Replacing The Batteries; Warranty - AquaMaster Tools pH Temp meter P50 Pro Benutzerhandbuch

Warning
• Always make sure that there are no air bubbles present in the solution
during calibration. This could affect the measurements.
• Make sure the calibration solution is 25°C 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 (Reverse Osmosis), distilled or de-ionised
water. Pure water alters the chemistry of the reference liquid so that it
no longer works.
• DO NOT place a cold electrode in hot liquid (or vice versa). Sudden
changes 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 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
