USB Memory Status Icons
When you insert a USB drive into the 831Cs USB port, the USB drive icon
appears in the Status bar of the meter's display as shown in Figure 2-6.
If the Data Storage setting is set to USB, but no USB drive is inserted, the USB
not available icon appears. Files save to the meter until you insert a USB
drive.
If the USB drive is removed during a measurement, the same icon appears,
the measurement ends, and data with that measurement is not visible on the
meter. When the USB drive is reinserted, the USB caution icon appears. The
meter notifies you that there is unsaved data and prompts you to Save or
Delete the measurement data. You cannot continue with the same
measurement.
Input Overload Icon
When a signal from the preamplifier exceeds the calibrated input range of the
831C, the Input Overload icon appears. While the overload is present, the icon
flashes.
When the overload condition resolves, the icon is still present (not flashing) to
indicate that an overload has occurred during the measurement. Press the
RESET button to clear the icon from the display.
Under Range Icon
The Under Range icon displays in the status bar while an under range
condition applies. For details about the under range level, see 5.1.2
