Connecting the curve simulator
NOTICE
Note that the dosing device is always located as the last device,
after the curve simulator, if there is a chain of MSB devices (e.g.
Titrando-MSB – stirrer – curve simulator – dosing device).
If the internal dosing drive on the Titrando is used, then the curve
simulator must be connected to MSB connector 2.
￭ Switch off the Touch Control.
￭ Connect the analog output of the curve simulator to the electrode
connector of the Titrando.
– Use the 6.2116.020 cable.
– Electrode connector Ind.: Simulation of an acid-base titra-
tion.
– Electrode connector Pol.: Simulation of a Karl Fischer titra-
tion.
￭ Connect the curve simulator to an MSB connector on the
Titrando.
