To start, remove the filter from the probe and insert the probe into a
measurement hole of the driest reference chamber you intend to
use. Proceed from low to high humidity. Remember to allow at
least 30 minutes for the sensor to stabilize at each point.
7. Once you have completed the list, remove the probe from the last
measurement chamber and re-attach the filter.
8. Using the serial connection command line, issue the MPC RH
INIT command and start entering the readings and reference points
from the list you prepared in step 6. When you have no more points
to enter, press enter to save the points.

>mpc rh list
MPC : OFF
# Reading Reference Correction
1 12.20 11.00 -1.20
2 34.00 33.00 -1.00
3 75.50 75.00 -0.50
4 97.30 97.00 -0.30
10. If you are satisfied with the correction list, enable multipoint
correction by issuing the command MPC RH ON.
>mpc rh on
11. Multipoint adjustment is now complete. To exit adjustment mode
and return to the normal mode, issue the RESET command.
The multipoint adjustment can be disabled with the MPC RH OFF
command, and the correction list can be cleared with the MPC RH
CLEAR command. Note that using MPC configuration commands
requires pressing the adjustment button. The current status can be viewed
with the MPC RH LIST command also outside of the adjustment mode.
