18. With the ZnCl hold active, check the third line of the display. Exactly
1.812 g/ml should be displayed.
Adjust the density slope correction factor if necessary (DAC 049003).
Return to the main screen. The display will update in approximately
three seconds. If the displayed value is not 1.812 g/ml, observe how far
off the value is. Make another adjustment to the slope correction factor
(DAC 049003). Return to the main screen and wait for the screen to
update. Repeat this process until the third line of the display is exactly
1.812 g/ml.
19. Clear the ZnCl hold (DAC 9). This will return the gauge to normal
operation.
20. The displayed density should then be 1.000 g/ml.
The gauge is now calibrated for use of water as the carrier.
Note This calibration will be valid as long as the detector is not moved or
removed from the housing.
