1.4 Jack field
Warning
Only connect sensors to the measuring instrument that cannot return
any voltages or currents that are not allowed (> SELV and > current cir-
cuit with current limiting).
Almost all sensors - in particular WTW sensors - fulfill these conditions.
Maximum number
of sensors to be con-
nected
The following sensors can be connected to the Multi 197i (maximum
configuration):
z One pH depth armature or
one pH electrode (combination electrode
or pH electrode + reference electrode). Please make sure that only
one pH sensor is connected at the same time.
z One D. O. sensor
z One conductivity measuring cell
z Option: One external temperature sensor
Note
The pH depth armature is affected by other sensors if it is connected to
them galvanically. For this reason, the pH depth armature cannot be
operated in the same test sample together with another sensor on the
instrument.
