12 Functional Verification Welch Allyn Propaq Encore Vital Signs Monitor
Required Equipment
You will need the following equipment to verify that all functions of the Encore operate
correctly. All test equipment must be calibrated to function within parameters specified
by the manufacturer, and must be traceable to a national calibration standard.
Some equipment can be manufactured. See “Manufacturable Test Equipment” on
page 123 for information on manufacturable test equipment.
Safety Tests
The following two safety tests, a risk (leakage) current safety check and a dielectric
strength integrity (hi-pot) test, must be performed whenever the Encore has been opened
for calibration or repair.
