vPad-XSC for Impulse 4000 USER MANUAL
The following vPL statement sets pacer pulse current limit to a target with tolerance in mA:
xctrl “Setting pulse current tol. to +/-3mA" | lim4,target,3,units
For this statement,
4
immediately following the “
lim
” command specifies the limit is for pacer current;
target
specifies the limit type as a target with tolerance, as opposed to a min/max range;
3
is the tolerance value (±3); and
units
sets the tolerance type as a number of milliamps as opposed to
% (percent)
.
The "target" value referred to above is not included with the limit, but is specified in the vPL
statement that executes the pacer pulse test itself.
3.2.1.4 Example 4: Disabling a Limit
Sometimes automatic assessment may not be desirable, in which case a vPL statement similar to
the following can be used to disable a particular limit. For example:
xctrl “Disabling pulse width limit" | lim6,none
For this statement,
6
immediately following the
"lim"
command specifies the limit is for pacer pulse width;
none
sets the limit to
"none"
, disabling automatic pass/fail. Other parameters of the command
are omitted because they are not necessary.
Once a limit has been disabled, a target specified in a
“xtest”
statement will appear in the Test
Record, but the corresponding measurement value will not be passed or failed automatically.
