Type of start volume (OFF, abs., rel.)

"OFF": start volume switched off

"abs.": absolute start volume in mL

"rel.":

relative start volume to sample size.

If "abs." is set:

Absolute start volume (0...999.99 mL)

If "rel." is set:

Factor for relative start volume (0...±999999).

Calculated as: start V in mL = factor

sample size

Dosing rate for start volume (0.01...150 mL/min, max.)

sets "max.".

The maximum rate depends on the Exchange Unit:

15 mL/min

60 mL/min

50 mL

150 mL/min

Pause 2 (0...999999 s)

Waiting time after start volume, e.g. reaction time after

dosing of a start volume. The waiting time can be

aborted with .

Extraction time (0...999999 s)

During this time the titration is running. It will not be

stopped (also if EP is already reached), before the

extraction time is terminated. The extraction time can

be aborted with .

Polarization current (–127...127

µA)

or the

polarization potential (–1270...1270 mV, in steps of

10 mV) is inquired.

Electrode test (OFF, ON)

Test for polarized electrodes. Performed on

changeover from the inactive standby state to a

measurement. "OFF" means that the test is not

performed.

Titration temperature (–170.0...500.0 °C).

The temperature can be entered manually.

Time interval (1...999999 s)

Time interval for acquisition of a measured value into

the measuring point list.
