vPad-XSC for Impulse 4000 USER MANUAL

1.3 Checklists and vPL

In vPad-Check, equipment maintenance and inspection procedures are called

Checklists

. 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. In this case, the remote instrument
is an

Impulse 4000

defibrillator and transcutaneous pacemaker analyzer.

In a Checklist, prompts and machine instructions are written as statements in

vPad Programming

Language

(vPL). A statement generally consists of a specific keyword followed by one or more

parameters. For example, the statement

xopen "Impulse 4000 XSC" | D | 5

initializes a data connection between the Interface and

Impulse 4000

using the keyword “

xopen

”. Other

statements are responsible for configuring and initiating tests through

Impulse 4000

.

Checklists can be written on the Android tablet, or on a personal computer (PC), using a text editor, or
using the Datrend vPad-IDE. Once a new Checklist has been written, it can be imported to vPad-Check
through a USB flash drive, via Bluetooth or a cloud service (Dropbox, Google Drive or OneDrive).
Further information on Checklists and vPL, including a full list of vPL keywords, is provided in the

vPad-

Check Operating Manual

which can be opened with the Datrend Docs app:
