Operation 16
Measuring the salinity (SAL)
The main display indicates the measured salinity in ‰
(parts per thousand), the secondary display shows the
temperature.
TDS determination (TDS)
The main display indicates the concentration of the dis-
solved solids contributing to the solution conductivity (TDS,
comparable to the evaporation residue) in mg/l, the sec-
ondary display shows the temperature.
Pressing the
meas
key and then the
Y
or
B
key sets the
TDS factor within the range 0.40 – 1.00.
The TDS factor depends on the composition of the water
to be tested and must be determined for each water type.
The man indicator signals that no temperature probe is
connected. The meter operates with the manually specified
temperature. The manual temperature can be edited with
the
Y
and
B
keys in the Cond measuring mode.
