NERO mAx won’t turn on
If the NERO mAx will not turn on, it may have a dead battery. If the battery is discharged below a safe
operating level, but not completely discharged, the red battery low LED will illuminate and the NERO mAx
will not function. When the battery is completely discharged, nothing will happen when the power switch
is turned on. The solution for both these problems is to plug in the AC adapter. The NERO mAx will
function properly with a discharged battery when the AC adapter is used. See Section 1.4--Battery
Operation and Charging.
If the NERO mAx does not turn on with the AC adapter, the adapter may be defective or the NERO mAx
is in need of repair. Please contact Fluke Biomedical at 440.248.9300.
NERO mAx battery does not appear to hold a charge
The NERO mAx rechargeable battery holds sufficient charge for up to 4 hours of operation depending
upon use. 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.
If the battery does not appear to hold sufficient charge, verify that the battery is being charged. With the
NERO mAx turned off, plug the AC adapter into the NERO mAx and plug it into a suitable power outlet.
The green battery charge indicator on the front panel of the NERO mAx should illuminate when the
battery is charging. If the green battery charge LED does not light, the battery is not charging and repairs
are needed. Please contact Fluke Biomedical at 440.248.9300 for assistance.
For more information regarding battery operation, see Section 1.4--Battery Operation and Charging.
NERO mAx will not print
Make sure that the NERO mAx printing has been enabled by going to the Setup mode and verifying that
printing has been turned on. If printing has been enabled, make sure that the printer is properly
connected to the NERO mAx, is turned on and is on-line. Also make sure that the printer has sufficient
paper. If the printer has a self-test mode, it may be useful to run its self-test to verify that the printer is
functional. For additional assistance please contact Fluke Biomedical at 440.248.9300.
For more information about printing, see Section 1.5--Printing.
NERO mAx will not communicate with NERO mAx Excel Add-In
The NERO mAx will not communicate properly with the Excel Add-in if the Add-in is started while the
NERO mAx is in a measurement mode. Under these conditions, the NERO mAx Excel Add-In ignores all
data until a mode command is sent from the NERO mAx. To remedy this situation, exit from the
measurement mode by pressing the MODE button then re-enter the measurement mode by pressing the
ENTER key.
Make sure that the RS-232 cable is connected properly between the RS-232 connector on NERO mAx
and the RS-232 connector on the computer. Also verify that the cable is a “straight” modem cable and
not a null modem cable.
