Calibration menu
The CALIBRATION menu is for pressure measurement span calibration. To calibrate, you need to know the pressure
measurement deviation at a single pressure.
You need the following equipment for the calibration.
- ML-SER tool.
- A reference pressure meter.
- A stable pressure source (calibration pressure must be at least 275 Pa).
- Hoses for pressure connections.
Calibration
1. Connect the transmitter and the reference pressure meter to the same pressure source.
2. Connect the ML-SER to the transmitter.
3. Navigate to the calibration menu.
4. Read the pressure values from the ML-SER tool and the reference pressure meter.
5. Press + and – buttons on the ML-SER tool to adjust the transmitter pressure measurement to same value as
the reference.
The measurement can be tuned ±25 Pa.

For example if you 5 Pa at 1000 Pa, the device will now read 1005 Pa at that pressure.
Correspondingly reading is cor10 Pa at 2000 Pa.
6. Press OK to save the span calibration.
The calibration parameter values are displayed for two seconds before returning to the menu.
