Operating Instructions Before use, soak the glass bulb in distilled water for a minimum of 1 hour Power ON/OFF Turn the meter on or off by pressing the Power button. Selecting the Temperature Unit of Measure When the meter is first powered ON, the default scale setting is set to Celsius (°C). Follow the steps below to toggle between temperature units of measure. 1. Press and hold the HOLD button while powering on the meter. 2. Release the HOLD button when °C appears on the display. 3.
Auto Power Off To preserve battery life, the meter is programmed to turn off after approximately 10 minutes of inactivity. pH Calibration Procedure If the pH meter is stored for an extended period of time, prior to calibration, condition your electrode in pH 4 buffer solution or distilled water for a minimum of 1 hour. The electrode is now ready for calibration. 1. Prepare buffer solutions for calibration. It is recommended to start with calibration buffer pH 7.00 pH, followed by either pH 4.00 or pH 10.
. When completed, the pH meter will display "End" for several seconds and will then resume normal operation. 9. Repeat steps 3 through 8 for the pH 4.00 and pH 10.00 buffer solutions. Note: Always rinse the electrode with distilled water to remove any residual buffer solution before next calibration. Replacing the Electrode pH Electrodes have a finite lifespan due to inherent properties and is dependent on frequency of use and care.
