4.1 Control settings
1. Pressure type
The ADT761A-500 and ADT761A-1K support switching between gauge pressure and absolute pressure.
2.
Slew rate limit
If disabled, the calibrator will approach the target value at the maximum control speed.
If enabled, you need to set an upper slew limit. During pressure control of the calibrator, the maximum control
speed shall not exceed this limit.
3. Stability
Input the pressure stability: One of pressure stability conditions. Compare the difference between the output
pressure and set pressure with this value. Its range is ±(0.003~1)%FS.
4. Stabilization time
Input the pressure stabilization time: One of pressure stability conditions. Pressure control is considered stable
when the difference between the output pressure and set pressure meets requirements and lasts for this duration. Its range
is 1~60sec.
The pressure can be judged stable when the following two conditions are met during control:
