5.11 Measuring with the Mütek™ PCD-05 Smart using a Wi-Fi device
Information
The pH display shown on the following screens is only
available to user who have ordered the option "pH Set"
with the instrument.
5.11.1 Setup the measurement
• Assemble the PCD-05 Smart according to chapter
4.6.3 "Startup of PCD-05 Smart", page 28.
• Turn on the Mütek™ PCD-05 Smart
• Connect your mobile device to the PCD-05 Smart
as described in chapter 5.5 "Connect a mobile
device to PCD-05 Smart", page 34.
The "Measure screen" appears:
The following values and functions are available:
5.11.2 Start measurement
• Fill a 10 ml sample into the measuring cell.
• Turn on the potential measurement.
• Wait for approximately 30 seconds until the signal
has stabilized.
- Alternative is to set a settling time under the tab
"Settings". The titration will start at the set time.
• Press "Start titration" to start a titration with the pre-
selected method
• A titration curve will be generated continuously.
• To look at the titration curve choose the tab
"Results".
• The titration stops as soon as the termination crite-
ria is reached.
Information
Since the displacement piston continuous its oscillating
movement, the steaming potential and pH signal (optio-
nal) may change. This is a normal effect without any
influence on measurement results.
• Press "Stop Titration" to stop the measurement.
5.11.3 Data handling Mütek™ PCD-05 Smart
All measurement results will be stored in the smart dis-
play memory and will be shown in a table under the tab
"Results". The Titration curves can be shown by selec-
ting the related measurements.
Potential
Indicates the current steaming potential in
mV. The value is decreasing in steps
when adding titrant.
pH
Indicates the current pH.
Demand
Shows the current titrant consumption.
When the streaming potential has rea-
ched the adjusted termination point the
titration is finished. The display shows the
consumed amount of titrant, which is
recalculated to 0 mV.
Start
Titration
Start/Stop toggle to start or stop a titra-
tion.
