vPad-XSC for Impulse 4000 USER MANUALThe 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,unitsFor 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); andunits 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 vPLstatement that executes the pacer pulse test itself.3.2.1.4 Example 4: Disabling a LimitSometimes automatic assessment may not be desirable, in which case a vPL statement similar tothe following can be used to disable a particular limit. For example:xctrl “Disabling pulse width limit" | lim6,noneFor 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 commandare omitted because they are not necessary.Once a limit has been disabled, a target specified in a “xtest” statement will appear in the TestRecord, but the corresponding measurement value will not be passed or failed automatically.Operation/Chapter 3 # Page 9
