In electric-controlled plate, to represent water purifier in the TDS situations for purify front and back aqueous solutions.
In the utility model embodiment, the TDS situations of the solution of different quality are replaced using the resistance of different resistance values,
The resistance value that open and close by controlling switch to access in circuit is different, to ensure to detect in water purifier electric-controlled plate
The consistency of hardware cell in journey.Wherein, the water purifier electric-controlled plate used in the present embodiment is model DR232 electric-controlled plates, the electricity
It controls on plate with microcontroller and its relative program and circuit.
In the test process of the prior art, TDS probe wires are connected to the electric-controlled plate, TDS probe wires are placed on only
To detect the aqueous solutions parameter at the node at the different nodes of hydrophone, it is not cleaned for example, TDS probe wires are placed on
To detect the TDS values of raw water at water purifier node；Or, TDS probe wires are placed at the water purifier node of purified treatment
To detect the TDS values of pure water.In the present embodiment, the solution that different quality is replaced by using the resistance of different resistance values, is connect
The resistance entered to the electric-controlled plate is bigger, and the corresponding aqueous solutions parameter value of resistance is smaller, is linked into the electric-controlled plate
Resistance is smaller, and the corresponding aqueous solutions parameter value of resistance is bigger, wherein the solution parameter is PPM values.By different resistances
After the resistance of value is handled by normal water purifier electric-controlled plate, the PPM values of corresponding water quality are obtained, as shown in table 1 below, table 1 is said

It closes there are one detected PPM values in the state of closure or disconnection or two is not explicitly shown in rational error range,
Then illustrate that electric-controlled plate breaks down, needs to be detected to debug.Specifically, if first resistor and second resistance are 5k
Ω, series connection be linked into electric-controlled plate jointly, if the PPM values that electric-controlled plate detects between 38~42, if while first resistor and
Electric-controlled plate is linked into one of in second resistance, the PPM values that electric-controlled plate detects at this time are between 78~81, then explanation should
Electric-controlled plate works normally；, whereas if detected PPM values there are one or two not within the scope of the reasonable error, then
Illustrate that electric-controlled plate breaks down, needs to be detected to debug.When first switch disconnects, first resistor and second resistance
Series connection, the all-in resistance of the tooling is 10k Ω at this time, and the PPM values on electric-controlled plate display screen are shown as 39；When first switch is closed
When, second resistance is short-circuited, and the all-in resistance of the tooling is 5k Ω at this time, and the PPM values on electric-controlled plate display screen are shown as 79, then say
Bright electric-controlled plate normal work.
