Manual Calibration is used to "wet calibrate the cell". This can be done with the cell installed in the
process, or with the cell suspended in a known buffer solution.
When calibrated "In Process", the actual conductivity is determined with a grab sample or a hand held
meter, and the value entered in the display.
When calibrated with buffers, the cell is placed in a known buffer solution, and the value of the buffer
entered on the display.
In both cases, make sure the cell has time to stabilize both in temperature and conductivity before
entering any data.
If the calibration did not appear
to be correct, press the
key which will return back to the
Manual Cal Cond menu.

back to the Manual Cal Cond
menu so the user can select
another function.
The controller will read the
Conductivity value, averaging a
number of results to get a stable
calibration value.
Use the and keys to
adjust the reading until it agrees with
the actual buffer conductivity
value
If the calibration is OK, use the
key to move the cursor over the Y
