pH Oxy
Information
Sensor Network Diagram (pH and Oxy only)
Provide single-glance information on the following parameters of the con-
nected sensor:
• Slope
• Zero point (operating point for Memosens ISFET)
• Sensocheck (pH) or leakage current (ISFET and Oxy)
• Response time
• Calibration timer
• Wear (Memosens)
Parameters which cannot be checked are shown as inactive (gray) and are set
to 100% (e.g. Sensocheck for analog sensors).
The parameter values should lie between the outer (100%) and inner (50%)
hexagon. When a value enters the inner hexagon (<50%), the corresponding
caption text fl ashes red (see example).
