usage
STATUS BYTE
0 OPC Set by the OPC command when all measurements are
complete
1 unused
2 Query Error Set on output queue overflow (Too many responses

3 unused
4 Execution err Set by an out of range parameter, or non-completion of
some command due a condition such as an incorrect

over the communications interfaces. The bits in this register stay set once set and are cleared by reading them
or by the *CLS command.

1 A/D Error Set when an A/D conversion fails.
2 Overload Set when the gain stage is overloaded.
3 Underrange Set when a measurement is below the nominal range of
