3.3 Precautionary labels
Read all labels and tags attached to the instrument. Personal injury or damage to the instrument
could occur if not observed. A symbol on the instrument is referenced in the manual with a
precautionary statement.
Electrical equipment marked with this symbol may not be disposed of in European
domestic or public disposal systems. Return old or end-of-life equipment to the
manufacturer for disposal at no charge to the user.
3.4 Product hazards
C A U T I O N
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the
personal protective equipment appropriate to the chemicals that are handled. Refer to
the current safety data sheets (MSDS/SDS) for safety protocols.
C A U T I O N
Chemical exposure hazard. Dispose of chemicals and wastes in accordance with local,
regional and national regulations.
Section 4 Preparation for use
Prepare the probe as follows.
1. Rinse the probe with deionized water. Blot dry with a lint-free cloth.
2. Make sure that the meter has the correct date and time settings. The service-life time stamp in
the probe comes from the date and time settings in the meter.
Note: Some meters automatically open the date and time settings when the meter starts for the first time, or
after battery replacement.
3. Connect the probe to the meter.
Section 5 Calibration
The procedure that follows is applicable to meters that can connect to Intellical conductivity 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.
• Do not dilute conductivity standards or samples.
• The meter shows the conductivity standard solution to use for calibration. If necessary, change the
standard solution in the probe settings menu.
• The conductivity value changes with temperature. The default probe settings apply a temperature
correction to adjust the conductivity measurements to the value at 25 °C.
• Use the default calibration options or change the options 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.
