Note: y is the minimum, z is the maximum, set range-32767-32767,
corresponding to-3276.7-3276.7;
Set to 10 times the actual value.
Example: setting minimum value -12.3, maximum value 45.6,

9.17. Calibrate the accuracy of AIN (only for AIN input)
Instructions
Return
Set
PVOL=x
Note: x is the calibration value, generally 3200~3400;
The factory accuracy is calibrated and please do not set it if no
necessary. If recalibration is required, please first inquiry the calibration
value and set it on the original basis: Increase the calibration value to
increase the AIN measurement value, decrease the calibration value to
decrease the AIN measurement value;
For example, if the factory calibration value is 3315: if the AIN
measurement value is smaller than the actual value, you can try to
increase the calibration value like 3325, 3335, 3345… if the AIN
measurement value is larger than the actual value, you can try to
decrease the calibration value like 3305, 3295, 3285…
Example: set the calibration value to 3300, instruction 1234VOL=3300
VOL: x
