5.4.2 Calibrate the conductivity monitor
Introduction
Two types of calibration can be performed:
•
Conductivity monitor - user calibration: Calibrates the conductivity cell constant.
•
Conductivity monitor - factory calibration: Restores the conductivity cell constant
to the factory default value.
This section gives instructions for both calibration procedures. The instructions apply to
both pre- and post-column conductivity monitors.
Maintenance interval
When to perform the two types of calibrations is as follows:
When to perform Calibration type
When the signal is unstable, or when you suspect that the
value is incorrect. User calibration
When user calibration fails. Factory calibration
Required material
The following materials are required:
• Luer-to-SNAP connector (see Luer-SNAP 3.2 connectors, on page 25 )
• Waste container
•
Syringe, 25 mL
•
Calibration solution, either a certified conductivity standard solution (1.0 M KCl) or
your own accurately prepared 1.00 M NaCl.
•
Distilled water
User calibration procedure
Follow the steps below to calibrate the conductivity monitor.
