DESCRIPTION
When an error has occurred, the ERROR indicator light on the front panel of the unit turns on. Error Status
Query (
the unit responds with one of the following error codes:
: No error has occurred.
E000
: Invalid device dependent command (IDDC) due to a command syntax error.
E001
: Invalid device dependent command option (IDDCO). A command parameter was out of range or
E002
missing.
: A Channel Configuration Error indicates that a channel has been inappropriately configured, either
E004
because the channel is not present or because the specified channel type is not compatible with the card type
installed.
: A Calibration Error occurs when the card calibration has failed or has been inappropriately calibrated.
E008
: A Trigger Overrun Error occurs when more than one trigger event occurs for a given trigger state or when
E016
a non-expectant trigger event occurs.
: An Open T/C Error or Range Error, occurs when the hardware circuitry detects an open thermocouple, or
E032
when the software detects the A/D input has reached or exceeded its linearization.
: A Command Conflict Error indicates the issuance of a command that is in conflict with other commands
E128
that have been issued or the current configuration. This error usually occurs when a command is issued that
cannot be performed because of the current state of the unit. For instance, if the Set Scan Interval (
