. Using the
Up
and
Down
arrows correct the calibration value proposed by the instrument (Target) and make it coin-
cide with the oven temperature measured by the reference thermometer. To confirm, press
<ENTER>: the indication of the value of the probe (or of the two probes) being calibrated will
coincide with the temperature indicated by the instrument (Target) and with the temperature
measured by the reference thermometer. Move on to the next point or press <ESC/CLR> to end
calibration.
Third and Fourth Calibration Points
The procedures for calibrating the third and the fourth point are identical to those for the second
point: ensure that you use increasing oven temperatures. Press <ESC/CLR> if you do not want to
calibrate these points.
