4. Rinse the probe in one of the containers. Gently stir the
probe.
5. Dip the rinsed probe into the other container. Tap the
probe on the bottom of the container to remove air

6. Turn the meter on. In Normal Mode, press MODE
continuously to select the mode as CON.
7. Press CAL to enter Calibration Mode. The probe au-
tomatically detects the conductivity value of the
solution. The value will flash on the LCD.
8. Wait for the measured conductivity value to stabilize. If
you have enabled the Ready function in P6.0, the ready
icon will appear on the upper left corner of the LCD
when the calibration is stable.
9. Press ▲ or ▼ to adjust the value on the primary display
to match the value of the standard buffer. There are two
options:
 To input the value based on current temperature, the
Temperature Coefficient (page 23) must be 0.0.
 To input the value based on 25°C, refer to APPENDIX C
on page 62
to select the temperature coefficient value.
