Put the probe into 222mV calibration solution and shake it gently. 3. Wait until the reading is stable, then long "MODE/CAL" for 5 seconds and release; CAL is displayed on the screen, then a value flash 3 times on the screen, when the value starts to fiash, "MODE/CAL" button ( lf the flashing value is higher than 222mV ) or "HOLD/TEMP" button ( lf the flashing value is lower than 222mV ). 4. After adjusting the displaying value to 222mV then release the button, waiting the reading stop flashing,the calibration is finished, rinse off the probe with water. Storage: Buffer solutions should be stored in a dark, cool place (not in the refrigerator and at temperatures no higher than 25°C) away from direct sunlight to prevent photochemical degradation. In addition, buffer calibration solutions should be protected from carbon dioxide from the air and stored in tightly closed containers.
