Measurement Methods

1. Take off the protective cap from metal probe.
2. Press OFF/ON button. Tester displays 0.
3. ①quick testing: Water the soil with distilled water before testing. Make sure the water can go 10 cm deep the least. Best humidity is 70%-80%. Insert the metal probe into soil vertically and clockwisely, to about 6-8 cm deep. Make sure the soil has thorough contact with metal probe. After about 6 seconds, the tester will display the measured value.Tightness of soil will affect measuring result. Multiple tests at the same and different points should be performed and take the average as final result.
②accurate testing: Use a 200ml beaker container, mix dried soil with distilled water at the ,stir and make it into a mud form. Put the metal probe into the mud about 6-8CM deep. About 6 seconds, the tester will display the measured value.
4. Wipe the metal probe with towel or tissue paper after each test. Make it clean and dry, till the display shows 0.
