The meaning of clearance between the sensor and the respective well should be
understood in a subjective way and common sense is very important. Thus, the
sensor should enter the insert well (both completely clean) in such a way to stay
snugly enough so that it cannot move or swing inside but it should not enter by
force to get jammed.
6 - Calibration (Adjustment)
WARNING!
Enter the following options only after understanding them completely.
Otherwise, it may be necessary to return the instrument to the factory for
recalibration!
Select the ADJUST/CAL option from the SETTINGS > SYSTEM menu. You should
then enter the password 9875 to access the calibration menu.
The password functions as a protection to calibration ranges. After the password is
entered, the menu displays the options GENERAL, INPUTS and PROBE.
Options for INPUTS are mV and thermocouple.
6.1 - Input Calibration
The following procedure applies to input for reference and auxiliary. Inputs must be
adjusted separately
Select the corresponding mnemonic and apply the signals presented in the tables
below. Note that the applied signals just need to be close to the values shown in the table.
Once the signal has been applied, store the values of the calibration points 1 and 2.
Press SAVE to save the typed values
mV Input
Single range
The cold junction calibration (Thermocouple) is performed measuring the mV(-)
terminal temperature. Store only the point 1.
