The RH values and sample RH are high
If the RH values on the display are 95% or above, water
may have entered the cuvette (see External Cleaning on
page8-1). If the sample RH (RH Sample) value on the
display is 95% or above, clamp onto a stable object, such
as a piece of printer paper, and flush the instrument’s
system until the sample RH value drops to match the
reference RH (RH Ref).
