INTRODUCTION

Congratulations for buying one of the most innovative and easy to use Pocket Tester.

Pocket testers series 1 and 5 are very handy for the routine measurements in all applications where

fast indication of measurement is required.

These Testers are specially designed for applications like: Agriculture, water and waste water

treatment, Hydroponics, Aquaculture, Environmental monitoring, Food and beverage

manufacturing, Cooling towers, Printing, Education etc.

Tester series 1 is basic one with fixed sensor and only two keys for all functions.

Tester series 5 is advanced version with replaceable sensor, multicolour backlight display and 3 key

for all functions.

SAFETY INSTRUCTIONS

Read this instruction manual carefully before using your new tester.

The membrane of pH electrode is made of glass and can be danger in case it breaks.

To avoid damage check the electrode tip after each measurements.

Replace all batteries together with the same type.

The manufacturer of these instruments can’t be held responsible for any improper use.

Verification of the measuring results is the responsibility of the operator and the manufacturer

doesn’t respond to any direct of indirect damage occurred while using this instrument.

DISPOSAL OF ELECTRONIC DEVICES

The electrical and electronic equipment marked with this symbol cannot be

disposed of in public landfills.

According to the UE Directive 2002/96/EC, the European users of electrical

and electronic equipment can return it to the dealer or manufacturer upon

purchase of a new one.

INSTRUCTIONS FOR PH2620-pH1 / EC2620-Cond1

POWER ON

Press key once, the meter will switch ON and the display will show all the segmetns active for 2

sec. and then i twill display the following:

All segments ON -> model name + software release -> measurement

POWER OFF

To turn off the meter press key for 3 seconds, the meter will switch OFF.

SETUP MENU for PH2620-pH1 / EC2620-Cond1

1. With meter switched off, press and hold CAL key and press key once.

2. The meter will switch on wit hall the segements active, release CAL key, the meter

will go into the Setup Menu.

3. The display will show SLT on primary display with COND flashing (only for EC2620-

Cond1).

4. Press to select the parameter between COND or TDS to be used for

measurements and press to confirm (only for EC2620-Cond1).

o Only if the TDS is selected then the display will show TDS, FCT flashing, press

to change this factor and then press to confirm (only for EC2620-Cond1).

5. The display will show RST (RESET): nO flashing.

6. Press and select YES if a reset of the meter is required and then press

to confirm.

7. At this point the meter finishes SETUP menu and switches off.

NOTE: To skip the changing of the value simply confirm the flashing value with

key, the meter will go tot he next Parameter.

METING

Rinse the electrode with distilled water or sample prior to start measurement.

Fill the measuring cap with sample, switch on the meter with , immerse the Tester in

sample and wait for stability, when stability icon ☺appears on display take the reading.

During measurement make sure that pH electrode membrane is free from air bubbles,

and that there isn’t any air bubble around or between conductivity sensor.

CALIBRATION PROCEDURE FOR CONDUCTIVITY (EC2620-Cond1)

1. Power ON the meter by pressing the key.

2. Rinse the probe with distilled water.

3. Immerse the probe in the calibration solution (1413µS or 12.88 mS), wait for stability ☺

4. Press CAL key.

5. The meter will start calibration procedure and will recognise automatically the

standard used.

6. When stable press to confirm and complete the calibration.

7. The standard value will flash for 3 times and then the meter will go into the

measurement mode.

8. If the 2nd point calibration is required then rinse the probe with distilled water and

immerse in the second standard solution (1413µS or 12.88 mS), wait for stability ☺

9. Repeat the points 4 to 7.

10. The calibration process is completed and the meter is ready to use.

NOTE: Anytime press key to abort and exit from calibration procedure.

Reading based on theoretical cell value C=1

Standard solution

CALIBRATION PROCEDURE FOR TDS (EC2620-Cond1)

When the meter is set to read TDS then the calibration is done on TDS with 1 or 2 points.

The calibration procedure for TDS is same as for Conductivity.

CALIBRATION PROCEDURE FOR pH (PH2620-pH1)

1. Power ON the meter by pressing the key.

2. Rinse the electrode with distilled water.

3. Immerse the electrode in the 1st buffer solution pH7.0 and wait for stability ☺

4. Press CAL key.

5. The meter will start calibration procedure and will recognize automatically the

standard used.

6. When stable press to confirm and complete the calibration.

7. The standard value will flash for 3 times and then the meter will ask for next point

for calibration. If only 1 point calibration is required then press to finish and exit.

8. If the 2nd point calibration is required then rinse the electrode with distilled water

and immerse in pH4.0 or pH10.0, wait for stability ☺

9. Repeat the points 4 to 7.

10. The calibration process is completed and the meter is ready to use.

NOTE: Anytime press key to abort and exit from calibration procedure.

NOTE (2): When the first point calibration is confirmed (point 7) if the sensor is not

removed from the buffer solution, the instrument may give wrong buffer error.

1. Power ON the meter by pressing the key.

2. Rinse the probe with distilled water.

3. Immerse the probe in the calibration solution (84μs, 1413μS or 12.88 mS), wait for

stability ☺

4. Press CAL key, (blue backlight during calibration).

5. The meter will start calibration procedure and will recognise automatically the

standard used.

6. When stable press to confirm and complete the calibration.

7. The standard value will flash for 3 times and then the meter will go into the

measurement mode.

8. If the 2nd point calibration is required then rinse the electrode with distilled water

and immerse in the 2nd Standard, wait for stability ☺

9. Repeat the points 4 to 7.

10. If the 3rd point calibration is required then rinse the electrode with distilled water

and immerse in the 3rd Standard, wait for stability ☺

11. Repeat the points 4 to 7.

12. The calibration process is completed and the meter is ready to use.

NOTE: Anytime press ESC key to abort and exit from calibration procedure.

NOTE(2): In case multipoint calibration is performed it is better to start from the lower value

standard first and then go increasing.

CALIBRATION PROCEDURE FOR pH (PH2630-pH5, EP2000-PC5)

1. Power ON the meter by pressing the key.

2. Rinse the electrode with distilled water.

3. Immerse the electrode in the 1st buffer solution pH7.00 and wait for stability ☺

4. Press CAL key (blue backlight during calibration).

5. The meter will start calibration procedure and will recognize automatically the

standard used.

6. When stable ☺press to confirm and complete the calibration.

7. The standard value will flash for 3 times and then the meter will ask for next point

for calibration. If only 1 point calibration is required then press to finish and exit.
