Field Calibration

  1. We only recommend calibrating the DT400Y in a slush ice solution – that’s 60% crushed ice and 40% tap water – or a water bath if you have one
  2. Place the probe of the DT400Y into the slush ice solution until at least half of it’s stem/shaft is submerged
  3. Wait a moment or two for the reading to stabilize – usually a couple of degrees of the freezing point
  4. Press and hold the CAL button for 8 seconds until the word CAL is displayed
  5. Remove the probe and continue to use as normal
