Using the Status Register
The status register monitors the following multimeter status information:
– Subprogram complete
– High or low limit exceeded
– SRQ command executed
– Power turned-on
– Ready for instructions
– Error
– Service requested
– Data available.
When one of these events occurs, it sets a corresponding bit, in the status
register. The following list defines the meaning of each bit in the status register:
Bit 0 (weight = 1) Subprogram Complete--a stored subprogram has been
executed.
Bit 1 (weight = 2) High or Low Limit Exceeded--one or more readings have
exceeded the high/low limits specified for the Pass/Fail math operation. This bit
applies to both real-time and post-process math. (See
Bit 2 (weight = 4) SRQ Command Executed--the multimeter's SRQ command
has been executed.
Bit 3 (weight = 8) Power-On--a power-on sequence has occurred.
Bit 4 (weight = 16) Ready for Instructions--the multimeter has completed
execution of any previous commands and is ready to accept more commands.
(When using TRIG SGL or TARM SGL to initiate a group of readings with the input
buffer off, this bit can be used to monitor when all readings are complete.)
Bit 5 (weight = 32) Error--one or more errors have been logged in the error/
auxiliary register. Refer to
more information.
You can prevent any or all errors from setting the error bit in the status register
NOTE
using the EMASK command. Refer to the EMASK command in
more information.
