Mains power quality should be that of a typical
commercial or hospital environment. If the user
of the Welch Allyn Remote Monitoring
ScaleRPM-Scale100 requires continued
operation during power mains interruptions, it
is recommended that the Welch Allyn Remote
Monitoring Scale RPM-Scale100 be powered
from an uninterruptible power supply or a
battery.
