3)
Log/RF Tx interval
: choice of logging and RF transmission interval (the two inter-
vals coincide). If it is higher than the measuring interval, the average of the meas-
urements acquired during the interval will be stored.
4)
Measure interval
: choice of the measurements acquisition interval. It is forced to
the value
RF log/Tx interval
if a higher value is set
.
5)
Log erase
: deletes all stored measurements from the data logger memory.

: relative humidity calibration is only available in models with high-accuracy R.H. sen-
sor: HD35ED…TC and HD35ED…TV models. This sensor is not used in models with graphic
display; consequently the R.H. calibration is not displayed in the menu.
