WP34S Reset during printing

[walter b]

IIRC, a similar problem was reported earlier this year. Since I guess you're well equipped, I'd suggest you power your WP 34S using a 3 VDC source of larger capacity (a larger battery should do) and check if the problem persists. I'll look for that previous case in the meantime.
