For an accurate calibration, it is recommended to wait a minimum of 15 minutes to ensure conditio-
ning of the probe. Keep the protective cap on during polarization and remove it for calibration and
measurements. Follow the calibration procedure.
Conditioning:
Before proceeding with the calibration make sure the probe is ready for measurements. Reinstall the
plastic protective cap over membrane end. Reconnect probe to meter and allow probe to polarize.
