9.2.2.4 DAC Error Output
Note:
Default: Minimum Output
The user may select from among three states to be output when a condition is encountered
which causes the Anatel A643a to abort its current analysis. This fixed signal is global for all
analog outputs and can be used externally to report an alarm condition.
Note:
In the Calibrate mode, the analog output reflects on-line values. A zero-scale analog output
indicates the instrument is off-line; a full-scale output indicates an error condition.
To specify the DAC Error Output :
1) With the Analyzer’s Analog Setup Menu displayed, use the Up and Down Keys to
specify DAC Modes .
2) Select DAC Err Output and press Enter to display its parameter screen.
3) Use the Up and Down Keys to specify the desired setting:
4) Press Esc to return to the DAC Modes Menu . Select DAC Cal Output to enable that
feature, if desired. When “Active,” an analog signal proportional to each analysis result
is sent to an external DAC Module during calibration.
