Method

25 characters, [ STAT pH # ]

Name of the command.

Monitoring Measured value

on, [ off ]

If this option is switched on then the measured value will be monitored and
any limit infringements will be entered in the list of measuring points.

Lower limit pH

[ -20.000 ] ... 20.000

(Titrando)

[ -20.00 ] ... 20.00

(Titrino)

Lower limit of the measured value. When the measured value falls below
this value, the action

Measured value lower limit exceeded

is triggered.

Lower hysteresis pH

0.000 ... [ 0.020 ] ... 20.000

(only Titrando)

The lower hysteresis represents a tolerance range for the lower limit of the
measured value. When the measured value exceeds the lower limit plus this

hysteresis value, the action

Measured value lower limit ok

is triggered.

Upper limit pH

-20.000 ... [ 20.000 ]

(Titrando)

-20.00 ... [ 20.00 ]

(Titrino)

Upper limit of the measured value. When the measured value exceeds this

value, the action

Measured value upper limit exceeded

is triggered.

Upper hysteresis pH

0.000 ... [ 0.020 ] ... 20.000

(only Titrando)

The upper hysteresis represents a tolerance range for the upper limit of the
measured value. When the measured value falls below the upper limit plus
this hysteresis value, the action

Measured value upper limit ok

is triggered.

Action

Definition of the action to be taken when the limits of the measured value
are infringed:

Stop determination

The running

STAT

command is quit, then the exit track (if present) is started

and the determination is stopped.

Stop command

(only Titrando)

The running

STAT

command is quit, then the next command is started.

Wait for [Continue]

Reagent dosing in the current

STAT

command is interrupted and a message

appears. As soon as the monitored measured value is again within the lim-

its (including hysteresis) reagent dosing can be resumed by pressing the

[Continue]

button in this message window.

Wait for limit ok

Reagent dosing in the current

STAT

command is interrupted. As soon as the

monitored measured value is again within the limits (including hysteresis)
reagent dosing is resumed automatically.

[ none ]

No action will be taken.

Monitoring Dosing rate

on, [ off ]

If this option is switched on then the dosing rate will be monitored and any
limit infringements will be entered in the list of measuring points. This moni-

toring is not started until 10 s after the start of the titration.

Lower limit

[ 0.00 ] ... 166.00 mL/min

(Titrando)

[ 0.00 ] ... 150.00 mL/min

(Titrino)

Lower limit of the dosing rate. When the dosing rate falls below this value,
the action

Dosing rate lower limit exceeded

is triggered.
