HOW TO USE
Step1: Switch to one of the three different measurements you want (moisture, pH, light).
Stick the probe into the soil about 5 to 10 cm (2 to 3 in).
Do not force it into very hard soil or touch hard objects since it will be easy to damage the probe.
If the soil is too dry the indicator will not move, you need to water it before testing.
It was not conceived to test pure water or other liquids. It can only be used to measure soil.
Step3: Adjust the position of the probe until the pointer on the dial swing slightly.
Step4: Give it 10 minutes to stabilize, and then heck moisture/pH/light level in the dial.
Step5: For a better lifetime, do not leave the meter in the soil, please wipe and clean the probe after each use.
