Functional Verification - Welch Allyn PROPAQ CS Service Manual

Service Manual

Functional verification

Perform the functional verification with the monitor 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
Note
Power system
The following steps check the integrity of the monitor'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 monitor'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.
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.
"Battery capacity check"
See Update to Directions for Use, software version 3.6X and greater, for changes
to patient alarms and equipment alerts.
Impedance pneumography (RESP) is an optional feature. Ignore references to
RESP in this procedure if it is not installed.
If you plan to use a Fluke (Dynatech/Nevada) model 213A, 215A, or 217A Patient
Simulator to simultaneously simulate ECG and invasive blood pressure, see
"Fluke patient simulator modification"
Before starting the verification procedure, charge the battery for at least 8 hours
with the monitor turned off. (Charge for 12 hours if a printer or SpO
attached.)
Caution In the next steps, carefully check for proper polarity of the connection
between the power supply and monitor. If voltage is applied with the wrong
polarity, it will open the right side panel fuse (F1). Refer to the figure below to
verify proper polarity.
