856 Conductivity Module
1.2 Instrument description
Conductivity measurements can be performed with the 856 Conductivity
Module.
The 856 Conductivity Module has the following characteristics:
￭ Operation
A touch-screen Touch Control or a high-performance PC software is
used for operation.
￭ Dosing
Dosinos or Dosimats can be used for dosing.
￭ MSB connectors
Four MSB connectors (Metrohm Serial Bus) for connecting dosing devi-
ces (Dosimat with exchange unit or Dosino with dosing unit), stirrers,
titration stands and Remote Boxes.
￭ USB connectors
Two USB connectors, with which devices such as printers, PC key-
boards, barcode readers or additional control instruments (USB Sample
Processor, Titrando, Dosing Interface, etc.) can be connected.
￭ Measuring interface
One measuring input for a conductivity measuring cell with integrated
temperature sensor.
1.3 Measuring modes and commands
The following measuring modes and commands are supported:
￭ MEAS
The following measuring modes can be selected for measurements:
– Cond (conductivity measurement)
– T (temperature measurement)
￭ CAL
Calibration.
– Cond (determination of the cell constant of a conductivity mea-
suring cell)
￭ Dosing commands
The following commands for dosing can be selected:
– PREP (rinsing the cylinder and tubings of an exchange unit or
dosing unit)
– EMPTY (emptying the cylinder and tubings of a dosing unit)
– ADD (dosing a specified volume)
– LQH (carrying out complex dosing tasks with a Dosino)
