vaisala

Start communication with a Vaisala RH meter.

Enter:

vaisala <device> <vap_pa> <rh> <gas_t> &

Where:

device	Specify the device name to communicate with. This is the base file name of the async configuration file.
vap_pa	Specify a CyFlex variable label where the vapor pressure will be placed. This should have units of pressure.
rh	Optional. Specify a CyFlex variable label where the relative humidity will be placed. This should have units of PCT.
gas_t	Optional. Specify a CyFlex variable label where the stream temperature will be placed. This should have units of temperature. If specified, this must be the fourth argument.

Example:

vaisala vaisala VS_vap &
Save only the vapor pressure

vailasa vaisala VS_vap rel_hum air_temp
Save the vapor pressure, relative humidity, and air temperature

Notes:

This command is normally placed in /cell/go.scp so that it runs all of the time.

A copy of the vaisala.cfg file is located in cyflex/specs.def at CTC and in cyflex/specs.def at “cmxnode1”.
