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:
1) (output pressure-set pressure)<=High-pressure/low-pressure range X pressure stability
2) Meet the condition 1) continuously and reach the pressure stabilization time.
5. Automatic zeroing
Can be enabled or disabled.
If enabled, the calibrator will automatically perform pressure zeroing when vented to the
atmosphere.
6. Vent pressure
Allowable setting range of the vent pressure: Depend on the device model.
Press the “Vent” key to vent. If the pressure is lower than this value, the calibrator will open the
vent valve for direct connection to the atmosphere. If the pressure is higher than this value, the
calibrator will control the pressure below this value and then open the vent valve for direct
connection to the atmosphere.
7. Head correction
The correction type can be selected from: calculated value or fixed.
The unit can be selected from: metric (SI) or imperial (BS)
The density can be selected from: air, nitrogen or user-defined value;
The height can be input within the range of (-1000~1000) cm.
The acceleration can be input within the range of (9~10) m/s
