VACUUM SENSOR CALIBRATION SCREEN
Note: To exit without calibrating, press MENU at any time.
Note: A calibration at atmospheric pressure is recommended anytime conditions -
temperature as well as atmospheric pressure - have changed from the last calibration. A
deep vacuum calibration has been done at the factory and only needs to be done again if
the deep vacuum values are off.
1. Press VACUUM in the calibration screen. The manifold will warm-up the sensor.
VACUUM SENSOR ATMOSPHERIC CALIBRATION SCREEN
1. After the sensor is warmed up, make sure the manifold is at atmospheric pressure.
Press CAL ATM.
2. Press ATM to save the calibration and return to the main screen.
VACUUM SENSOR DEEP VACUUM CALIBRATION
Return to the MENU/CALIBRATION/VACUUM screen.
1. Attach an accurate vacuum gauge to the manifold.
2. Attach a vacuum pump to the manifold.
3. After the sensor has warmed up, press DEEP VAC.
4. Draw a vacuum until the accurate vacuum gauge reads under 100 microns.
5. Adjust the vacuum value on the screen using the up and down arrows to match the
accurate vacuum gauge and press SAVE.
UNITS SETTING SCREEN
1. Press SETTINGS in the MENU screen
2. Press the desired units to highlight them.
3. Press START to set the manifold to the highlighted units and return to the MENU screen.
