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 ºC when calibrating the meter.
Failure to do so may affect the result of the calibration.
• Never store the electrode in distilled water.
• DO NOT immerse the electrode in oil, proteins or suspended solids that
leave a layer on the glass bulb.
• DO NOT soak or rinse in RO
Pure water alters the chemistry of the reference liquid so that it no longer
works.
• DO NOT place a cold electrode in hot liquid
in temperature may break the glass and permanently damage the pen.
Broken glass is not covered by the warranty.
• Make sure not to bump the glass electrode into anything, because this
might break the glass bulb on the outside of the internal glass tube.
Broken glass is not covered by the warranty.
• Avoid placing the meter near ballasts or any other electrical appliances.
Force fields may affect the readings.
• If during calibration the pH/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.
