"CAL" will now begin to blink indicating the calibration process has begun. Note: If "Err" is displayed after holding the CAL button, make sure a valid pH buffer solution is being used, and that the electrode is not dried out. The pH meter will then automatically identify the buffer solution and the current temperature. continued... REED Instruments 1-877-849-2127 | info@reedinstruments.com | www.reedinstruments.com... -
Page 8: Replacing The Electrode
If you can no longer calibrate the electrode, it is time to replace it. Follow the steps below to replace the electrode: Remove the electrode protective cap. Unscrew the electrode collar clockwise, and remove it completely. Pull the pH electrode module out. Carefully plug a new electrode module (R3500-ELECTRODE) into the socket. Tighten the electrode collar to ensure a good seal and replace the cap. Battery Replacement When the low battery icon appears on the LCD, the batteries must be replaced. -

Page 10: Product Care
• Always rinse the pH electrode in de-ionized water or rinse solution before next us. • Never touch or rub the glass bulb. • Make sure the electrode is clean. Between measurements, rinse the electrode with de-ionized water. If the electrode has been exposed to a solvent immiscible with water, clean it with a solvent miscible with water e.g. ethanol or acetone and rinse carefully with water. • Store the electrode carefully using storage solution (If not available use pH4 solution).
