Please wait approximately ten seconds while the NERO mAx prepares to take an exposure. If the NERO
mAx detects a fault condition such as a high offset, an error message is displayed and the user must
correct the error to continue (see Section 4.3--Error Messages--for more information).

After the exposure ends, the measured exposure is displayed. If an overrange occurs, an error message
will be displayed (see Section 4.3--Error Messages--for more information). In the integrate mode, the
8000 auto-resets after an exposure while retaining the measured exposure data on screen. The NERO
mAx beeps when auto reset is complete and the NERO mAx is ready for another exposure. This auto-
reset feature is not present in the rate mode. Press the RESET softkey (4) to zero the display in the rate
and integrate modes or press the mode key to exit.
Do not press the RESET softkey when the beam
is on. Inaccurate readings will result.
As a power saving feature, the NERO mAx’s display backlight turns off after one minute of no activity.
The backlight turns back on when any button is pressed or an exposure is made. In addition, after five
minutes of no activity, the NERO mAx exits from any measurement mode and returns to the mode
selection screen.
