In general, there are two electrode in a TDS detection probe, therefore, according to the number of TDS detection probes in water route to be measured
It can learn the number of electrode in water route to be measured.
For example, there is 2 TDS detection probes in water, then electrode sum is 4 in water, can be set as duty cycle threshold
25% or water in have 1 TDS detection probe, then in water electrode sum be 2, duty cycle threshold can be set as 50%.

Oxidation reaction and reduction reaction are quickly alternately, it is believed that oxidation reaction and reduction reaction do not occur, so as to reduce
The error of detection.When starting to detect the TDS values of water, the alternating voltage of two probes TDS1, TDS2 are respectively started, and each probe is certainly
Stabling current is formed between two electrodes of body.When electrode TDS1-1 is high level, TDS1-2 is low level, TDS2-1,
TDS2-2 is high-impedance state without output, and two electrodes popped one's head on TDS1 form stabling current, start the inspection of probe TDS1 at this time
It surveys.When electrode TDS2-1 is high level, TDS2-2 is low level, and TDS1-1, TDS1-2 are high-impedance state without output, are popped one's head in
Two electrodes on TDS2 form stabling current, start the detection of probe TDS2 at this time.Two TDS are avoided through the above way
Gathered data causes crosstalk to detection probe simultaneously, further improves the accuracy of testing result.
The above method provided in this embodiment can effectively prevent two electrodes of TDS detection probes that polarization phenomena occur, protect
Card probe long time stability work, not only reduces error, improves the accuracy of TDS detections, and do not cause two to water
Secondary pollution, brings great convenience for water quality monitoring.In addition, when there is multiple TDS detection probes in water route, it can also be ensured that more
