After performing all references on the table related to the input type to be
calibrated, the calibration process will be finished.
It is possible to calibrate only one point without rendering invalid the other
points already calibrated, in case the calibration of this point was not carried out
properly.
In order to return to normal operation move back through the hierarchical
levels until reaching level zero.
Figure 23 shows the calibration options for an instrument with thermocouple
(channels 1 to 6) and RTD (channels 7 to 10) inputs.
Calibration of thermocouple input
In order to calibrate thermocouple inputs connect a voltage source to the
channel to be calibrated (see the terminals corresponding to each channel in table 2
on section 2.3.1 - Thermocouple Input or tables 6 and 7 on section 2.3.5 -
Connection for Indicators with different input types). It is required 6 voltage
references listed in table 10.
