Instruction:
Please install the batteries before using, remove the probe protector
1, light measurement
A. Press the ON button to turn on the instrument
B. Align the highest point of the light source sensor window.
C. The current intensity of the light will be displayed on the LCD monitor.
Tips; Please do not block the light or shadow to the light sensor manufacturing

2, PH measurement range
A. Press [PH / TEMP] button on the back to the PH value.
B. Insert the probe vertically into the soil, test as soon as possible. Do not insert  too deep, in case damage plant’s roots.
C. Press [ON] button to start the measurement.
D. PH value of the test will be displayed on the LCD screen
E. Test many times to get  the exact measurement value.
Tips; 1 probe vertically inserted, in the middle of the edge of the plant stems.
       2 Gently push the soil survey in order to avoid damage to the probe.
       3 If the measure is too dry or fertile soil can not be measured accurately PH value, the user can sprinkle a little water, after half an hour measured again.
3, moisture measurement

A Press the [PH / TEMP TEMP] button on the back
B vertically insert into the soil as much as possible. Do not insert  too deep, in case damage plant’s roots.
C Press the ON key to start the measurement
D test soil moisture values ​​will be displayed on the LCD screen.
E  Test many times to get  the exact measurement value.

4 Temperature measurement;
A When test the  humidity, soil moisture value will be  displayed on the LCD.

B Press [℃ / ℉ OFF] button to set the humidity display is ℃ or ℉.
Tips: If the user does not put the probe deep into the soil, then LCD shows the exact 

temperature of the external space environment.
