8 Connection for external dosing contact
E.g. 6.2107.000 push button cable.
9 Power
connection
In power supply systems, in which strong HF
interferences (transients) are superimposed on the
power voltage, the 775 Dosimat should be
connected via an additional power line filter, e.g.
METROHM 615 model.
The main cables supplied with the instrument are
three-core and equipped with a plug with an earthing
pin. If a different plug has to be fitted, the
yellow/green lead must be connected to the
protective earth. Each break in the earthing inside or
outside the instrument can make it a hazard.
When the instrument is opened or if parts of it are
removed, certain components may be live if the
instrument is connected to the power line. The power
cable must therefore always be unplugged when
certain adjustments are made or parts replaced.
10 Earthing socket
The 775 Dosimat must be grounded correctly and
effectively, if necessary through the separate
earthing socket.
11 Connection for stirrer
In general a Magnetic Stirrer (forms a complete
titrating stand). Other stirrers may be connected as
well, e.g. a METROHM Rod Stirrer. Supply voltage
output: +9 V DC (I ≤ 200 mA).
12 Power switch
