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 ( 
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
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 (
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 calibra-
tions 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 manufac-
ture. User can use the tester immediately or can test it in
the calibration solutions to test its accuracy. If error is

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
to return to measurement mode.

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.
