Once the correct password is provided, select the output to be calibrated. Choose
the type of output (0 to 20 mA, 0 to 5 V or 0 to 10 V) and press ENTER.
The display will show the mnemonic related to the first point of calibration. There
are only two points for output calibration.
For current output, the mnemonics are related to 0 and 20mA electric signals. For
voltage output, the mnemonics are related to 0 and 5 V or 0 and 10 V signals.
Press ENTER after the display shows the mnemonic related to the first or second
point of calibration, so that the display shows a value corresponding to the output signal.
Then use the UP and DOWN keys to set the output value read by the external calibrator
equal to the electric level indicated by the mnemonic. After the output value is set, press
ENTER. During the first point calibration (0mA, 0V) be careful not to saturate the
output signal.
After calibrating the two points, the calibration process will be finished.
It is possible to calibrate only one point without rendering invalid the other one
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.
Return to factory calibration
The Indicator stores the factory calibration parameter values on the non-volatile
memory, which may be recovered at any time.
In case of a bad performance of the instrument due to an incorrect calibration,
use the REC option (see Figure 22).
REC - is the option that allows to recover the factory calibration.
Enter level 5 of Calibration and select the REC option by pressing ENTER in
order to recover the values from factory.
