3.4.8 Automatic Shutdown

Choose Automatic Shutdown Status from the Configuration menu to activate the Automatic Shutdown feature.

If you select Enable, the instrument switches off automatically after 10 minutes of inactivity, thereby economizing battery power.

3.4.9 Measurement Mode

Choose Measurement Mode from the Configuration menu to enable maximum measurement mode for sampling in bottles and cans.

In Maximum measurement mode, the instrument searches for two consecutive measurements with less than a 2% difference, as also described in “Measurement Mode” on page 19.

When this occurs, the display is frozen and you may store the data. The instrument remains in this mode until you select Normal measurement mode.
