Environmental Requirements
The evaluation board must be stored between -40°C and 100°C. The recommended operating temperature is
between 0°C and 90°C.
The evaluation board can be damaged without proper anti-static handling.

Troubleshooting
No Current/Voltage Meter Readings Available
A low battery can cause the current/voltage meter features of the Pico Power demo to read 0µA/0V. The demo’s
counter and shift register features may operate but the additional current required to energize the current sensor
and POWR6AT6 may not be available once the battery begins to discharge. Install a new battery if this condition
occurs.
Determine the Source of a Pre-Programmed Part
It is possible that you may receive your Pico board after it has been reprogrammed by someone else. To restore the
board to the factory default, see the Download Demo Designs for details on downloading and reprogramming the
device.
You can also determine which demo design is currently programmed onto the Pico board by comparing the JEDEC
checksums against of the programming file with what is read from the programmed part.
To compare JEDEC file checksum:
1.
Connect the Pico board to a host PC using the USB port.
2.
Start ispVM and choose
ispTools > Scan
. The POWR605 and POWR6AT6 devices appear in the Device List.
3.
Double-click the
device row
. The Device Information dialog appears.
