Trouble-shooting

If the vessel is filled with a different material with a completely
different dielectric constant or electrical conductivity after it has
been calibrated, the calibration must be repeated.
If the electronic insert is replaced we recommend that the
Nivotester be recalibrated in order to provide the best possible
accuracy.
If the liquid or solid in the vessel tends to produce conductive
build-up at the probe:
If necessary, check and free the probes of build-up.
