Steps to use:

1. Press the on button to turn on:
2. Quick test method: First will be tested soil measuring point, with purewater (or distilled water) poured through at least 10CM depth (the besthumidity 70-80%),and then the instrument metal probe, verticallyclockwise inserted in about 8cm depth of wet soil, so that the soil andprobe metal surface easy and uniform contact, response time is about 10seconds or so, the number displaved by the instrument, That is the actuameasurement value, The tightness of the soil will directly affect the errorof the measurement value, so it is required that the multi-pointmeasurement of the above method must be carried out at differentmeasuring points to order the average value.
3. lmmediately after each measurement, clean the surface of the metaprobe with a paper towel or cleaning cloth until the instrument returnsto a state that displays zero values.
4. Calibration method:under normal circumstances,before theinstrument leaves the factory, the factory has calibrated, the user doesnot need to recalibrate.

Notes on the instrument:

1. The instrument metal probe inserted in the soil or paste soil (otheimeasured media) should not be too long, so as to avoid oxidation andwater seepage,thereby damaging the metal surface and internalstructure of the probe, resulting in inaccurate or unstable measurementdata of the instrument, At the end of each use of the instrument, it isnecessary to use a grinding cioth (clean cloth)or wet paper towel tocompletely remove the residual objects on the surface of the metaprobe in time, and blot the surface of the metal probe with paper towels
2. After use, press the switch key to shut down, clean the electrode toreduce pollution after saving.
3. When the instrument is not in use,it is necessary to put on theprotective cap on the metal probe, do not rub the surface of the metalprobe directly with your hand, and keep it clean and dry, away frommagnetic objects and other metal objects.
4. During use, insert the electrode into the soil to avoid collision withhard objects as much as possible.
5. After the low battery alarm, replace the battery in time to ensure thenormal use of the product
