vPad-XSC for Impulse 4000 USER MANUAL
3.2 Configuration
As an optional function, the Interface has the ability to automatically assign a pass/fail result for
measurement data obtained from
Impulse 4000
. Configuration statements can set limits for automatic
pass/fail assessment, as well as to change Impulse 4000 settings for defibrillator and pacemaker tests. In a
Checklist, pass/fail limits and
Impulse 4000
settings are configured with
“xctrl”
statements. For more
information on the
“xctrl”
statement, refer to the vPad-Check Operating Manual .
3.2.1 Setting Limits and Tolerances
The Interface supports the following
Impulse 4000
test functions:
• defibrillator energy
• defibrillator charge time
• defibrillator sync delay (cardioversion)
• pacer pulse
• pacer refractory period
• pacer noise immunity
• pacer sensitivity
When automatically assigning a pass or fail, each test utilizes one or more pass/fail limits which are stored
in the Interface’s memory. Limits are initialized to default values when power is applied to the Interface,
but may be modified through the
"lim" command. Modified limit settings do not persist once the
Interface is disconnected from the vPad safety analyzer, or the safety analyzer is powered off. Limits are
set as required during Checklist runtime.
Limit configuration statements in vPL are of the form
xctrl“< info >" | lim< id >,< type >,< p1 >,< p2 >
where:
< info >
is a description of the limit setting, which is briefly displayed to the user
< id >
is an ID number (1, 2, 3...) representing the limit to be set,
< type >
is the type of limit, such as a target with % tolerance or a min, max or range,
< p1 >
is the first pass/fail threshold, the effect of which depends on limit type, and
< p2 >
is a second pass/fail threshold which, again, depends on limit type.
