COMMAND CALIBRATE BAROMETRIC PRESSURE

COMMAND SYNTAX CALB <press>

ARGUMENTS <press> - is a real number that represents the local barometric pressure.

DESCRIPTION Commands the DSA to perform the following:

1) Read the current counts and enter them in the zero array (list z)

2) Lookup the counts for the pressure entered at the current temperature

3) Subtract the table counts from the zero counts and enter the difference

in the delta array (list d)

In order for the correction to be active, ZC must be set to 1.

The CalB function only uses the entered pressure for channels that are

defined as absolute sensors (ABS(x) = 1).

If a channel is not defined as an absolute channel, the software it will

perform a CALZ on that channel.

The pressure entered as the barometric pressure must be in the units

defined in CVTUNIT (i.e.: PSI, kPa, etc)

RETURNS <nl> - end of line

EXAMPLE To correct all absolute sensors to read the local barometric pressure:

Disconnect all inputs.

Enter the command:

CALB <press> W here: press is the local barometric pressure in

the current engineering units.

If CVTUNIT is set to psi, and the local barometric pressure is 14.696

psia,, Enter the command:

CALB 14.696

If CVTUNIT is set to kPa, and the local barometric pressure is

101.3254, Enter the command:

CALB 101.3254
