8. Auto Stability Function (ASF)
ASF adds an extra level of versatility to the smartCHEM-Titro. When ASF is activated, the
smartCHEM-Titro monitors all parameters that are currently in use. When ALL parameters
become stable, the readings are frozen on the display.
ASF is automatically activated during a Titration procedure, so there is no need to press any keys
to start it.
ASF can be used in the following ways…
8.1 ASF During Normal Measurement
1. Press in normal measurement mode. All active parameters are highlighted and the symbol
appears in the display. For example…
7.00pH 25.0
O
C
31/12/04
Stabilising 12:00:00
As each parameter becomes stable, the highlighting is removed. If any parameter subsequently
becomes unstable, the highlighting is applied again.
The highlighting is provided to give the operator a visual indication of exactly which
parameters have not stabilised in case user intervention is required.
2. When ALL parameters have stabilised, all highlighting will be removed and the will change
to a . All readings are now frozen. For example…
7.00pH 25.0
O
C
b
bb
b 31/12/04
12:00:00
3. The operator can now make a note of the reading as required.
4. To unfreeze the display in order to take the next reading, press again to re-start the
ASF sampling process.
5. Press a second time, while the symbol is being displayed, to turn ASF off.
8.2 ASF During Calibration
The Automatic Stability Function is automatically invoked during calibration. The stability
parameters programmed into the smartCHEM-Titro have a finer tolerance during calibration than
during normal measurement. This is done to ensure the most accurate possible calibration results.
Press while the symbol is being displayed during calibration to turn ASF off and calibrate
immediately, before the reading has stabilised.
See the calibration sections of this manual for further details on the ASF function during
calibration.
