Section 2-Functional Verification
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 Section 4 for a battery capacity test.
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 Appendix B 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
attached.)
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.
4. Turn on the power adapter's power switch.
5. Check that the green LED on the power adapter turns on and that the green LED charging
indicator on the monitor's right side panel turns on.
6. Disconnect the power adapter from the monitor. Check that the monitor's green LED charging
indicator on the right side panel turns off.
Caution
In the next steps, carefully check for the proper polarity of the connection between
the power supply and the monitor. If voltage is applied with the wrong polarity, it will
open the right side panel fuse (F1). Refer to the figure on page 26 to verify proper
polarity.
7. Set the dc power supply meter to Volts and turn the power switch on; set it for 15.0V ± 0.1V.
8. Turn off the dc power supply.
9. Using the Welch Allyn dc power supply adapter cable, refer to the figure below for polarity
and connect the dc power supply to the monitor's dc input connector on the right side panel.
