- The meter will automatically recognize the standard solution and automatic calibration. During this process, calibration value will be shown on the Second Display.
- After Calibration, meter automatically returns to Measurement Mode.
At most 2 points calibration: 0% and 100%, when the solution cannot be recognized, show "Err" for 2s. Then automatically returns to Measurement Mode.
