Operating ManualEcoTestr CTS1 Pocket Tester• The batteries have been pre-installed. Please pull out theinsulating paper before first-time use. When replacing batteries,the positive side (+) of every single battery must face up. Pleasecheck the detail in "Battery Installation" section.• Before shipment, the factory adds in some water droplets to thetester's cap. This ensures that the probe keeps its sensitivity. Thispractice of adding several drops of water into the cap to keepsensor activation is highly recommended when storing the tester.Calibration1. The tester only needs to be calibrated for conductivity, thenpress to switch to Conductivity → TDS→ Salinity.2. Press and switch to conductivity mode, rinse the probe indistilled water and shake off excess water.3. Long press to enter calibration mode; short press to exit.4. Dip the probe into 1413 μS/cm calibration solution. Stir gently,leave it to stand. Wait for the measurement stability icon () toappear and stay on the display, then short press to completethe 1st calibration. Tester returns to measurement mode, andcalibration icon “M” appears on the bottom left side of display.5. Rinse probe in distilled water and shake off excess water. Repeat#3 and #4 to complete 2nd calibration in 12.88 ms/cm calibrationsolution. Tester returns to measurement mode, and calibrationicon “M” and “H” will appear on the bottom left side of display.1. Short press to turn on the tester, short press to switch tothe desired measurement mode (Conductivity, TDS or salinity).Rinse probe in distilled water and shake off excess water.2. Stir the probe in the sample solution gently, leave it to stand. Waitfor the stability icon () to stay on screen, then take the reading.3. Rinse off the probe thoroughly in distilled water after each test.• If probe response is slow, we recommend soaking the probe in12.88 mS/cm solution for 15 to 30 minutes to restore itssensitivity. Re-calibrate the tester after rinsing. Please addseveral drops of water into the cap to keep sensor activationwhen storing the tester.• The tester adopts 1413 μS/cm and 12.88 mS/cm standardcalibration solutions. User can use 1 or 2 point calibrations asneeded. For most circumstances, calibrating in 1413 μS/cm to• Restore to factory default (P5) description: Select "Yes" in P5 torestore the calibration to the theoretical values and parametersetting to original values. When tester's calibration ormeasurement performs abnormally, this function can be adoptedso the tester returns to factory default setting and then users canconduct calibration or take measurements again.Conductivity of the solution TDS factor (P2)0 to 100 μS/cm 0.60100 to 1000 μS/cm 0.711 to 10 mS/cm 0.8110 to 100 mS/cm 0.94• Conductivity range (P1) description: Aut - all ranges: 0~2000μS/cm, 0.01~20.00mS/cm. Once the readings are greater than2000 μS/cm, the unit will automatically become mS/cm.1 mS/cm = 1000 μS/cm. μS - only μS/cm range: 0~2000 μS/cm;mS/cm - only mS/cm range: 0.01~20.00 mS/cm.• TDS factor (P2) description: User can adjust TDS factor byexperimental data or experience.

Short press to turn on; long press to turn off.2. When turned off, long press to enter setup mode.3. In mode setting , short press to change parameter.1. In measurement mode, long press to enter calibration mode,short press to switch Conductivity, TDS and Salinity.2. In calibration mode, short press to confirm calibration.3. In mode setting, short press to confirm parameter selection.MEAScomplete 1st point calibration will meet testing requirements.• The tester has already been calibrated before leaving factory.User can use the tester immediately or can test it in the standardcalibration solutions to evaluate its accuracy. If error is large,calibrate the tester before using.• We recommend replacing the calibration solution after 5 to 10calibrations to maintain accuracy.• The surface coating of probe sensor bar is firm platinum blackprocessed with special techniques. It improves measuringperformance and coating firmness. If the probe is contaminated. itcan be gently brushed with a soft brush in warm soap water oralcohol.Self-Diagnostic MessagesSymbol Self-diagnosisinformation How to fix• Check if calibration solution iscorrect.• Check if probe is damaged.is pressedbefore measurementis stable ( appearsand stays)Wrong calibrationsolution, or measuredvalue is not within therange of the testerWait for the measurement stabilityicon () to appear and stay,then pressTMSpecial NotesMeasurement (Conductivity, TDS & Salinity)Notes:Setting the ParameterNotes:
