Calibration

1.Rinse the probe in distilled water and gently dry with a clean tissue. Short press /MEAS to turn on the tester.

2.Long press CAL/ to enter calibration mode; short press /MEAS to exit.

3.Dip the probe into 1413 µS/cm calibration solution. Stir gently, leave it to stand. Wait

for the measurement stability icon () to appear and stay on the display (see Fig 1); then short press CAL/ to complete the 1st calibration. Tester returns to measurement mode, and calibration icon “M” appears on bottom left side of display.

4.Rinse probe in distilled water and dry it. Repeat steps #2 and #3 to complete 2nd calibration in 12.88 mS/cm calibration solution. Tester returns to measurement mode, and calibration icons “M” and “H” will appear on bottom left side of display.

Measurement

1.Short press /MEAS to turn on the tester. Rinse probe in distilled water and dry it gently with a clean tissue to remove excess water.

2.Stir the probe in the sample solution gently, leave it to

stand. Wait for the stability icon () to remain on, then take a reading.

3.Rinse off the tester thoroughly in distilled water after each test.

Notes:

•If this is the first-time use or the tester hasn’t been used for a long time, we recommend soaking the probe in

12.88 mS/cm solution for 15 to 30 minutes to restore its sensitivity and speed up the response time.

•The tester adopts 1413 µS/cm and 12.88 mS/cm standard calibration solutions. User can use 1 and 2 point calibrations as needed. For most circumstances, calibrating in 1413 µS/cm to complete the 1st point calibration will meet testing requirements.

•The tester has already been calibrated after manufacture. User can use the tester immediately or can test it in the calibration solutions to test its accuracy. If error is large, calibrate the tester before using.

•We recommend replacing the calibration solution after 5 to 10 calibrations to maintain accuracy.

Setting the Parameters

When tester is off, long press /MEAS to enter setup mode. Short press /MEAS to switch from P1 to P2 to P3. Short press CAL/ and parameter will flash, then short press

/MEAS to choose desired parameter. Short press

CAL/ to confirm parameter selection. Long press /MEAS to return to measurement mode.

*Aut = all ranges (0 to 199.9 µS/cm, 20 to 1999 µS/cm, 2.0 to 20.0 mS/cm)

Notes:

•Once the readings are greater than 2000 µS/cm, the unit will automatically become mS/cm.

•Select “Yes” for P3 to restore the calibration to the theoretical values and parameter setting to original values. When tester’s calibration or measurement performs abnormally, this function can be adopted so the tester returns to factory default setting and then users can conduct calibration or take measurements again.

Battery Installation

The tester uses four AAA batteries. Please install batteries according to the following steps. Note the correct direction of battery installation: the positive side (+) of every single battery must face up. Incorrect installation of batteries will cause damage to the tester and create a potential hazard.

1.Pull the battery cap up.

2.Slide the battery cap along the direction of arrow.

3.Open the battery cap.

4.Insert the batteries (ALL POSITIVE SIDES FACING UP).

5.Close the battery cap.

6.Slide and lock the battery cap along the direction of arrow.

7.Fit the tester’s cap while making sure to push all the way down. The tester’s waterproof design may be compromised if the cap is not fitted correctly.
