3.4.1Calibration Settings
1. Calibration status: When calibration has been performed, CAL-1 will be displayed in the main display area, and
when it is not calibrated, CAL-0 will be displayed. Short press Enter button to go to calibration process.
2. Cancel calibration: The main display shows FAC, short press Enter button to cancel calibration.
3. Cancel zero: The main display shows ZERO, short press Enter button to cancel zero.
3.4.2Calibration Process
There are two situations of calibration.
(1) Single-range instrument: 2-point calibration, the default calibration points are upper and lower limits of the range.
The order is to calibrate the lower limit first and then the upper limit. After the upper limit is calibrated, it will return to the
calibration status interface.
(2) Dual-range instrument: 3-point calibration, the default calibration points are the lower limit of the range, zero point
and the upper limit of the range. The order is to calibrate the lower limit first, then calibrate the zero, and finally calibrate
the upper limit. After the upper limit is calibrated, it will return to the calibration status interface.
Now taking the (0~100)kPa instrument as an example to illustrate the calibration process: short press the Enter
button under the calibration status menu to enter the calibration process:
