• Sampling value. This proceeding performs a calibration of the analog input
on two points of the scale taking as reference two known values (for example
for a load cell these values could be Zero balance and Reference weight). It
is possible to link the calibration lower limit (parameter 6 Lower lim.) to the
minimum value of the sensor or to the minimum position of the potentiometer
while the calibration upper limit (parameter 7 Upper lim.) may be linked to the
max value of the sensor or the maximum position of the potentiometer.

• Full-scale % value. This proceeding is available for 6wires (4wires+2 wires
calibration) strain-gauge sensors and for Melt transducers. It is possible to
calibrate reading of analog input by choosing the percentage of the full-scale
value at which the calibration of the upper limit will be performed. At first
the operator will be asked to select the percentage for the calibration of
the upper limit. Afterward the lower limit value and upper limit value (% of
full-scale value) will also be calibrated, as for the sampling value. The two
calibration wires of the sensor can be connected to relay of output Q2 to
perform a semi-automatic calibration. In this case it is necessary to select the
option Calibration % on parameter Alarm 2 - Type of alarm. If contact Q2 will
not be used to generate sensor calibration signal, it is possible to short-circuit
externally the two wires, waiting for stabilization of reading on the device and
then proceeding to calibration of upper limit.

Press " m " to calibrate lower limit and " n " to
calibrate the upper limit.
Use the arrow keys to set the calibration
percentage, then confirm with "Ok".
