Can I run the Data Formatter and the hp83_to_stdf formatter at the same time?

Yes. By default the SmarTest Data Formatter will be automatically invoked when SmarTest starts. If your test program contains a call to invoke the hp83_to_stdf formatter, by default the hp83_to_stdf formatter calls will be ignored unless you have set the environment variable RUN_HP83_TO_STDF_FORMATTER to true. It is important to note that running both the Data Formatter and hp83_to_stdf_formatter could impact test time.
