You can also check the device is working
correctly by testing it in saline as follows:
1. Immerse the probe vertically in a glass containing
clean water at room temperature. Resting the
probe in the middle of the bottom of the glass,
perform a measurement cycle and read the
result. It will probably be
the measuring range has been exceeded, as the
resistance of clean water is very high.
2. Next, add a small pinch of salt, mix it well with the
water, immerse the probe as previously stated
and perform the measurement cycle again. After
adding the salt, the result will change, which
is dependent on the solution concentration,
as salt decreases resistance (lower resistance =
lower results)
