11. When standardization is complete, recall the water signal value (DAC
128003). Record this value.
Note The water signal value will be displayed with E4 at the end of it.
The calculation in the next step will be easier using a whole number.
To record this value as a whole number, move the decimal to the right
four places. For example, 3.123E4 is 31230.
12. Calculate the ZnCl signal:
ZnCl
Value
For example, if the factor obtained in step 7 is 0.5077 and the water
signal value from step 11 is 31230, then:
13. Enter the calculated ZnCl value calculated in step 12 into memory
(DAC 133003).
Note Values in scientific notation (values greater than 99999) must be
entered differently. Enter the base first. Then press the decimal key to
bring up the E, which indicates the start of the exponent. Enter the
exponent.
14. Hold the output at the ZnCl signal value (DAC 137). The displayed
values will change.
15. Observe the process g/ml value on the third line of the display. It
should be near 1.812 g/ml. If it is below 1.6 or above 2.0 g/ml, it is
likely that an error occurred. Repeat this procedure.
16. Recall the density slope correction factor (DAC 049003). Record this
value.
17. Recall the carrier specific gravity (DAC 085003). Record this value.
Note The values recorded in steps 16 and 17 are required for
troubleshooting purposes. Keep these values handy.
