OPERATION: • Do not be alarmed if white crystals appear around the cap. This is normal with pH electrodes and they dissolve if rinsed with water. pH • Remove the protective cap and turn the pHep® on. • Immerse it in the sample up to the maximum immersion level. • Stir gently and wait until the display stabilizes. • After use, rinse the electrode with water to minimize contamination. • Store the electrode with a few drops of storage (HI 70300) or pH7 (HI 7007) solution in the protective cap.
• Allow the reading to stabilize and using a small screwdriver turn the pH 7 Calibration Trimmer to read 7.0. Calibration is now complete. ALWAYS USE FRESH BUFFERS FOR CALIBRATION & NEVER REUSE THEM. BATTERY REPLACEMENT: When the pHep® cannot be switched on or the display fades, pull out the battery compartment and replace all three 1.5V batteries, paying attention to their polarity. Batteries should only be replaced in a non-hazardous area using the battery types specified in this instruction manual.
