￭ MEAS
The following measuring modes can be selected for measurements:
– pH (pH measurement)
– U (potentiometric voltage measurement)
– Ipol (voltametric measurement with selectable polarization cur-
rent)
– Upol (amperometric measurement with selectable polarization
voltage)
– Conc (concentration measurement with or without standard
addition)
– T (temperature measurement)
￭ STDADD
The measuring modes for standard addition are listed separately only in
tiamo™. In Touch Control they are integrated in the measuring mode
MEAS Conc.
The following measuring modes can be selected for measurements:
– auto (automatic addition of the standard addition solution by
specifying a potential difference)
– dos (automatic addition of the standard addition solution by
specifying the single volume increments)
– man (manual addition of the standard addition solution)
￭ CAL
Electrode calibration.
Measuring mode:
– pH (calibration of pH electrodes)
– Conc (calibration of ion-selective 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)
