Calibrating an Orifice Tube
5. Install the orifice tube onto the sample port (the instructions on page
how to install an orifice tube).
If you have a camera installed on the analyzer, adjust the lens to display the orifice.
6. Place a beaker (not the sample beaker you washed for the calibration) on the sample
stand and raise the stand. Refer to User Interface, page 2-3, if you need assistance on
raising and lowering the sample stand.
7. Clean the installed glassware (orifice tube, electrode, and stirrer) externally:
a. Fill a squeeze bottle with clean, filtered electrolyte or water.
b. Using the squeeze bottle, thoroughly rinse each piece of glassware.
c. Lower the sample stand and remove the beaker.
8. Rinse the clean sample beaker with filtered electrolyte or water.
9. Fill the sample beaker with the amount specified for the beaker you are using (refer to
the reference material booklet); allow enough room at the top to prevent overflow
when glassware is submerged.
10. Place the beaker on the sample stand; position the electrode next to the orifice tube so
that it will be submerged in the beaker.
11. Raise the sample stand using the knob on the front.
Be sure the stirrer does not strike the bottom or sides of the beaker when raising
the sample stand. The stirrer will not operate if it comes in contact with the
beaker.
