6. Record the average TOC values from the reference analyzer and enter this value in the TOC
match screen.
7. Press F1 to accept the new TOC offset.
It may be necessary to repeat the TOC match periodically, particularly if the level of TOC or the types
of organic compounds in the water system change or if Sensor is moved to a different water system.
Automatic Offset
During on-line measurements, the Sensor monitors the conductivity/resistivity measurement from
cell 1. If the conductivity drops below 0.0546 µS/cm (resistivity goes above 18.3 megaohm cm), the
offsets for both cells are adjusted to correct the conductivity readings
