MEASUREMENT
Rinse the electrode with distilled water or sample prior to start measurement.
Fill the measuring cap with sample, switch on the meter with and press
MODE key to select
desired parameter to be measured (green backlight during measurement).
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 is free from air bubbles, and that there isn’t
any air bubble around or between conductivity sensor.
CALIBRATION PROCEDURE FOR CONDUCTIVITY (EC2630-Cond5/EP2000-PC5)
1. Power ON the meter by pressing the key.
2. Rinse the probe with distilled water.
3. Immerse the probe in the calibration solution (84
μ
s, 1413
μ
S 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 2
nd
point calibration is required then rinse the electrode with distilled water
and immerse in the 2
nd
Standard, wait for stability
☺
9. Repeat the points 4 to 7.
10. If the 3
rd
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 1
st
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.
