5. Connect a reference pressure gauge and pressure
source in parallel with the BpTRU cuff connector to
form a closed system.
6. Press BP Start to close the BpTRU’s valve. This closes
the pneumatic system and allows pressure to be
applied to the BpTRU pressure transducer.
The maximum time for the valve to remain closed is
approximately 3 minutes. After this time, the valve is
opened and the Pulse display shows “ccc.” When the
valve has cooled, the pressure display will re-illuminate.
7. Apply a static pressure of up to 300 mmHg, and
compare the pressure displayed in the BpTRU Pulse
and Reading displays to the reference pressure gauge
to verify accuracy.
A properly calibrated monitor should read within 3
mmHg of the reference pressure gauge at all pressures.
8. Apply static pressure greater than 330 mmHg, or
pressure greater than 10 mmHg for 3 minutes, to
check if overpressure or over inflation time safety
mechanisms are operating properly and error codes
are displayed. Remove the fault condition and press
BP Clear to remove the error code. Note that the valve
will remain open for 30 seconds following activation
of a safety mechanism.
9. Press Stop to open the valve.
10.Return to normal operation by turning the BpTRU off
and then on again using the power switch.
Temperature Alert/Silent Mode (BPM300)
The BpTRU makes a short audible tone after completing
a single temperature measurement. This feature is
enabled by default, but can be disabled and reenabled as
follows.
1. Turn the BpTRU off using the power switch.
2. To toggle BP Alert/Silent mode, hold the Temperature
Start button while turning the BpTRU on again.
Repeating this toggles the BpTRU to the previous state.
