EXAMPLE:
1. Calibrate to a 2000ppm CO
2
reference gas
Example:
Sent from Host: C,1,0,2000<CR>
Received from EGM-5:
+<CR>
C,1,0,2000,1.091,0
In the example, the CO
2
reading is 2000 and the calibration factor is 1.091.
F,x
Character
with
Parameters
“F” Command (Zero Valve on/off)
This command sets the Zero Valve.
x=’0’ Off
x=’1’ On
Example:
Sent from Host: F,1<CR>
Received from EGM-5:
+<CR>
F,1
In this example, Zero Valve would be set to on.
