Section 5 Calibration
The procedure that follows is applicable to meters that can connect to Intellical LDO probes. Refer to
the applicable meter documentation for meter operation and probe-specific settings.
5.1 Calibration notes
Read the notes that follow before calibration.
• Measure samples as soon as possible after collection.
• Remove the shroud before calibration. Refer to Remove or install the shroud on page 9.
• The factory calibration is sufficient for most applications. If necessary, set the probe to use a
different calibration option in the probe settings menu.
• Use the single display mode for calibration when more than one probe is connected to the meter (if
applicable).
• Calibrate the probes and verify the calibration regularly for best results. Use the meter to set
calibration reminders.
• The calibration data is stored in the probe. When a calibrated probe is connected to a different
meter with the same calibration options, a new calibration is not necessary.
• Air bubbles below the sensor when in solution can cause a slow response or error in the
calibration. Make sure to remove air bubbles during calibration.
• The meter uses the slope value shown at the end of the calibration to monitor the condition of the
sensor cap.
