Use steps:
1. Press the on key to start the machine;
2(1). Precision test method: First, put the soil (it is recommended
that the soil be dried) and pure water or distilled water (it is
recommended that the Wahaha pure water) into a container according
to the ratio of water 2: soil 1 to make a uniform paste state. Then
the metal probe of the instrument is vertically inserted into the
soil of the container at a depth of 6-8cm, the response time is
about 10 seconds, and the number displayed by the instrument is the
actual measurement value. (This test method unified the soil
moisture and removed the influence of humidity factor on the test
result, which was close to the original value of the soil)
2(2). Quick measurement method: First, the soil measuring point to
be detected is poured with pure water (or distilled water) to a
depth of at least 10CM or more (the best humidity is 70-80%), and
then the instrument metal probe is inserted vertically clockwise
into the wet soil at a depth of about 8cm, so that the soil and the
probe metal surface are easily and evenly contacted, the response
time is about 10 seconds. The number displayed by the instrument is
the actual measurement value. The tightness of the soil will
directly affect the result of the measurement value, so it is
required that the multi-point measurement of the above method must
be carried out at the position of different measurement points to
order the average value.
(The value of this test is closer to the value of the soil in its
current state, taking into account environmental factors that can
affect the measured value)
3. After each measurement, the surface of the metal probe should be
cleaned with a paper towel or cleaning cloth in time until the
instrument returns to a zero value state.
4. Calibration method: under normal circumstances, the instrument
has been calibrated before leaving the factory, and the user does
not need to recalibrate. Instrument precautions
1. The instrument metal probe inserted in the soil or paste soil
(other media to be measured) should not be too long, so as to avoid
oxidation and water seepage, thereby damaging the metal surface and
internal structure of the probe, resulting in inaccurate or
unstable measurement data of the instrument. After each use of the
instrument, the residue on the surface of the metal probe must be
thoroughly removed with a paper towel or cleaning cloth in time,
and the water on the surface of the metal probe must be dried with
a paper towel.
2. After use, press the switch key to shut down, clean the
electrode and save it after reducing pollution.
3. When the instrument is not in use, do not rub the surface of the
metal probe directly with your hand, and keep it clean and dry,
away from magnetic objects and other gold objects.
4. During use, insert the electrode into the soil as far as
possible to avoid collision with hard objects.
5. After the low power alarm, replace the battery in time to ensure
the normal use of the product.
