Step 10. If STANDARDIZE control is out of range at all temperatures the cell
matching resistor (SOT) will have to be redetermined by the following
procedure.
(a) Set bath to 27°C and let stabilize.
(b) Set Standardize control to 500.
(c) Remove SOT (R203 on Chopper and Conductivity Board) and
substitute a 0.1 /step decade box.
(d) Determine the 2 X Conductivity Ratio required for a bottle of
Standard Seawater
(e) While running this bottle of Standard Seawater through the unit,
adjust the decade box until the proper Conductivity Ratio is
achieved. The decade box resistance is the value of the new cell
matching resistor (SOT). Install a high stability resistor of this
value and repeat step 8.
