Stage 1
- this is an in-line test.
The procedure follows:
• Measure the temperature of the water and the absolute
conductivity readings. The measurement must be an in-line
measurement. Results may be verified using a laboratory
method.
• The temperature should be rounded down to the nearest 5 °C.
Look up the corresponding conductivity value in the table on
the next page.
• If the measured conductivity is lower than the conductivity in
the table, then the water meets the USP requirements.
• Otherwise, proceed to Stage 2 testing.
Stage 1
steps:
Press
from the keypad.
• An instruction prompt will pop up.
• Using measurement technique outlined in direct measurement, place probe into sample.
• Press
.
• The user may Edit the USP factor (to provide a margin of error) or compare measurement results directly to
the standard (100%). “
Please wait ...
” will appear on display and the measurement is compared to the
standard values.
• At the conclusion of the test period the results will be displayed.
• The user may View the results as a report. Press
.
• A copy of the sample results may also be saved. Press
. This may be printed using
HI 92000
software.
