Instruction manual

Air Temperature Registers

AiRanger XPL, XPL Plus and DPL Plus Air Temperature registers contain a value derived from the air

temperature measurement for the associated point of measure. Subtract 100 from the decimal equivalent of

this value for degrees Celcius. Port 1 Air Temperature registers range from 40031 to 40040, corresponding to

points of measure 1 to 10 respectively. ( DPL Plus Port 1 Air temperature registers range from 40010 to

40012 ).The Air Temperature register value range is ($32) = 20 = - 80°C to ($FA) = 250 = 150°C).

Percent Registers

AiRanger XPL, XPL Plus and DPL Plus Percent registers contain the linear or volumetric reading value as a

percent of span. Two registers are used for the value associated with each point.

Port 1 Percent registers range from 40041 to 40060, corresponding to the AiRanger XPL and XPL Plus points

of measure. ( DPL Plus Port 1 percent registers range from 40013 to 40018 ). Registers 40041 and 40042

apply to point 1, 40043 and 40044 to point 2, etc.

Check the first register for a value of 56,797 ($DDDD) (point out of service) or 61,166 ($EEEE) (display

overflow).

For any other value, convert the register values to a floating point decimal (FPD) value by:

FPD = Register 1 (decimal equivalent) value +

10,000

The range of FPD values possible is 0.0 to 9,999.9999
