6.6 Conductivity calibration
CAUTION
Potential puncture hazard! Contact with the exposed needle could cause serious
injury. Use extreme care when installing and removing the sample bottles.
Conductivity calibration ensures the accuracy of the conductivity values reported by the
PAT700 TOC analyzer. A conductivity calibration consists of verifying the conductivity meter
using a precision resistor. The cell constant is adjusted to the value of the conductivity
standard, and therefore is always within ±2%. If the new calibration is greater than ±10% of
the factory calibration or ±5% of the previous user calibration, the calibration is unacceptable
and a new calibration is required.
1) Allow the conductivity calibration standard to warm to room temperature.
2) At the home screen, touch the << icon to open the sliding toolbar.
3) Touch the setup icon.
4) Touch the bottles icon, then touch the conductivity calibration tab.
5) Make sure a checkmark appears in the use calibration resistor checkbox. If a
checkmark is not present, touch the checkbox to enable use of the calibration
resistor.
6) Press the return icon to return to the setup dialog box, then touch the return icon
again to return to the home screen.
