ATLAS PATIENT MONITOR - SELF TEST- FUNCTIONAL TEST - BP TEST [MEDICAL EQUIPMENTS]

SELF TEST [POWER ON]

• Plug in Atlas into AC power with no sensors attached. Verify that the AC~ LED indictor is lit. Install paper in printer if fitted.

Turn on power and verify the following:

• Green light in power button.
• Loud beep when Power On button pressed.
• Three dashes in SYSTOLIC.
• Three dashes in DIASTOLIC.
• Two dashes in SpO2  (takes several seconds after BP dashes come on).
• Three dashes in PULSE (takes several seconds after BP dashes come on).
• Single bar at the bottom of  Plethysmograph.
• No lights in TEMP.
• No lights in ALARMS OFF buttons.
• X lit on AUTO.
• CRT display may comes on slowly if cold or quickly if still warm from last use.
• May see version string in center if comes on quickly. It isn't a problem if not seen because it comes on slowly.

On the CRT you should see:

• Three dashes for Heart Rate
• Heart symbol
• Lead select symbol
• Scale bar
• One or two lines of dashes for wave-forms – depends upon settings.
• Three dashes for MAP – or blank, depending upon settings.
• Error message /(s) at bottom of screen?

On models 622 or 623, disconnect AC cable. You should see no change except the AC~ LED indicator will not be lit. If you see warnings of a low, very low or depleted battery, or if the system turns off by it’s self, plug the Atlas back into the AC outlet and let the unit charge with unit turned off. Repeat test in 2 hours.

• Plug the monitor back into AC

MENU FUNCTIONAL TEST

• Press DATE/TIME button to enter menu page. Press TREND button to access the Advanced Configuration menu.
• Write down all configuration settings so that they can be reset to customer preferences later. If you have a printer press the PRINTER button to print out customer configuration settings.
• Set language to your native tongue if necessary to allow you to write down the other settings. The top item is always the language, press either SET buttons to step through list.
• Press TREND button to return to idle screen. Press DATE/TIME button and verify that date and time are correct. Set date and time if necessary.

NOTE:An incorrect date may indicate a battery problem. If date was incorrect, turn off unit, disconnect AC power cable, wait 5 minutes then reconnect the power cable. Turn Atlas on. Check date again. If date comes back incorrect on model 621 then replace main board. On model 622 and 623, if battery was not dead then replace main board.

• Press DATE/TIME button to return to waveform screen if needed.
• Press DATE/TIME button then press LEAD SELECT button to access service mode
• Version/configuration data is in lower half of menu, write it all down.
• Press SELECT button to highlight reset to factory defaults.
• Press BP START/CANCEL button to reset configuration.
• Press TREND button to return to idle screen.
• Press DATE/TIME button then press TREND button to access the Advanced Configuration menu.
• Set language to your native tongue if necessary

NOTE: We have just reset the monitor to factory defaults. Compare settings to factory defaults appropriate for the country in Operator manual. If the factory defaults do not match then that may indicate a memory problem. Changing only the language should not change any of the other factory default settings.

• Press DATE/TIME button then press LEAD SELECT button to access service mode.
• Press SELECT button to highlight CRT test pattern.
• Press BP START/CANCEL button to show test pattern. Examine display. Press any key to end display.
• Press Select button to highlight Printer test pattern (if fitted). Press BP START/CANCEL button to start test pattern. Printer should print a test pattern. Press any key to end  display. Examine printout.
• Press SELECT button to highlight LED test. Press AUTO button to turn on all LEDs.  Press BP START/CANCEL button to show automatic test pattern. Watch for a while, look for glitches in pattern. Press SET button to go to manual mode and step through individual segments if needed to observe a problem.
• Press SELECT button to highlight Button test. Press BP START/CANCEL button to start test. Press every button on system, press BP ART/CANCEL button last.
• Verify that buttons match up with their names and that all buttons are functional.

NOTE:If name does not correspond to the button pushed then this may indicate memory corruption. You may need to replace the main board.

• Press SELECT button to highlight Display A/D channels. Press SET button and write down all values for each of the four screens for later review. Press TREND button to return to idle screen.

BP TEST

• Press DATE/TIME button then press TREND button to access the Advanced Configuration menu. Press SELECT button to highlight Initial pressure. Press SET button to change Initial pressure to 280 mmHg. Press SELECT button to highlight MAP. Press SET button to change MAP to Yes. Press TREND button to return to idle screen.
• Connect the BP port to the BP simulator. Set the simulator for a normal reading (140/80, 100BPM, NSR). Press BP START/CANCEL button. Atlas should start to pump and display a manometer value in SYSTOLIC LED. This value should track and be very close to pressure displayed by manometer on BP simulator (if fitted).  Largest number shown in SYSTOLIC LED should be very close to the initial pressure setting recorded above from Advanced Configuration. System should start stepping down pressure, showing step values in SYSTOLIC LED display. It then should display the correct SYSTOLIC and DIASTOLIC values. System may show MAP value depending upon country language setting.
• Press BP START/CANCEL button. System should start pump, display manometer value in SYSTOLIC LED. This value should track and be very close to pressure displayed by manometer in BP simulator (if fitted). Largest number shown in SYSTOLIC should be very close to the Initial pressure setting of 280 mmHg. If pressure shown exceeds 300 mmHg then re calibrate the Atlas BP.
• System should start to step down pressure, showing step values in SYSTOLIC LED and then display correct SYSTOLIC and DIASTOLIC values. System should show MAP value. MAP value should match what simulator shows.
• Set simulator to (120/70, 60(beats per minute)bpm, NSR).
• Press the AUTO button. The X manual BP cycle indicator will go out and the 1 minute auto BP cycle indicator will flash for 10 seconds. 20 seconds after the 1 minute auto BP cycle indicator stops flashing, BP measurement starts.
• Verify the BP reading. If BP measurement incorrect re-calibrate.
• No less than 30 seconds after completing the measurement another measurement should start. While it is pumping up, press the BP START/CANCEL button.
• Measurement should stop immediately and pressure should be dumped (as seen on the simulator manometer).
• Press AUTO button and X manual BP cycle indicator should light (not flashing).
• Disconnect the tubing from the BP port on the Atlas. Press BP START/CANCEL button and note the time (to the second) when the Atlas aborts the BP cycle and gives you an alarm. It should take no longer than 1 minute. Turn Atlas off.
