EC1 Pocket Conductivity Tester Instruction Manual
1. Battery Installation
Please install batteries according to the following steps. *Please note the correct
direction of battery installation:
The Positive Side (“+”) OF EVERY SINGLE Battery MUST FACE UP.
(WRONG INSTALLATION OF BATTERIES WILL CAUSE DAMAGE TO THE
TESTER AND POTENTIAL HAZARDS!)
2. Keypad Functions
■Short press------- < 2 seconds
■Long press-------- > 2 seconds
1. Short press to turn on, long press to turn off;
2. When turned off, long press to enter setup;
3. In mode setting, short press to change
parameter;
1. When turned on, long press to enter
calibration mode.
2. In calibration mode, short press to confirm
calibration;
3. In mode setting, short press to confirm
parameter selection.

3. Calibration
3.1 Rinse the probe in distilled water and dry it with a clean
tissue. Short press to turn on the tester.
3.2 Long press to enter calibration mode; Short press
to exit.
3.3 Dip the probe into 1413 µS/cm calibration solution. Stir gently, leave it to
stand, LCD displays (Diagram 3), short press to complete 1-point
calibration. The tester returns to measuring mode, and calibration icon
appears at the bottom left of LCD.
3.4 Rinse probe in distilled water and dry it. Follow the steps in 4.2-4.3 to
complete 2nd point calibration in 12.88 mS/cm calibration solution, tester returns
to measurement mode, calibration icons display on bottom left of LCD.
4. Conductivity Measurement
4.1 Short press to turn on tester. Rinse probe in distilled water and dry it
with a clean tissue to remove excess water.
4.2 Stir the probe in the sample solution gently, leave it to stand. Get readings
after the smile icon comes up and stays.
4.3 Rinse off the tester thoroughly in distilled water after each test.
5. Notes
5.1 If it’s 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 15-30 minutes to
restore its sensitivity and speed up the response time.

5.2 The tester adopts 1413 µS and 12.88 mS standard calibration solutions. Users
can use 1-2 point calibrations as needed. For most circumstances, calibrating in
1413 µS to complete 1st point calibration will meet testing requirements.
5.3 Unit Information: 1 mS/cm = 1000 µS/cm
Once the readings are greater than 2000µS/cm, the unit will automatically
become mS/cm.
5.3 The tester has self-diagnosis functions:

which exceeds the
recognizable range of the
meter.
1. Check if calibration solution is
correct
2. Check if probe isdamaged.

measurement is stable
( comes up and stays)
Wait for the smile icon to stay,
and then short press
5.4 The tester has already been calibrated after manufacture. Usually users can
use the tester right away, or test it in the calibration solutions to test its
accuracy. When error is large, calibrate it before using.

6.2 How to setup parameters:
When turned off, long press to enter setup →short press to switch
P1-P2→Short press , parameter flickering→short press to choose,
short press to confirm parameter selection→Long press to switch off.
6.3 Parameter setting notes
a) Select conductivity ranges (P1):
Aut-- All ranges: 0 –199.9 µS/cm, 20 –1999 µS/cm, 2.0 –20.0 mS/cm;
Factory default is Aut.
b) Restore to factory default:
Select Yes to restore the calibration to the theoretical values and parameter
setting to original values. When meter’s calibration or measurement performs
abnormally, this function can be adopted so the meter goes back to factory
default setting and then users can conduct calibration or take measurements
again.
