Calibration Mode

CO2 calibration

1. Place the meter in an outdoor area with well

ventilated air. Turn on the meter and hold down

"CAL" and "q" simultaneously to enter CO2

calibration mode. 400ppm and "CAL" are blinking

on the LCD while performing calibration (Fig.5).

2. Wait about 5 minutes until it stops blinking and

the calibration completes automatically and back

to normal mode.

3. To abort the calibration, turn off the meter at any

time.

Humidity calibration

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

down "CAL" and "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 "ENTER" 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.
