The MDM300 I.S. Calibration look-up table is divided into three columns.
The values in the first column

spread at 10°C intervals over the instruments operating range of -100 to +20°C (-148

. These points cannot be edited.
The second column
REF
represents the value of the reference dew-point standard
applied at that particular point.
The third column
