Power requirements
The medical-rated isolation AC power adapter connected to the AC supply must supply 8
volts DC and 0.74 amperes.
Battery
The monitor uses a (supplied) sealed lead-acid, 6V, 4 Ah battery with external
recharge capability.
The battery charges to at least 90% capacity in 12 hours. The AC power adapter, when
connected, simultaneously operates the monitor and charges the battery; it charges the
battery more rapidly if it is not simultaneously operating the monitor.
Using a new, fully charged battery, the monitor can be operated continuously for at least 8
hours of Adult NIBP monitoring, at 3-minute intervals, with simultaneous and continuous
monitoring of temperature and SpO
In other words, a new, fully charged battery supports at least 165 Adult NIBP readings at
3-minute intervals while simultaneously and continuously monitoring and displaying
temperature and SpO
Leakage current
For maximum patient electrical isolation, connect a computer to the monitor only when
the monitor is not connected to a patient or when the computer is outside the patient
field running on battery power.
