Shaw SDHmini - Selecting Gas Molecular Weights; Pressure

18
6.3 Selecng Gas Molecular Weights
The SDHmini default seng is for air (molecular weight 28.99), however, this
funcon allows the molecular weight to be set appropriately for other sample
gases, for example 18.99 .
6.4 Pressure
This sub-menu has, for both the primary and secondary displays, ve opons
allowing the user to select either atmospheric pressure or one of four pressure
engineering units and applied pressure.
When this funcon is selected, the main and secondary display screens will display
the pressure at which the dewpoint reading is calculated.
The SDHmini requires that a numerical pressure value be entered in the selected
units at the boom of the units selecon secon, for example selecng pressure
dewpoint of 2,000 psig on secondary display.
Warning: This funcon is purely an internal calculaon and DOES NOT allow an
elevated pressure to be applied to the measuring head.
