Remaining,” or “AUTO DISPENSE <OFF>”
depending on which dispensing method was last
chosen in the auto dispense menu.
Normal Operation
Note
On initial start-up, the purity meter
may display “...MΩ-cm or uS/cm.” This
is caused by air in the cell and should
be replaced by a resistivity reading
almost immediately. If the dots aren’t
replaced by a value after one minute,
refer to the “Troubleshooting” section
of this manual.
Note
Do not turn off the NANOpure
DIamond Analytical during non-work
hours. Doing so will allow bacterial
growth and other contamination of the
water in the system. As a result, the
system will require a rinse-up period at
the beginning of the work day to
achieve high quality product water. We
recommend using the Standby Mode.
Note
From the normal recirculating mode
when the display is showing purity,
press ENTER to show the current tem-
perature. The temperature will display
for about 5 seconds before returning
to the normal recirculating mode.
Note
Press any switch except ENTER to
stop dispensing. Display will read,
“Auto Dispense Interrupted by User.”
