Note: The number of decimal places to be displayed is determined by the Gas Range Max setting as follows:
This is also the resolution at which data will be logged for the trend report.

Maximum 10 Alphanumeric Characters
%FSD, % Vol., ppm, ppb, mA, mV, mg/
m3, LEL.m or maximum 5 Alphanumeric
Characters
180 to 360 mA
0 mV to 100 mV

Comment
FSD – Full Scale Deflection
LEL – Lower Explosive Limit
LEL.m – LEL metres
Comment
X1 = Signal Range Min (Electrical Input from Sensor)
X2 = Signal Range Max (Electrical input from Sensor)
Y1 = Gas Range Min
Y2 = Gas Range Max
Gas concentration (y) is calculated as follows:
y = (((Y2-Y1)/(X2-X1))*(x-X1))+Y1
Note: Signal Range Min and Max are over-written
during calibration, and are then no longer editable
Comment
If Peak Hold is enabled and the gas reading rises
above the configured full scale value, the channel
will display the maximum gas reading that has
been measured until it is reset
