9 Note of MODE3: Function mode CALIBRATION: The meter could automatically recognize the solution, and calibrate the reading to ms or 1413 μs. SET TDS FACTOR: To set the factor for the TDS calculation from the conductivity reading. Default setting is SET ATC FACTOR: To set the temperature compensation factor. Default setting is 2.1%. RESET: The meter will be reset to the factory setting. Push the key and select the RESET function. The previous Calibration information of the user will be deleted. The TDS FACTOR will be The ATC FACTOR will be 2.1% The Temperature UNIT will be. NOTE: CALIBRATION, SET TDS FACTOR and SET ATC FACTOR: More details in the Measurement. Using the backlight When it is difficult to see the LCD in the dark, you can turn on the backlight by pressing the Note: key. Turning on the backlight consumes energy and shortens battery life. Entering numeric values If the user want to set the parameter value and the meter is already in the setting modes, push the key once to increase the value, hold down the key to 8 / 16

10 continually decrease the value. Auto Power-off The meter will automatically power off without any operation for 8 min. Measurement This section describes the method of measurement. Preparation To make sure that the electrode is not stained or damaged. According to your applications, the standard solution will be helpful to the accurate reading. Do not use the instrument near any noise source. Battery Installation This instrument is operated by batteries. You can use AAA alkaline batteries or AAA NiMH rechargeable batteries. Perform the following procedure to insert batteries in the meter. 1. Turn the screws on the battery cover counterclockwise and remove the cover. 2. Install 2 AAA alkaline or 2 AAA nickel metal hydride batteries. 3. Make sure that the batteries are installed in the correct polarity. 4. Put the battery cover back. 9 / 16

11 Connect a probe 1. Plug the probe into the meter. 2. Push and turn the Plug tight nut to tighten. Measurement 1. Push the key and select the scale. 2. Push the key to confirm the selection when scale icon flash. 10 / 16

12 3. Put the probe into the solution and shake the probe gently to remove bubbles from the surface of the electrode. 4. There should be above 3cm from the probe bottom to the beaker bottom. 5. icon will display when the readings are stable 6. Record the readings. 7. Put the electrode out of the solution, and rinse it with deionized water. 11 / 16

13 Calibration 1. Same as the measurement, put the electrode into the standard solution (12.88mS, 1413uS) until the readings are stable. 2. Push the key to select the calibration function and Push key to confirm. 3. When the procedure is completed, End will be displayed. 4. The meter will return to measurement mode automatically. 12 / 16

14 Set the Factors Two factors could be modified by user: TDS Factor, and ATC Factor. 1. Push the key to select the SET TDS FACTOR or SET ATC FACTOR function and Push key to confirm it. 2.

16 It has been software optimized. In the range: 10.0uS 100.0mS, the 1% accuracy can be achieved. In the other range, the accuracy is around ±1.5%. At both Endpoints, the accuracy is ±2%. Appendix * If you do not know the temperature coefficient of your solution you can determine the correct value using the formula in Appendix Calculating Temperature Coefficients. Calculating Temperature Coefficients To determine the temperature coefficient of your sample solution use this formula: TC = 100 x CT2 CT1 CT1(T2 25) CT2(T1 25) TC = Temperature coefficient CT1 =Conductivity at Temp. 1 CT2 = Conductivity at Temp. 2 T1 = Temp. 1 T2 = Temp = 25 C A controlled temperature water bath is ideal for this procedure. 1. Immerse the probe into a sample of your solution and adjust the temperature coefficient to 0% (that is, no compensation) by performing the following: 2. Wait for 5 minutes. Note T1 and CT1 (conductivity at T1). 3. Condition the sample solution and probe to a temperature (T2) that is about 5 C to 10 C different from T1, and note the conductivity reading CT2. NOTE: Record your results for future reference. Ideally T1 and T2 should bracket your measurement temperature, and should not differ by more than 5 C. 4. Calculate the temperature coefficient of your solution according to the formula shown above. 5. Enter the temperature coefficient you calculated into the meter. 15 / 16

17 The calculated temperature coefficient will now be applied to all the meter readings. To determine the conductivity to TDS conversion factor for your solution: Appendix 1. Factor the conductivity to ppm TDS conversion factor. Multiply conductivity by this factor to get ppm TDS for the type of TDS reading needed a formulation that most closely represents the conductivity to ppm relationship, on average, for naturally occurring fresh water. 3. TDS Your Material These columns are for you to write in your application-specific conductivity-to-ppm values and conversion factors for future reference.
