900 Touch Control

Start volume

Volume that is dosed prior to the start of the titration.

Input range

0.00000 - 9999.99 mL

Default value

0.00000 mL

Dosing rate

Rate at which the start volume is dosed.

Input range

0.01 - 166.00 mL/min

Selection

maximum

Default value

maximum

maximum
The maximum dosing rate depends on the cylinder volume (see Chap-
ter 32, page 488)
.

Pause 2

Waiting time, e.g. for the electrode to settle down after the start or a
reaction time after the dosing of a start volume.

Input range

0 - 999999 s

Default value

0 s

Initial measured value
The conditions for the entry of the first measured value in the measuring
point list are defined under [Initial meas. value].

Signal drift

Maximum permissible drift for the measured value acceptance, i.e. maxi-
mum change of the measured value per minute. For this value, a suitable
maximum waiting time is automatically calculated except you already have
modified this waiting time.

Measuring mode Ipol:
Input range

0.1 - 999.0 mV/min

Selection

off

Default value

off

off
Measured value acceptance will take place after the maximum waiting
time has elapsed.

Measuring mode Upol:
Input range

0.01 - 99.90 µA/min

Selection

off

Default value
