Note
: functions such as instrument configuration with a PC as well as the calibration of HygroClip
probes separately from the HygroPalm AW1 require the optional HW3 PC software. Instructions
for using the HW3 software are not included in this manual. These instructions are shipped
separately on the same CD ROM as the HW3 software.
About the version number
: this manual is valid for all instruments with version number 3.x,
where 3.x can be 3.0, 3.1, etc. (see MENU, SYS STATUS). Changes in the last digit of the
version number reflect minor changes in the internal software of the instrument that do not affect
the manner in which the instrument should be operated.
