1.3 Titration modes – Measuring modes – Dosing com-
mands
The 902 Titrando supports the following titration modes, measuring
modes and dosing commands:
￭ SET
Endpoint titration at one or two specified endpoints.
Measuring modes:
– pH (pH measurement)
– U (potentiometric voltage measurement)
￭ STAT
Endpoint titration during which the measured value is kept constant.
Measuring modes:
– pH (pH measurement)
– U (potentiometric voltage measurement)
￭ MEAS
The following measuring modes can be selected for measurements:
– pH (pH measurement)
– U (potentiometric voltage measurement)
– T (temperature measurement)
￭ CAL
Electrode calibration.
Measuring mode:
– pH (calibration of pH electrodes)
￭ ELT
Electrode test for pH electrodes.
This mode is listed separately only in tiamo™. In Touch Control, the
electrode test is a component part of the CAL calibration mode.
￭ 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)
