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.
Humidity calibration
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.
