Operation and use
- Remove the protective cover.
- Gently clean the electrode with distilled water and dry it off.
- Press the On/off button to start the meter.
- Insert the meter upright into the solution up to the edge and stir gently. Wait a few seconds for the correct value to appear on the display.
- Press the C/F button to switch between Celsius and Fahrenheit.
- Rinse the electrode with water after use and press the On/off button to turn off the meter.
Calibrating the EC meter
- Press the On/off button to start the meter.
- Gently clean the electrode with distilled water and dry it off.
- Insert the meter in an upright position in calibration solution (μS/cm 1413) EC 1.41 (make sure this is 25°C) and stir gently.
- Wait until the value on the display is stable.
- Press and hold the CAL button for 5 seconds. Then release the button. The value EC 1.4 will now blink on the display. As soon as the meter switches back to the standard mode, calibration is complete.
- Rinse the meter with clean water.
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 electrode
- Properly unscrew the sealing ring in the lower part of the meter.
- Remove the defected/old electrode by gently pulling it.
- Carefully place the new electrode with the recess in the correct position so that the connectors properly connect and do not damage the meter or electrode.
- Check that the rubber seal is properly placed.
- Tightly tighten the sealing ring.
- Calibrate the meter as described in this manual.
- The meter is now ready for use.

Warning
- Always make sure that there are no air bubbles present in the solution during calibration. This could affect the measurements.
- If the EC value does not decrease to 0, insert the electrode into ethyl alcohol and shake gently for 5 to 10 seconds.
- Make sure the calibration solution is 25°C when calibrating the meter. Failure to do so may affect the result of the calibration.
- Avoid placing the meter near ballasts or any other electrical appliances. Force fields may affect the readings.
- If during calibration the EC value keeps rising or dropping slowly and does not stabilise, please replace the batteries and calibrate the meter. Bad batteries or low power levels may influence the measurement results.
Replacing the batteries
If the battery indicator at the top right of the display is activated, or if the display dims, please replace the batteries. To do so, unscrew the top and replace the 3 x 1.5 Volt AG-13 button cell batteries.
