Page 6: Operating Instructions
This can be attained using manual or automatic temperature compensation. The electrode included with the R3525 automatically compensates for solution temperature changes with the electrode's built-in thermometer. The temperature compensation is active when the solution temperature deviates from room temperature. -
Page 7: Ph Measurement Mode (Automatic Temperature Compensation)
pH Measurement Mode (Automatic Temperature Compensation) Note: Electrodes should always be rinsed before and between samples with distilled or DI (de-ionized) water to remove all traces of previous test solution or storage solution. Connect the included pH Electrode into the Input (BNC) Jack and temperature input jack. -
Page 8: Mv Output Measurement Mode (Ph Electrode)
The LCD will display the pH electrode output in mV. ORP Measurement Mode (Optional R3525-ELECTRODE2 required) Connect the ORP Electrode into the Input (BNC) Jack. Press the button to select mV (ORP) mode. - Page 9 Prepare buffer solutions for calibration. It is recommended to start with pH 7.00 buffer solution, followed by either pH 4.00 or pH 10.00 (whichever is nearest to the expected sample value). Use the pH 4.00 and pH 7.00 buffer solutions when measurements are expected to be on the lower side of the pH scale.

Page 10: Orp Calibration
ORP Calibration (Optional R3525-ELECTRODE2 ORP Electrode required) Calibration is not required for ORP mode, however, you can spot check ORP measurements with the use of a specific ORP standard solution to ensure the electrode is still within specifications. Battery Replacement When the low battery icon appears on the LCD, the battery must be replaced. -
