(5) Compare TI %RH indication to monitor h-t indication. TI and monitor h-t will
agree within 10% RH. If not, perform b below.
b. Adjustments
(1) Calculate and record the difference between TI %RH indication and monitor h-t
using the formula below:
Monitor h-t [%RH] %RH [%RH] = Ć%RH
(2) Record the current value of the HA (Humidity Adder) from the TI display
(3) Calculate the New HA by algebraically adding the Ć%RH to the Current HA:
Current HA [%RH] + Ć%RH [%RH] = New HA [%RH]
(4) Adjust HA by pressing TI keys as listed in (a) through (f) below. (R)
