i. Dew point can be displayed in either °C or °F whether it is at
the sample pressure or if it is calculated to another.
ii. When calculating the dew point at another pressure (

) the option below is enabled to allow the entry of
the pressure at which the dew point is to be calculated at.
iii. mA1 and mA3 outputs represent the setting of Channel 1
and 2 respectively.
NOTE: Changing the units clears the data logging memory and resets the
