3 Press the <M> key until TDS appears on the status display.
The value of the total dissolved solids appears in the upper display
line. The TDS factor appears in the lower display line.
4 Using <V> <W>, set the TDS factor (0.40 ... 1.00).
(The TDS factor has to be determined by a comparison measure-
ment before.)
