locking screws each time you transport the instrument a significant dis-
tance.

3.5 Connecting the drainage tubing and leak sensor
The leak sensor detects leaking liquid that collects in the instrument's base
tray. Liquid that leaks in the bottle holder or in the detector chamber is
routed to the base tray using drainage tubing and is detected there.
If the leak sensor detects a leak in the IC system, the IC instrument is
switched off and a warning is output in the software.
The leak sensor functions properly only if the following preconditions are
met:
￭ The drainage tubing is connected.
￭ The leak sensor connection cable is inserted into the leak sensor con-
nection socket.
￭ The 940 Professional IC Vario is switched on.
￭ The leak sensor is switched to active in the software.
3.5.1 Installing the drainage tubing
Liquid that leaks in the bottle holder or detector chamber flows to the rear
of the instrument and is drained through openings on the bottle holder
and in the detector chamber. The drainage tubing has to be mounted at
these openings. This drainage tubing guides the leaking liquid to the base
tray where the leak sensor is located.
