Configuring Analog Output
Set Analog Output Scaling
Use the ASEL command to show or set the scaling of the analog output.
ASEL [channel] [parameter lowlimit highlimit]
where
channel = Analog output channel, only 1 can be selected.
parameter = Parameter that is output on analog channel.
Only parameter available is CO2.
lowlimit = Lower limit of channel scaling in ppm.
highlimit = High limit of channel scaling in ppm.
Example (change channel scaling to 0 … 5%):
pass 1300
asel 1 co2 0 50000
Aout 1 quantity : CO2(0 ... 50000)
Set Analog Output Mode
Use the AMODE command to set the analog output limits and error
level.
AMODE [channel lo_value hi_value error_value]
where
channel = Analog output channel, only 1 can be selected.
lo_value = Low limit of the channel.
hi_value = High limit of the channel.
error_value = Error value of the channel.
Example (show current configuration):
pass 1300
amode 1
Aout 1 range (mA) :4.00 ... 20.00 (error :21.00)
Example (set channel to 4 … 20 mA, and error level to 3.6 mA):
pass 1300
amode 1 4 20 3.6
Aout 1 range (mA) :4.00 ... 20.00 (error : 3.60)
