5.2 - Probe Calibration
To readjust the internal Probe it is necessary to compare the value indicated by
the calibrator (Probe) and the temperature value from a standard probe placed in the dry
block insert. The temperature of the standard probe should have high accuracy.
The option to adjust the internal sensor has seven points of adjustment. These
points are recorded via points 1 to 7.
Before starting the calibration (adjustment), record in these points the respective
initial storing values, according to the table below:
For the TA-60NL
Calibration
Point
Point 1: -60 °C
Point 2: -2 °C
Point 3: 30 °C
Point 4: 60 °C
Point 5: 90 °C
Point 6: 120 °C
Point 7: 140 °C
Select the calibration point and then press CHANGE TEMPERATURE. Wait for
the complete stabilization of the point. On the field Adjusted Point, write the value
presented in the standard thermometer and confirm in SAVE button. Go to the next point
and continue the adjustment until the last point.
Note: It is recommended to start the adjustment from the highest temperature
point (point 7: 140 ° C) so that the humidity of the air does not interfere in the
results.
