3 Operation
The most important points concerning the operation of the Touch
Control and PC Control are described in this section. As the
appearance of the operator interface and the functions are almost
identical, only the PC Control operator interface is shown. If individual
functions are only available in Touch Control or in the PC Control
software then this is indicated accordingly in the text.
The arrangement of the program and the operating concept are
identical for Touch Control and the PC Control software. In Touch
Control operation is carried out via a touch-sensitive screen (Touch
Screen), in PC Control the software is operated by using a mouse and
the PC keyboard. This results in several system-specific operating
possibilities.
3.1 Operating principles: Touch Control
3.1.1 Switching Touch Control on and off
A Touch Control which is properly connected to a Titrando is switched
on and off with ON/OFF switch 11 on the rear panel of the instrument.
Attention!
The Touch Control must be shut down properly by switching it off
with the ON/OFF switch on the rear panel of the instrument before the
current supply is interrupted. Otherwise there is the risk that data may
be lost. As power is provided to the Touch Control via the Titrando,
the Titrando must never be separated from the mains supply (e. g. by
switching it off via a multiple outlet strip) before the Touch Control has
been switched off. When the Touch Control is switched on all the
other peripheral devices (e. g. printer) must already be switched on.
We recommend the following procedure:
Connect all the instruments (Titrando and peripheral devices) to the
mains supply via a multiple outlet strip with mains switch.
When switching on first switch on the multiple outlet strip with the
Touch Control switched off. Then switch on the Touch Control.
When switching off proceed in the reverse order. First switch off
the Touch Control. Then switch off all the peripheral devices via the
multiple outlet strip switch.
