• Streaming potential: The streaming potential is the difference
between the voltages measured in stirred and unstirred solution.
• Drift: For each buffer, the drift in stirred solution is determined.
The sum of these values is compared with this value here.
• Slope min.: Minimum slope of the pH electrode.
• Slope max.: Maximum slope of the pH electrode.
• Response time: The voltage measured in stirred solution after three
minutes serves as a reference value for the determination of the
response time. The response time is defined as the time after which
the measured voltage is within ±1 mV of this reference value.
