DigiCal DCS 2
2.4.3 Calibration function -
Despite high quality manufacturing techniques, each probe is slightly different from
specified standards. To eliminate inaccuracies caused by exchanging or ageing of probes,
the instrument offer easy calibration functions which guarantee that the system accuracy
is always as good as if the instrument was specifically calibrated to the individual probes in
our laboratory.
The instruments offer three calibration options:

Probe and electronics are being calibrated at the same time. Therefore the
accuracy reaches 0,03°C for temperature range –100°C to +150°C.
