Power Control

A pushbutton power switch is located on the back panel of the instrument. Power is
applied to the AccuPulse Handheld device by plugging the power cord into the back of
the unit, and the power supply into an outlet. While plugged in the batteries will charge,
whether the instrument is on or off.

Device Power Up

There is a 3 second delay upon powering up before information appears on the display.
The AccuPulse Handheld initially shows a splash-screen indicating the device type, its
serial number and the version number.

Fig.S1

From this screen, the user can see the model, Serial Number and software version of the
device. After a few seconds, the splash screen is replaced by the 

BP Test

mode screen

(NIBP Keypad), or the main menu (Generic Keypad). 

When a customer later purchases an upgrade to the software or there is a software fix,
it can be installed in the field. This will be done through an update utility provided by
Clinical Dynamics as required.

Freeze the Splash Screen:

If the user needs to record key information, such as the software version they have, the
splash screen can be frozen. Immediately after the splash screen is displayed, press 2
keys simultaneously, then let go of them. This will freeze the splash screen until any new
key is pressed.

Device Modes

There are four main modes to the AccuPulse Handheld PLUS product. These are:

•BP Test: 

Tests the accuracy and precision of an attached blood pressure monitor.

• Supports 7 Adult and 6 Neonatal presets.
• Autosequence
• User adjustment of most parameters in 

BPTest

mode.

• Optional CalTables provide presets adjusted to suit specific common equipment.
• Optional User-Defined module adds expanded user control of parameters for power users
• Optional Motion artifact to simulate operation of the device in harsh environments

such as inside a helicopter or ambulance.

• Optional Arrhythmia function.

• Leak Test:

Tests for leaks in the BP Monitor system.

• A built-in pump supports automated Leak Test.
• Users can configure and store 3 automated settings of differing pressures and

duration.

• OverP Test:

Finds the pressure at which the overpressure valve of an NIBP monitor

opens.

• A built-in pump supports automated OverP Test.

• Meter:

Measure pressure in the system in tenths of mmHg

• In addition to the current reading, displays Min., Max., and a moving Average.
• Set Meter Units ( mmHg, kPa, cmH20, psi ).
• The built-in pump supports automated inflation in steps of 50mmHg.
• The built-in pump supports automated inflation to user defined set point (adjustable

on the fly).

When selecting another mode, results displayed on various screens are maintained so
that a user may run a test in one mode, and come back to a previous mode to see the
last data collected in that mode.

NOTE: The unit may automatically zero itself at 1 minute intervals so that any drift is
removed. There will be a slight audible click heard when this occurs.

Front Panel Buttons

There is a variation in front panel labels between single function NIBP units and future
variations with multiple parameters. Dedicated mode buttons were used originally, while
newer releases support further expansion through the use of a generic set of keys. The
overall operation of the unit is consistent between versions except that in the newest
version the mode buttons have become menu selections on the screen.

Mode Buttons 

(units with only NIBP)

Pressing any of the front-panel mode buttons 

<BP Test> , <Leak Test> , <OverP

Test> or <Meter>

causes the AccuPulse Handheld to change to the indicated mode.

The exceptions are when there is pressure in the system above a given threshold. Each
mode has a trigger pressure past which the user cannot leave the mode. For instance,
when in BP Test Mode, the AccuPulse Handheld will generate pulses automatically when
Press > 10mmHg. The AccuPulse Handheld will not change modes until the pressure
in the system is < 10mmHg for that reason.

Menu Selection Buttons 

(Generic Keypad)

The front-panel buttons 

<Scroll Up>

and 

<Scroll Down>

move the highlight up

and down the menu list, 

<ENTER>

selects the currently highlighted selection.

Pressing 

<ESCAPE>

will back out of the current menu or mode, moving up the menu

tree to the next level. The exceptions are when there is pressure in the system above a
given threshold. Each mode has a trigger pressure past which the user cannot leave the
mode. For instance, when in BP Test Mode, the AccuPulse Handheld will generate pulses
automatically when Press > 10mmHg. The AccuPulse Handheld will not change modes
until the pressure in the system is < 10mmHg for that reason.
