7.5 Data logging function
The HF8 can log up to 10,000 pairs of relative humidity and temperature values provided by a single
HygroClip 2 probe or up to 10,000 data values provided by a single 1-channel analog probe. Both probe
inputs can be logged at the same time and in that case the recording capacity per probe is cut in half. Each
record is automatically date and time stamped. The calculated parameter cannot be recorded.
