Command Functional Groups - Honeywell HPB User Manual

HPB/HPA User Manual
•
REPEAT THE READ CONTINUOUS PRESSURE STEP ABOVE
Notice the slower output rate of one sample every 2 seconds.
•
TRY OTHER COMMANDS
Experiment with other commands to become familiar with the command structures. A short overview of
each command with input and response examples is shown in Section 3 Commands – Quick Reference.
See Section 5—Commands for complete command descriptions. Re-apply the power or send an
IN=RESET command to revert to EEPROM default settings. Until an SP=ALL command is executed, no
changes will be stored in the EEPROM.
