1.3.14 BATTERY OPERATION
When the Accutorr Plus is powered from the battery, the Battery Indicator (17) is
illuminated continuously.
To conserve power, most displays will blank (time out) at user selected times. The LCD
illumination time out can be set between 3 and 15 minutes. The LED displays time out
can be set between 5 and 60 minutes. Since the Accutorr Plus can be powered from either
an AC or DC source, the user configuration allows the setting of separate times for each
type of power source. See User Configuration, section 3.15 for more information on
setting the time out minutes.
When the battery charge is low, but not below the cutoff voltage, the battery LED will
flash and the recorder will not operate. When the LED begins to flash on Sealed lead acid
units, approximately 30 minutes of battery time remain for the Accutorr Plus NIBP, 20
minutes for the Accutorr Plus NIBP with Trend Screen and 10 minutes for the Accutorr
Plus NIBP with Trend Screen and SpO2. Units with Lithium ion batteries will provide
approximately 10 minutes of low battery warning time.
When the battery charge drops below the cutoff voltage the Accutorr Plus will
automatically turn off. Patient information will be retained for later use.
Battery run time for the Accutorr Plus NIBP is approximately 5 hours with a Sealed lead
acid battery or 8 hours with a Lithium ion battery using a new fully charged battery at
25C with a NIBP measurement taken every 5 minutes and the recorder not in use.
Battery run time for the Accutorr Plus NIBP with Trend Screen is approximately 3 hours
for a Sealed lead acid battery or 8 hours for a Lithium ion battery using a new fully
charged battery at 25C with a NIBP measurement taken every 5 minutes and the
recorder not in use. Battery run time for the Accutorr Plus NIBP with Trend Screen and
Datascope SpO2 is approximately 1.5 hours for a Sealed lead acid battery or 3.5 hours for a
Lithium ion battery using a new fully charged battery at 25C with a NIBP measurement
taken every 5 minutes continuous SpO2 measurement and the recorder not in use. Battery
run time for the Accutorr Plus NIBP with Trend Screen and Masimo or Nellcor SpO2 is
approximately 2 hours for a Sealed lead acid battery or 4.5 hours for a Lithium ion battery
using a new fully charged battery at 25C with a NIBP measurement taken every 5 minutes
continuous SpO2 measurement and the recorder not in use.
The Accutorr Plus automatically recharges the battery, when required, when the unit is
plugged into an AC receptacle. Maximum battery recharge time is 8 hours for Sealed
lead acid or 2 hours for Lithium ion.
CAUTION: To avoid loss of patient data (trend), do not replace the battery unless the
Accutorr Plus is connected to an AC receptacle. Hospital defaults and the time are
unaffected by battery replacement.
