1. Rinse the electrode in de-ionized water and prepare electrode for
calibration.
2. Dip the probe into the calibration standard. Immerse the probe tip beyond
the upper steel band. Stir the probe gently to create a homogeneous
sample. Allow time for the reading to stabilize.
3. Press CAL (F2) to go to calibration mode. The screen shows conductivity
reading. The meter scans through all the available points for the selected
solution group until it finds a close match within its acceptable calibration
window. Once a match is found, the display shows ‘Stable‘ indicator.
4. Press ENTER key to confirm the calibration.
5. Rinse the probe with de-ionized water. Place it in the next solution and
follow the steps 2, 3 and 4 to calibrate other points.
Function Keys available in Conductivity Calibration mode:
TEMP (F1)
Goes to temperature calibration
CLR-C (F2)
Clears previous calibration (if any) after ENTER key is pressed for the
confirmation screen
NEXT (F3)
Shows calibration report
ESC (F4)
Exits from calibration and goes back to conductivity measurement mode
ENTER
Confirms the calibration
Not functional
6. Press ESC (F4) to go to measurement mode.
Note: If the user has selected ‘SINGLE’ point calibration and ‘AUTO’
calibration mode, the meter will go to measurement mode after step 4.
Note: If you wish to completely re-calibrate the meter, you need to clear
previous calibration data. Press CLR-C (F2) key to clear previous
calibration. The meter shows you confirmation screen. Press ENTER key
to confirm deleting previous calibration.
