Calibrating an In-Line Sensor
Prerequisite
• The In-Line sensor is paired with the InTap and is within the Bluetooth range of the InTap.
1. Enter "Calibrate In-Line Sensor" menu. Menu path: CAL > Calibrate In-Line Sensor
⇒ The screen "MP Select" is shown.
2. Select the MP (In-Line sensor) you want to calibrate. Therefore activate the correspond-
ing radio button.
3. Return to the next-higher menu level.
⇒ The screen "Calibrate In-Line Sensor" is shown.
4. Set the options "Cal Pressure", "Rel. Humidity" and "Stability".
5. Tap "Cal".
6. Confirm the message "There is a "auto logging" procedure running" with "Yes".
7. Answer the question "First calibration after OptoCap™ change".
⇒ The current values for the InTap sensor and the In-Line sensor are shown.
8. Tap "Next".
⇒ The values for P100 and P0 are shown.
9. Tap "Adjust" or "Calibrate".
10. Tap "Done" to finish calibration of the In-Line sensor.
Calibrating the InTap Sensor
h
Note: Use as air gas dry, clean and oil-free compressed air. Use as zero gas N
purity of at least 99.9 %. For best results use a zero gas with a purity of 99.995 %.
1. Connect the compressed air to the connection "Medium In".
2. Purge the InTap for 5 minutes with compressed air to remove the excess humidity out of
the measurement cell. Ensure a steady medium flow without pressure build-up in the
measurement cell. For this, perform two turns with the rotary knob. See Chapter 3 on
Page 48.
3. Turn off compressed air.
4. Enter "Calibrate InTap Sensor" menu. Menu path: CAL > Calibrate InTap Sensor
5. Set the units.
