4 Tap Assign to save the changes and return to the Home page.
5 With the nitrogen probe at room temperature, record the sensor frequency displayed on the
Home page widget for 0% level.
6 Fully immerse the probe in liquid nitrogen and record the sensor frequency for 100% level.
7 Tap the level meter widget on the Home page to open the Level Meter Sensor Details
page.
8 Tap the Nitrogen tab.
9 Set the Pulse Counting Period (ms) to 750.
10 Connect the nitrogen level probe to the level meter board at the rear of the iTC using the
cable supplied.
11 Fit the probe to the system and fill it with liquid nitrogen. Wait for the boiling to subside.
Record the pulse count reading and use this for Frequency at 100% value.
The board should start measuring after about 10s, giving an actual pulse count
measurement of the probe. If the probe is warm (eg. out of the system), this reading should
be converted and used for Frequency at 0% value.
