Volume increment
The volume that is dosed at each dosing step. High accuracy requires
using the correct volume increment.
A good guideline for the volume increment is 0.1 mL. A total of 20 dosing
steps is recommended until the equivalence point is reached.
With greater consumption, the titration time can be optimized using the
start conditions. Smaller volume increments (smaller than 0.1 mL) are
required to determine blank values or to ensure accuracy with highly
asymmetric curves. Larger volume increments are advisable for flatter
curves.
NOTICE
The accuracy of the evaluation cannot be increased by using smaller
increments as the measured value changes between two measuring
points are then of the same order of magnitude as the noise.
Input range
0.00005 to 999.900 mL
Default value 0.10000 mL
Dosing rate
Rate at which the volume increments are dosed.
Input range 0.01 to 166.00 mL/min
Selection maximum
Default value maximum
maximum
The maximum dosing rate depends on the cylinder volume (see chap-
ter 32, page 492).
Signal drift
Maximum permissible drift for the measured value acceptance, i.e. maxi-
mum change of the measured value per minute. This type of titration is
often referred to as equilibrium titration. For this value, a suitable maxi-
mum waiting time is automatically calculated except you already have
modified this waiting time.
