Description:
1. Power input terminal1: 220V, terminal 2: 0V, terminal 3: earth
2. 4-20mA output terminal 4: -mA, terminal 5: 4-20mA
3. Electrode terminal 6: RED [T(R)], terminal 7: Violet [CELL(V)], terminal8: YELLOW [NET(Y)], terminal 9: Green [CELL(G)]
4. Operating Instruction
1) Put the instrument on the working table and fix the display unit.
2) After correctly connecting the electrode wire, power supply wire, input wire and output wire according to the diagram of wire connection on back panel, connect the power supply.
3) Put the electrode into the tube with water, then power on.
4) Coefficient set:
4.1) Press SET key, C=X.XXX will be displayed.
4.2) Press“↔” key, move the point.
4.3) Press“↕”key, change the displayed value unless it is the coefficient. (Coefficient is on the electrode lead wire.)
5) 4-20mA
5.1) Press SET key, XXXX will be displayed. Press“↔”and“↕”, correspondent values will be displayed. E.g. if maximum value is 20mA, 4-20mA will be output in the range of 0-20.00μS/cm.
5.2) Press SET key again, then measurement is functioned.
Note:
Ø That the last figure is flashing means it is under SET.
Ø Press SET key to enter into the below function window.

1. Attentions
1) The cable for testing the electrode should be special cable. If it is longer than factory length (5m), please confirm the length when place the order. For a good measurement accuracy, please remember to use special cable.
2) The measurement signal for conductivity is weak. In order to avoid interference or break the meter, the electrode cable should not be bound with any other cables.
3) Absolutely correct connection is the must, as the meter is sensitive.
4) Relay is preferred for alarm output to secure the safe working.
2. Electrode Installation (refer to below illustration)
