pH calibration
Watch the How-to videos at Aqua Master Tools' website.
1. Ensure that the pH electrode is connected to the handheld meter.
2. Turn on the meter by pressing the On/Off button.
3. Press the MODE button to switch to pH mode on the display.
4. Remove the pH electrode's protective cap.
5. Gently clean the electrode with distilled water and dry it off.
6. Insert the pH electrode in pH buffer solution pH 7.00 (make sure
this is 25°C) and stir gently.
7. Wait until the value on the display is stable.
8. Press and hold the pH CAL button for 5 seconds until the value of the
buffer solution is displayed. The meter will automatically recognise
the buffer solution and calibrate itself. As soon as the meter switches
back to the standard mode, calibration is complete.
9. Gently clean the electrode with distilled water and dry it off.
10. Insert the pH electrode in pH buffer solution pH 4.01 (make sure this
is 25°C) and stir gently.
11. Wait until the value on the display is stable.
12. Press and hold the pH CAL button for 5 seconds until the value of the
buffer solution is displayed. The meter will automatically recognise
the buffer solution and calibrate itself. As soon as the meter switches
back to the standard mode, calibration is complete.
13. After a successful 2 point calibration, the CAL logo ( calibration
reminder indicator ) will appear at the bottom right of the screen.
14. Rinse the pH electrode in tap water.
15. Fill the pH electrode's protective cap with storage solution and
replace it.
Please note that if the meter displays an error during calibration, either the
buffer solution does not have the correct value or the electrode is dirty or worn
and has to be replaced.
