Manual calibration

The manual calibration is suggested to be done in

outdoor area with ventilating fresh air where CO2

level is around 400 ppm. Do not calibrate in places

crowded with people or close to where with high

CO2 concentration such as ventilating outlets or

fireplaces.

1. Place the meter in the calibration site. Turn on the

meter and hold down "CAL/ESC" and "p/DP/WB"

simultaneously to enter CO2 calibration mode.

400ppm and "CAL" are blinking on the LCD while

performing calibration. (Fig. 7)

2. Wait about 5 minutes until it stops blinking and

the calibration completes and back to normal

mode.

3. To abort the calibration, turn "RESET" over a

second.

1. Plug the sensor probe into 33% salt bottle. Hold

down "CAL/ESC" and "MNX/AVG/q" under

normal mode to enter 33% calibration. "CAL" and

calibrating value (32.7% if at 25°C) are blinking

on the LCD with current temperature at the left.

Meter is now calibrating, and will finish in about

60 minutes when "CAL" and humidity value stop

blinking.

2. After 33% calibration, plug the sensor probe into

75% salt bottle, then press "SET" to enter 75%

calibration. "CAL" and calibrating value (75.2%

if at 25°C) are blinking on the LCD with current

temperature at the left. Meter is now calibrating.

Wait about 60 minutes until blinking stops, then

calibration is completed and it returns to normal

mode.
