REMOTE PROGRAMMINGSTANDARD EVENT bit name usageSTATUS BYTE0 OPC Set by the OPC command when all measurements arecomplete1 unused2 Query Error Set on output queue overflow (Too many responseswaiting to be transmitted.)3 unused4 Execution err Set by an out of range parameter, or non-completion ofsome command due a condition such as an incorrectoperating mode.5 Command err Set by a command syntax error, or unrecognizedcommand6 URQ Set by any key press7 PON Set by power onThis status byte is defined by IEEE-488.2 (1987) and is used primarily to report errors in commands receivedover the communications interfaces. The bits in this register stay set once set and are cleared by reading themor by the *CLS command.LCR bit name usageSTATUS BYTE0 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 ofvalues for the present range.4 Overrange Set when a measurement is above the nominal range ofvalues for the present range.5 Out of Range Set when the unit is unable to make a validmeasurement on the current range.6 unused7 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 readingthis status byte or by the *CLS command.4-11
