Command:
1VSET:6,1<CR> - Set CONC_UNITS VAR to ppm
Response:
1:OK#261<CR> - VSET Successful
1:FAIL#391<CR> - VSET Failed
NOTES
ANALOG_RANGE: Setting is in whatever units selected by the CONC_UNITS VAR
ALARM_ENABLE: The concentration alarms cannot be enable/disabled independently.
ALARM_MODE: The mode of the concentration alarms cannot be set independently.
CARRIER_WEIGHT: This variable is only used by 460L’s with ppm by weight capability (ppmw).
The molecular weight of pure O
2
is 32.
The nominal molecular weight of ambient air is 28.96
COM_MODE: The 460L does not use the comm_mode VAR, so its value will always be 0.
IIR_FILT: The lower the setting value the more significant the effect of the filter; 1.0 = No
filtering; 0.05 = Maximum filtering. 0.0 is not allowed.
HIHI_AL_LEVEL must be greater than HI_AL_LEVEL. New_value should be in the units of
measure the monitor for which the monitor is set.
EXAMPLE:
1VSET:8,275.0<CR> - Set HI-HI concentration alarm to 275.0 ppb
1VSET:8,0.275<CR> - Set HI-HI concentration alarm to 0.275 ppm
