Model 2700 Multimeter/Switch System User’s Manual Status Structure 11-13
• Bit B1 — Not used.
• Bit B2, Query Error (QYE) — Set bit indicates that you attempted to read data
from an empty Output Queue.
• Bit B3, Device-Dependent Error (DDE) — Set bit indicates that an instrument
operation did not execute properly. Some of the errors specific to the Model 2700
that will set this bit include the following:
• Error +516: Battery backed RAM error — Data stored in RAM has been lost.
Replace the battery if frequent failures occur.
• Error +517: Cannot resume scan — Due to a card ID change, auto scan has
disabled. The scan will not resume after a power interruption. For details, see
“
Scan configuration — Auto scan,” page 7-21.”
• Error +520: Saved setup scancard mismatch — Settings for a user setup or
power-on setup do not match the switching module types presently installed.
For details, see
“Defaults and user setups,” page 1-20.
• Error +523: Card hardware error — Communication with the microprocessor
on a switching module card has been lost.
• Error +524: Unsupported card detected — The Model 2700 has detected an
installed Model 77XX switching module that is not supported by the current
version of firmware.
• Bit B4, Execution Error (EXE) — Set bit indicates that the Model 2700 detected
an error while trying to execute a command.
• Bit B5, Command Error (CME) — Set bit indicates that a command error has
occurred:
• IEEE-488.2 syntax error – Instrument received a message that does not follow
the defined syntax of the IEEE-488.2 standard.
• Semantic error – Instrument received a command that was misspelled or
