The [Custom adjust] softkey opens a further dialog
window in which user-defined settings can be carried out
(see page 151f).
Mpt. interval
Interval between measurement recordings
1…9999 s | off
A measurement point interval must be entered for showing
curves and display of the live value of a SET titration. The
measurement data will always be entered in the measuring
point list at these intervals. At the same time the presenta-
tion of the curve and the calculation of the live value are
updated. If the measuring point interval is switched off no
measuring point list will be drawn up.
Temperature
Temperature setting or measuring mode
-170…25.0…500°C | auto | initial
The temperature can be automatically determined during a
titration with the aid of a Pt100/Pt1000 sensor or a com-
bined electrode with built-in temperature sensor and can be
used for automatic pH correction (if pH is being measured).
It is possible to record the temperature throughout a titra-
tion and to output it as a temperature curve.
numerical
manual input (e.g. for pH correction)
auto
automatic measurement during the
whole titration (for temperature curve)
initial
one-off measurement at the start of the
titration mode
The temperature can be included in formulas for calcula-
tions (see page 118ff), e.g. for volume corrections. The dif-
ferent system variables are listed on page 148 and 128.
Please note: start temperature ST and closing tempera-
ture CT are only available with auto.
Time recording
Recording the measurement time
on | off
For recording the titration curve on the time axis the time
recording function must be switched on. If the titration
curve is drawn on the volume axis time recording can be
switched off. This permits smaller determination files as
fewer measurements are made and stored.
