75% calibration
1. After the 33% calibration, plug the sensor
into the 75% salt bottle.
2. Press SET to enter the 75% calibration.
3. "CAL" and the calibration value (75.2%, if at
25°C) will blink on the LCD with the current temperature shown
on the left side of the display.
4. The meter is now calibrating and will finish in approximately 60
minutes (blinking stops). The meter will automatically return to
the normal mode.
NOTE: Single point calibrations can also be performed. To calibrate
33% only, press CAL/ESC and stop after the 33% calibration is
completed. To calibrate 75% only, press ▲/DP WB or MXN/AVG/▼
within 5 minutes of initializing the 33% calibration.
