EC, TDS, PPM calibration
Watch the How-to videos at Aqua Master Tools' website.
1. Make sure the EC electrode is connected.
2. Turn on the meter by pressing the On/Off button.
3. Press the MODE button to switch to EC mode on the display.
4. Gently clean the electrode with distilled water and dry it off.
5. Insert the EC electrode in calibration solution (uS/cm 1413) mS/cm
1,41 EC (make sure this is 25°C) and stir gently.
6. Allow the reading to stabilise.
7. Press and hold the EC CAL button for 5 seconds until the value of
the calibration 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.
8. After a successful EC calibration, the CAL logo (calibration reminder
indicator) will appear at the bottom right of the screen.
9. Rinse the electrode with tap water and dry it.
Calibration indicator
The calibration indicator will appear after successfully calibrating pH
or EC. The indicator will disappear after 30 days as a reminder that the
device needs to be recalibrated.
When is calibration required
• If the electrode has been replaced.
• If the meter was last calibrated over a month ago.
• If the meter is used on a regular basis.
• If high precision is needed.
Replacing the battery
The battery need to be replaced according to the battery indicator.
Or if the meter no longer turns on then replace the 9 Volt battery.
