1.4 Battery Operation and Charging
The NERO mAx has an internal rechargeable battery which provides up to four hours of continuous
operation depending upon usage. The NERO mAx draws twice as much power from its from its battery
when it is actively making measurements than it does when in an idle state with its backlight off. To
conserve and extend battery life, the NERO mAx incorporates several power saving features. The
display backlight automatically turns off after one minute of inactivity. The backlight turns on when any
key is pressed or an exposure is made while in any measurement mode. In addition, the NERO mAx
exits from any measurement mode after five minutes of no activity. Pressing the ENTER key restores the
NERO mAx to its previous measurement mode.
The NERO mAx utilizes two levels of protection to assure reliable operation when the battery charge
becomes low. The first level of protection is a warning that is displayed when there is approximately 20
minutes of battery life remaining. During this time, the AC adapter may be plugged into the NERO mAx to
continue operation without interruption. The second level occurs when the battery charge is insufficient to
guarantee proper operation. When this occurs, the low battery indicator in the lower left corner of the
front panel illuminates and the instrument shuts down, becoming inoperable. When this happens, the AC
adapter can be plugged into the NERO mAx to restore operation. The NERO mAx “remembers” what
mode it was in before it shut down and returns to that mode upon power up. Pressing the ENTER key
returns the NERO mAx to its measurement mode.
The battery is charged whenever the NERO mAx is connected to its AC adapter and the adapter is
plugged into a suitable power source. When the power switch is on, the battery is charged at a low rate
that is enough to sustain the battery’s charge. When the power switch is off, the battery is charged at a
high rate.
To fully charge the battery, make sure that the NERO mAx is turned OFF, plug the AC adapter into the
rear of the NERO mAx console and plug the adapter into a suitable power source. The green battery
