Description of probes
Conductivity calibration with a standard solution
Jump to Conductivity Soln with the arrow/print
key and confirm with Enter.
A setting appears which is valid for the conductivity
standard solution we offer (at 25 °C). If this
temperature setting of 25 °C is fulfilled, you can
confirm with Enter and the cell constant is
recalculated and automatically stored.
If the temperature deviates from 25°C refer to the
Table on page 69 . Enter the conductivity value of
the standard solution in accordance with its
temperature.
If you are using any calibration solution or the
solution be based on any other temperature, you
can set the value to that of your solution by using
the arrow key. Enter the conductivity which the
calibration solution has at the temperature just
measured. Set the unit of measurement (µS, mS or
S) according to the unit indicated on your
measuring solution and confirm the unit with Enter.
