The MDM300 Calibration look-up table is divided into three columns.
The values in the first column POINT represent the thirteen nominal calibration points,
spread at 10 °C intervals over the instruments operating range of -100...+20 °C
(-148...+68 ° F
)
. 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 MDM300 represents the reading that the MDM300 was showing at
the corresponding REF level input.
The values in both the REF and MDM300 columns can be edited by means of the

and

keys. The

and
ƒ
keys provide the means of switching between corresponding table
columns.
