That is very unclear, sorry.

For more information see information about the probe included in:

Regarding the HP474AC probe used, the following URL:

shows the working range of the HP474AC probe to only be 5% to 98% RH. It has a resolution of 0.1 %, but that could be very misleading because it only has an accuracy of +-2.5% in its working range. Using the probe outside its stated working range appears to be inappropriate.
