5.19.1 Entering the Calibration Mode
To test/calibrate the hardware, the Direct Board Control Enable checkbox must be checked.
This will present the warning depicted in Figure 5-42.
Figure 5-44: Direct Board Control Warning
When the
Direct Board Control Enable
mode is selected, any changes made on this tab will
be written directly to the board. The Warning light on the analyzer’s front panel will blink red,
notifying the user of this condition.
Direct board control will automatically be disabled if the user changes to
any other screen in the application program. However, it will not
automatically be disabled should the application program be exited directly
from the
Maintenance
screen without first removing the checkmark from
this box.
IMPORTANT: If the analyzer is left in direct board control enable mode, no
outputs will be updated during an analysis, so it is essential that this
checkbox be unchecked before exiting the application program. The
Maintenance screen allows the user to calibrate and test the analog
outputs, test the discrete outputs, and test the Optical Encoder.
