CALIBRATE BAROMETRIC PRESSURE
CALB <press> [period] [average]
<press> - is a real number that represents the local barometric pressure.
[period] - optional: sets the period for the CALB routine. If this value is not entered, the
default period will be 300 microseconds.
[average] - optional: sets the average for the CALB routine. If this value is not entered, the
default average will be 64.
Commands the DSA-PTP 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 pressure from the zero pressure and enter the difference in the delta array
(LIST D)
NOTE: 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 will not
perform a CALB on that channel.
The pressure entered as the barometric pressure must be in the units defined in CVTUNIT
(i.e.: PSI, kPa, etc)
NOTE: The optional period may be the only optional parameter entered. If the optional aver-
age is entered, the optional period must be entered.

To correct all absolute sensors to read the local barometric pressure:
Disconnect all inputs.
Enter the command:
CALB <press> (Where <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 com-
mand: CALB 14.696
If CVTUNIT is set to kPa, and the local barometric pressure is 101.3254, Enter the com-
mand: CALB 101.3254

Commands the DSA-PTP to clear any errors that have occurred. The errors are sent to the
client in an ASCII Packet. ASCII Packets are described in a subsequent sections.
