1.3.2.2 Accessories
To operate the magnetically operated touch panel a special tool (actuator) is required. The following
picture shows this tool as it should be provided together with your analyzer. If it is missing please
contact your local sales office.
1.3.2.3 Operating the Touch Panel
The touch panel is operated by activating the reed relays using the actuator.
This is done by holding that actuator’s end in front of the key that is equipped with 2 small magnets.
As the reed relays are installed alternating vertical and horizontal to prevent accidentally activation
of an adjacent key, the actuator has to be aligned the same way.
The design foil shows for each key how the actuator has to be aligned using the symbols
