Performing A Multi-Point Calibration - GE Sievers 500 RL Operation And Maintenance Manual

Chapter 6: Calibration and System Protocols

Performing a Multi-Point Calibration

Before performing a multi-point calibration, save the current Analyzer system settings, as described under the
section called "Preparing for Calibration" on page 115. If your configuration does not measure conductivity, you
will not be using the conductivity standard for this protocol.
When you are ready to calibrate the Analyzer, follow these steps:
1. If the Analyzer is taking measurements, press the Stop Analysis button.
2. Press the Menu button, select the Maintenance tab, and press the Cal/Ver/Validate button.
3. Press the Multi Pt Cal button.
4. If you have a Super iOS System, the Select Rinse screen appears. Otherwise, go to step 11.
5. Select one of the following rinse options, and then press the Next button.
• No Rinse
• Before
• After
• Before and After
6. If you have selected No Rinse or After, and there are vials in the Super iOS, remove them now. Press
Next to continue. Wait for the Analyzer to drain each of the Super iOS vial chambers (about 2 minutes).
7. If you have selected to run a rinse, the Analyzer will prompt you to do one of the following:
• Insert the Super iOS Rinse vial set into the Super iOS.
• Or, if using individual rinse vials, press Next for additional instructions. Insert the individual vials in
the Super iOS, and then press No Set to proceed.
8. Do one of the following:
• If you have a purchased vial set, insert the standards cartridge into the Super iOS System with the
label facing away from the Analyzer and press Next.
• If you have purchased individual vials rather than a vial set in a cartridge, confirm the value shown
on the Conductivity Standard label. Next, make sure the vials are inserted into the iOS System vial
ports in the following order:
Port 1 = TOC Calibration Blank
Port 2 = TOC Calibration Blank
Port 3 = TOC Calibration Standard (1.50 ppm KHP)
Port 4 = Conductivity Standard
Press the Next button, and then press the No Set button.
If the label of the Conductivity Standard shows a value of 25 µS/cm HCl, (or your configuration does
not measure for conductivity), press Next to continue.
