Warranty Disclaimer Should you elect to have your instrument serviced and/or calibrated by someone other than Datrend Systems, please be advised that the original warranty covering your product becomes void when the tamper-resistant Quality Seal is removed or broken without proper factory authorization. We strongly recommend, therefore, that you send your instrument to Datrend Systems for service and calibration, especially during the original warranty period.
In addition to automated control of operation, the vPad-XSC provides automatic Impulse 4000 assessment of measurement results based on user-defined limits This manual provides guidance for users integrating vPad-Check™ and vPad-XSC™ for Impulse 4000 into new and existing maintenance processes. 1.1 Standard Accessories...
Impulse 4000 USER MANUAL 1.3 Checklists and vPL Checklists In vPad-Check, equipment maintenance and inspection procedures are called . A Checklist can contain a sequence of prompts for the operator as well as machine instructions to configure the vPad safety analyzer and to conduct other tests through a remote instrument.
Connect the XBUS port on the Interface to the XBUS port on the vPad safety analyzer using the RJ12 cable (P/N 3140-069) provided with the Interface. Note that the two XBUS ports on the Interface are interchangeable. This enables several vPad-XSC interfaces of different types to be chained in series if necessary.
Impulse 4000 USER MANUAL 3 Checklist Programming A Checklist contains operator prompts and machine instructions for conducting an automated maintenance and inspection sequence. To create or edit a Checklist (with a .vpl extension), you may use any text editor that works with plain text (.txt) files, or use the Datrend API program vPad-IDE. Sample Checklists to control through the Interface are provided with the vPad-Check installation.
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 . Configuration statements can set limits for automatic Impulse 4000 pass/fail assessment, as well as to change settings for defibrillator and pacemaker tests.
Page 16
Impulse 4000 USER MANUAL Table 1 lists the permitted values for the command. Additionally, any limit type can be set to “lim” “none”, which disables automatic assessment for the affected test types. If the Interface receives a limit configuration command with a disallowed limit type, that particular limit will be disabled.
Impulse 4000 USER MANUAL 3.2.1.1 Example 1: Setting a Defibrillator Energy Limit To illustrate how the “lim” command is used, consider following statement: xctrl "Setting defib energy tol. to 10%" | lim1,target,10,percent For this statement, immediately following the “lim” command specifies the limit is for defib energy;...

Impulse 4000 USER MANUAL 3.2.2 Resetting Limits to Defaults The following vPL statement resets all limit settings to defaults: xctrl “< info >" | rslm where: is a descriptive message which is briefly displayed to the user. < info >...
Impulse 4000 USER MANUAL 3.2.3 ECG Simulation Impulse 4000 simulates ECG signals while conducting defibrillator and pacemaker tests. A Checklist may select an ECG waveform through the Interface. This is typically done prior to performing a defib or pacer test.

Impulse 4000 USER MANUAL 3.3 Defibrillator Tests Once a Checklist has initialized communication with the Interface, configured Impulse 4000 test settings and, optionally, prepared limits for automatic pass/fail assessment, vPad is ready to execute a range of defibrillator tests. A typical Checklist will include prompts instructing the operator how to set up the defibrillator and , followed by remote test statements.
