CAUTION
The Touch Control must be shut down properly by deactivation with the
power switch on the rear of the instrument before the power supply is
interrupted. If this is not done, then there is a danger of data loss.
Because of the fact that the power supply for the Touch Control is pro-
vided through the pH Module, you must never disconnect the pH Mod-
ule from the power grid (e.g. by deactivating with a connector strip)
before you have deactivated the Touch Control.
If you would prefer not to position the Touch Control directly next to the
pH Module, then you can lengthen the connection with the 6.2151.010
cable. The maximum connection length permitted is 5 m.
