Conductivity measurement

Conductivity error messages

Error messages are displayed after a 5 second
display.
Error 1
Cause: The measuring range (0 µS/cm to 2000
mS/cm ) of the instrument has been
exceeded. This can indicate an
incorrect cell constant or temperature
coefficient.
Error 2
Cause: The temperature measuring range of
the corresponding probe has been
exceeded.
Error 3
Cause: The max. limit temperatures for the
calibration were either exceeded or were
not reached.
Error 4
Cause: The stored cell constant must be within
the range 0.01 and 20.00/cm. It is
possible that an incorrect value was
stored during calibration for the
calbration solution used.
Error 6
Cause: The conductance exceeds the
measuring range, although the specific
conductivity of the measuring solution is
still within the measuring range. Check
that the stored temperature coefficient
and cell constant are correct. Should no
errors be found here, the product of the
actual conductance, temperature and
temperature coefficient is really outside
the measuring range. Reduce the
temperature of the measuring solution
as much as possible or alter the
temperature coefficient to 0.0%/°C and
convert the conductance yourself.
