About the version number:
This manual is valid for all instruments with firmware version 4.x, where 4.x can be 4.0, 4.1, etc.
(see Function Menu, SYS STATUS). Changes to the last digit of the version number reflect minor
firmware changes that do not affect the manner in which the instrument should be operated.
Note: Both instrument configuration and adjustment of the HygroClip probes require a PC with the
optional ROTRONIC HW4 software version 1.2.2 or higher. Instructions for using the software are
not included in this manual. These instructions are shipped separately on the software CD ROM.
