3. Press the USB I/O button. Make sure that the USB flash memory drive is attached to the USB port, and
then press the Save System button.

Perform Annual Maintenance Tasks

Before calibrating the Analyzer, perform annual maintenance tasks as appropriate, such as replacing the
sample pump heads, UV lamp, and DI water cartridge. In particular, if the calibration coincides with the
Analyzer's annual maintenance, first replace the DI water cartridge before proceeding; for more information,
see "Replacing the DI Water Cartridge" on page 145.

Handling Standards

Because of the prevalence of both conductivity contaminants and organic carbon contaminants, sample
preparation and control is extremely delicate. Special handling of the standard solutions is required.
Store standards at approximately 5 °C (±4 °), away from light, in a box or solid-door refrigerator. Warm standards
to ambient temperature prior to starting analysis. Avoid touching the top of the vials to protect against
introducing foreign particles, TOC, and conductivity.
After following these steps, proceed either to "Performing a Single-Point Calibration" below or to "Performing a
Multi-Point Calibration" on page 120.

Disable Daily Download and Binary Input

If you will be performing calibration or other system protocols at a time when a daily download of history data
may occur, temporarily disable the download to ensure the system protocol activities are not interrupted.
1. Select the Data tab.
2. Press the Setup History button.
3. Press the Daily Download button and select Off.
4. When you are finished performing calibration or other system protocols, reset the Daily Download
value to On.
If you use the Binary Input function, disable Binary Input.
1. Select the I/O tab.
2. Press the Binary Input button.
3. Press the Binary Input Off button.
4. When you are finished performing calibration or other system protocols, press On to reset the Binary
Input function.
