5.2 Data logging
Data logging can be started or stopped both in the HP23 standard operating mode and in the AW mode.
The HP23 can log up to10,000 relative humidity and temperature value pairs 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 directly recorded by the HP23 but it
can be added to the humidity and temperature data after downloading the recorded data to a PC with the
HW4 software. See the following HW4 manual: E-M-HW4v3-F2-012
