Measuring parameters

Command name

25 characters, [ CAL MEAS pH # ]

Name of the command.

The measuring parameters for the calibration are defined on this tab.

Measurement with drift control

The pH calibration is carried out drift-controlled. The measurement is
stopped as soon as the

Signal drift

is reached or a

waiting time

has

elapsed.

Signal drift

0.1 ... [ 10.0 ] ... 999.0 mV/min

(Titrando)

0.5 ... [ 10 ] ... 999 mV/min

(Titrino)

The measured value is only accepted if the signal drift defined here has
been fallen short of.

Min. waiting time

0 ... [ 10 ]...999'999 s

(Titrando only)

The measured value is only accepted if the minimum waiting time has
elapsed even if the signal drift has already been reached. The drift contin-
ues to be checked as the minimum waiting time is passing.

Max. waiting time

0 ... [ 110 ] ... 999'999 s

(Titrando)

0 ... [ 110 ] ... 9'999 s

(Titrino)

If the signal drift has not yet been reached then the measured value will be
accepted when the maximum waiting time has elapsed. If no new entry for
the waiting time has been made then a suitable value for the drift will be

calculated automatically according to the following equation:

Measuring interval

0.1 ... [ 2.0 ] ... 999'999.0 s

(Titrando, increment = 0.1 s)

0.08 ... [ 2.0 ] ... 16'200 s

(Titrino, increment = 0.08 s)

Time interval for entering a measuring point in the list of measuring points.
