User’s Manual
• Bit B7, Reading Overflow (ROF) — Set bit indicates that the volts or amps
reading exceeds the selected measurement range of the SourceMeter.
• 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 trace buffer is full.
• Bit B10 — Limit 4 - Contact Check (see Appendix F).
• Bit B11, Output Enable Asserted (Int) — Set bit indicates that the output
enable line is at digital low (asserted). The source output can be turned on.
• Bit B12, Over Temperature (OT) — Set bit indicates that an over tempera-
ture condition exists. The source output cannot be turned on.
• Bit B13, Over Voltage Protection (OVP) — Set bit indicates that the source
is being limited at the programmed limit level.
• Bit B14, Compliance (Comp) — Set bit indicates that the source is in com-
pliance.
• Bit B15 — Not used.
