To calibrate the Apera EC700 Benchtop Conductivity Meter, follow these steps:
1. Rinse the electrode in distilled or pure water, allow it to dry, and wash it with a little of the standard calibration solution.
2. Submerge the electrode in the standard calibration solution and stir the solution briefly.
3. Wait until a stable reading is reached.
4. Press the key to enter the calibration mode. The "CAL" icon will flash at the top right of the LCD display.
5. The meter will start scanning and locking onto the calibration solution. When it locks onto the solution, a stable icon will appear on the LCD display.
6. Press the key to complete the calibration. The "End" icon will show up, and the meter will return to the measuring mode.
Note: It is important to wait until the reading is stable before pressing the key to complete the calibration. If the reading is not stable, the "Err4" self-diagnosis icon will appear.
For multi-point calibration, repeat the above steps with different calibration solutions. The meter can repeat calibration in the same solution until a stable value is reached.
Please refer to the Apera EC700 Benchtop Conductivity Meter Instruction Manual for more detailed instructions and information on calibration.
