REMOTE PROGRAMMING
4-11
STANDARD EVENT
bit name 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
waiting to be transmitted.)
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
operating mode.
5 Command err Set by a command syntax error, or unrecognized
command
6 URQ Set by any key press
7 PON Set by power on
This status byte is defined by IEEE-488.2 (1987) and is used primarily to report errors in commands received
over the communications interfaces. The bits in this register stay set once set and are cleared by reading them
or by the
*
CLS command.
LCR
bit name usage
STATUS BYTE
0 Math Error Set on a floating point error.
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
values for the present range.
4 Overrange Set when a measurement is above the nominal range of
values for the present range.
5 Out of Range Set when the unit is unable to make a valid
measurement on the current range.
6 unused
7 mem err the stored settings were invalid on power up.
The bits in this register are set when the corresponding event occurs and remain set until cleared by reading
this status byte or by the
*
CLS command.
