TESTO 240 - Error M M Essages

Conductivity mmeas. rrange hhas bbeen eexceeded
- Possible causes and • remedies:
- conductivity > 2000 mS/cm.
- conductance too high for sensor used.
• use sensor with greater cell constant.
Temp. rrange oof tthe iinstrument hhas bbeen eexcee-
ded.
- Possible causes and • remedies:
- temperature < -50 °C /-60 °F or > +150 °C/
+300 °F.
• remove probe from the substance being
measured.
Tem
perature rrange dduring nnW ccompensation,
measuring rrange oor ttemperature rrange dduring
calculation oof NNaCl h
has bbeen eexceeded ..
- Possible causes and • remedies:
with conductivity and nW compensation
- temperature is not within permissible
range 0 to +50 °C (+32 to +120 °F).
• adapt the temperature to the permissible
range
with conductivity and temperature compensation
- incorrect tc setting for given temperature,
the temperature is too low or the tc too high.
, • check temperaure coefficient, store
corresponding tc in instrument
with NaCl measurement
- conductivity too high (> 230 mS/cm)
• saturated solution (higher values not
possible).
