Status Structure
Measurement event status
The used bits of the measurement event register (shown in Figure 13-6) are described as
follows:
•
Bit B1, low limit 1 fail (LL1F)
— Set bit indicates that the low limit 1 test has failed.
•
Bit B2, high limit 1 fail (HL1F)
— Set bit indicates that the high limit 1 test has failed.
•
Bit B3, low limit 2 fail (LL2F)
— Set bit indicates that the low limit 2 test has failed.
•
Bit B4, high limit 2 fail (HL2F)
— Set bit indicates that the high limit 2 test has failed.
•
Bit B5, limits pass (LP)
— Set bit indicates that all limit tests passed.
•
Bit B6, reading available (RAV)
— Set bit indicates that a reading was taken and
processed.
•
Bit B7, reading overflow (ROF)
— Set bit indicates that the volts, amps, ohms or cou-
lombs reading exceeds the selected measurement range of Model 6514.
•
Bit B8, buffer available (BAV)
— Set bit indicates that there are at least two readings
in the buffer.
•
Bit B9, buffer full (BFL)
— Set bit indicates that the buffer is full.
