Option Description
Data introduction Manual probe constant introduction.
Theoretical calibration The probe calibration data is replaced at 25 °C
(77 °F).

6.1.2 Calibration procedure

This procedure is for general use with liquid calibration solutions. Refer
to the documents that are included with each probe for additional
information.
Note: Solutions should be stirred during calibration. For more information about the
stirring settings, refer to Change the stirring settings
1. Pour the buffers or calibration solutions into the labeled calibration
beakers.
2. From the main menu use the
CALIBRATION parameter. Confirm.
3. If required select the Operator ID (1 to 10) and confirm.
4. Rinse the probe with deionized water and put the probe into the first
calibration beaker. Be sure that there are no air bubbles in the
membrane.
5. Push to Start calibration.
6. Push to measure the first calibration solution.
The next calibration solution is shown.
7. Rinse the probe with deionized water and put the probe into the
second calibration beaker. Be sure that there are no air bubbles in
the membrane.
8. Push to measure the second calibration solution.
The next calibration solution is shown.
9. Rinse the probe with deionized water and put the probe into the third
calibration beaker. Be sure that there are no air bubbles in the
membrane.
10. Push to measure the third calibration solution.
When the calibration is good, the display briefly shows Calibration
OK and then returns to the main menu.
Note: When a printer is connected the print menu opens and the result can be
printed.

• pH-the slope and offset values are shown alternating with the
deviation (in %) and calibration temperature.
• ORP-the measured mV value and calibration temperature are
shown.
• Conductivity-the cell constant and calibration temperature for each
standard are shown.
6.1.4 Set the calibration reminder
The calibration reminder can be set between 0 to 23 hours or 1-7 days
(default 1 day). The display shows the remaining time to the new
calibration.
Note: When 0 days is selected, the calibration reminder is turned off.
