General settings

4. Select "AS" to set the auto stability, or select "AH" to set the auto hold. And

then press the

key to confirm selection.

To return to the measurement mode, press the

key.

Note

In the calibration mode, the auto stability mode always works.

Tip

The stability judgment criteria are the same for both the auto stability mode and auto hold
mode.
