POWER OFF
To turn o󰀨 the meter press key for 3 seconds, the meter will switch o󰀨. The instrument cannot be switched
o󰀨 during calibration.
1. Switch on the instrument by pressing the key .
2. Rinse the electrode with distilled water and pat dry gently.
3. Immerse the electrode in the available Redox solution (es: 475 mV); wait for the stability.
4. Press CAL button (LED Blu backlight).
5. The instrument enters calibration mode and recognizes the Redox solution, with a certain
degree of uncertainty.
6. At the center of the display, the value ashes, in demonstration of the possibility, by the
user, to adjust this value by +/- 75 mV compared to what is shown on the display during
calibration. Make this operation, keep pressing MODE button. Initially the value will move by
units, then by tens.
Note: The value will only move upwards. If the initial value on the display is higher than the required
one (ex: 490 mV with respect to the 475 mV bu󰀨er), keep pressing MODE until the value becomes lower
than the desired (-75 mV with respect to the value shown on the display); at that point it will be possible to
reach the desired value by keeping MODE pressed.
7. Press to conrm and complete calibration.
8. Calibration is complete and the instrument automatically returns to measuring mode.
Note: Press at any time to exit calibration.
SENSOR MAINTENANCE
After long time dry storage, put and leave the probe in storage solution (or pH 4) for at least 30 minutes to
reactivate the sensor.
Conductivity 1 - Conductivity 5: • Store the sensor dry after each use, once rinsed
with distilled water.
• Never touch conductivity probe with paper or any
tools (expecially the internal part); for cleaning
purpose only rinse with distilled water. If touched
the probe may damage.
pH1 – pX4 - pH5 – pH5 Food – ORP5 – PC5 – PC6: • Rinse the probe with distilled water before each
use.
• Store the sensor into STORAGE Solution (or pH 4)
after each use, once rinsed with distilled water.
• Never store pH sensor in distilled water!!!
