14 Functional Verification Welch Allyn Propaq Encore Vital Signs Monitor
2. Connect the high-voltage output lead of the tester to all ECG leads, using a dedicated
patient cable reserved for use only in such tests.
3. Connect the tester's chassis-connected return lead to the monitor's dc input
connector, using a suitable plug.
4. Apply the test voltage for one second. The tester must not indicate dielectric
breakdown.
Functional Verification
The functional verification must be done only when the monitor is fully assembled. If the
monitor has been stored for longer than one month without the monitor connected to the
ac adapter (for recharging), the battery voltage must be checked. The battery must be
replaced if it cannot hold a charge. Refer to
“Battery Capacity Check” on page 45.
Power System
The following steps check the integrity of the Encore’s power system.
1. Turn the ac power adapter’s power switch off.
2. Plug the ac power adapter into an ac mains receptacle and connect it to the Encore’s
right side panel dc power connector.
3. Check that the green LED charging indicator on the monitor’s right side panel is off.

WARNING If any dielectric breakdown occurs, do not use the monitor. All
internal sheet insulation barriers must be properly installed. Check the monitor to
determine the cause of dielectric breakdown; then repair the monitor or return
the monitor to Welch Allyn for repair.
Note
Some configurations of the Encore monitor do not include impedance
pneumography (RESP) and other neonatal monitoring parameters. In these
versions, RESP does not appear in menus or on the screen displays. You can
ignore RESP and other terms relating to neonatal monitoring when indicated in
the following instructions.
If you plan to use a Dynatech/Nevada model 213A, 215A, or 217A Patient
Simulator to simultaneously simulate ECG and invasive blood pressure, see
“Dynatech/Nevada Patient Simulator Modification” on page 125 for important
information.
Before starting the verification procedures, charge the battery for at least 8 hours
with the monitor turned off. (Charge for 12 hours if a Printer or SpO
2
module is
attached.)
