<IR Probe>
tab (see Figure 116) to access a screen in which the values of the
Adder and Multiplier can be edited. Normally, only the Adder is adjusted. From here, press
OK
and wait while the coefficients are uploaded to the LCM. When the upload is complete,
cycle the power on the LCM, and the LCM enclosure sensor reading should reflect the newly
applied calibration coefficients.
See
Section
7.5.4 for an explanation of Adders and Multipliers and their use in adjusting
internal sensors.
