WMA-5 Operation Manual V. 1.01 51 support@ppsystems.com
0 = Success
10 = Bad Format
11 = Device parameter incorrect
12 = Action parameter incorrect
13 = Calibration value (CO
2
) out of range
14 = Calibration factor (CO
2
) out of range
15 = Calibration failed
16 = Calibration value (O
2
) out of range
17 = Calibration factor (O
2
) out of range
Example:
1. Calibrate to CO
2
to 2000ppm
Example:
Sent from Host: C,1,0,2000<CR>
Received from WMA-5:
+<CR>
C,1,0,2000,1.091,0<CR>
In the example, the CO
2
reading is 2000 and the calibration factor is 1.091.
E,xxx
Auto
This command transmits any errors. See Error Messages for the WMA-5 Table below
for more details.
Example,
Received from WMA-5:
+<CR>
E,11<CR>
In this example, 11 is the Low Alarm error.
Fx
Standard
This command sets the Zero Valve.
x=’0’ Off
x=’1’ On
Example:
Sent from Host: F1<CR>
Received from WMA-5:
+<CR>
F1
In this example, Zero Valve would be set to on.
G,x
Standard
This command gets a parameter stored in EEPROM (non-volatile memory). The value
x is the number associated with a particular parameter (See Get/Set Parameter Values
Table below). When Gx is sent from the Host, the value associated with that particular
parameter is returned.
Example:
Sent from Host: G,1<CR> (Get Zero Type)
Received from WMA-5:
+<CR>
G,1,1.000<CR>
In this example, the value of Zero Type is 1 (Automatic).
Mx
Standard
This command performs a “one shot” output. Each time the ‘Mx’ is called one set of
data is displayed in the format that was selected previously (i.e., M1, M2, etc.). The
value of x determines where the data will be sent:
