Instructions
Install the battery before use， remove the probe protective sleeve
1， light measurement
A. Press the ON button to turn on the instrument
B. Alignment highest point source light sensor window.
C. The current intensity of the light will be displayed on the LCD monitor.
Note: Please do not block light or create a shadow to the light sensor
 
2， PH measurement range
A. The back of [PH / ℃] button to push to PH position.
B. probe vertically into the soil needs to be tested as soon as possible.
C. Press the [ON] button to start the measurement.
PH value D. test will be displayed on the LCD
E. Multi-measurement times needed to draw firm value.
note:
1. vertical insertion probe edge in the middle of the plant stems.
2. Gently push into the soil， to avoid damage to the probe.
3. If the soil is too dry or fertile measured can not be measured accurately PH value， the user can sprinkle a little water， half an hour before the measurement again
 
3， moisture measurement
A on the back of [PH / ℃] push button to the position ℃
B as vertically into the soil.
C Press NO key to start the measurement
D test soil moisture values ​​will be displayed on the LCD screen.
E several times more than the exact value measurement results needed.
 
4. Temperature measurement;
A When measuring humidity at the same time， soil temperature will be simultaneously displayed on the LCD screen.
B Press [℃ / ℉ OFF] button to set the humidity display is ℃ or ℉.
Note: If the user does not put the probe into the soil， it shows the exact temperature of the external space environment.
