Remove the SpO2 sensor from your finger and make sure that an alarm of SpO2 Sensor Off is triggered. Measurement validation The SpO2 accuracy has been validated in human studies against arterial blood sample reference measured with a CO-oximeter. Pulse oximeter measurements are statistically distributed, and only about two-thirds of the measurements can be expected to fall within the specified accuracy compared to CO-oximeter measurements. NOTE The SpO2 simulator can only be used to verify that the pulse oximeter operates properly. It cannot be used to verify the accuracy of the pulse oximeter or the SpO2 sensor. To verify the accuracy, clinical tests are required. 4-3

83 A Electrical Safety Inspection The following electrical safety tests are recommended as part of a comprehensive preventive maintenance program. They are a proven means of detecting abnormalities that, if undetected, could prove dangerous to either the patient or the operator. Additional tests may be required according to local regulations. All tests can be performed using commercially available safety analyzer test equipment. These procedures assume the use of a 601PROXL International Safety Analyzer or equivalent safety analyzer. Other popular testers complying with IEC used in Europe such as Fluke, Metron, or Gerb may require modifications to the procedure. Follow the instructions of the analyzer manufacturer. he electrical safety inspection should be periodically performed every two years.the safety analyzer also proves to be an excellent troubleshooting tool to detect abnormalities of line voltage and grounding, as well as total current loads. A.1 Power Cord Plug A.1.1 The Power Plug Test Item The power plug The power cord The power plug pins The plug body The strain relief The power plug Acceptance Criteria No broken or bent pin. No discolored pins. No physical damage to the plug body. No physical damage to the strain relief. No plug warmth for device in use. No loose connections. No physical damage to the cord. No deterioration to the cord. For devices with detachable power cords, inspect the connection at the device. For devices with non-detachable power cords, inspect the strain relief at the device.

No physical damage to meters, switches, connectors, etc. No residue of fluid spillage (e.g., water, coffee, chemicals, etc.). No loose or missing parts (e.g., knobs, dials, terminals, etc.). A-1

84 A.2.2 Contextual Inspection Test Item The enclosure and accessories Acceptance Criteria No unusual noises (e.g., a rattle inside the case). No unusual smells (e.g., burning or smoky smells, particularly from ventilation holes). No taped notes that may suggest device deficiencies or operator concerns. A.3 Device Labeling Check the labels provided by the manufacturer or the healthcare facility are present and legible. Main unit label Integrated warning labels A.4 Protective Earth Resistance Protective Earth Resistance is measured using the RED test lead attached to the DUT Protective Earth terminal or enclosure. Select the test current by pressing SOFT KEY 3 to toggle between 1AMP, 10AMP, and 25AMP. The front panel outlet power is turned off for this test. The following conditions apply: L1 and L2 Open. Preparation 1. First select the test current that will be used for performing the Protective Earth Resistance test by pressing AMPERES (SOFT KEY 3). 2. Connect the test lead(s) between the RED input jack and the GREEN input jack. 3. Press CAL LEADS. The 601PRO will measure the lead resistance, and if less than Ohms, it will store the reading and subtract it from all earth resistance readings taken at the calibrated current. If the calibration fails, the previously stored readings will be used until a passing calibration has occurred.: WARNING During Earth Resistance testing, the DUT must be plugged into the 601PRO front outlet. If the DUT fails Earth Resistance, discontinue tests and label the device defective. A-2

85 To Perform the Test 1. From the MAIN MENU, or with the outlet unpowered, plug the DUT into the 601PRO front panel outlet. 2. Attach the 601PRO RED input lead to the device s Protective Earth terminal or an exposed metal area. 3. Press shortcut key 3. The Protective Earth Resistance test is displayed. 4. Press SOFT KEY 3 to select a test current (1AMP, 10AMP, or 25AMP). The selected test current is displayed in the upper right corner of the display. 5. Press START TEST to start the test. The test current is applied while resistance and current readings are taken. This takes approximately 5 seconds. 6. Press the print data key at any time to generate a printout of the latest measurement(s). NOTE When "Over" is displayed for Ohms, this signifies that a valid measurement was not obtained because either an open connection was detected or that the measurement was not within range. Readings greater than Ohms will be displayed as Over. In Case of Failure Once it reaches the limitation, stop using and inform the Customer Service Engineer for analysis and disposal. LIMITS ALL COUNTRIES R = 0.2 Ω Maximum A.5 Earth Leakage Test Run an Earth Leakage test on the device being tested before performing any other leakage tests. Leakage current is measured the following ways: Earth Leakage Current, leakage current measured through DUT outlet Earth Earth Leakage Current AP-EARTH (ALL Applied Parts connected to Earth), leakage current measured through DUT outlet Earth There is no need to attach a test lead; the 601PRO automatically connects the measuring device internally. A-3

86 To Perform the Test 1. From the MAIN MENU, or with the outlet unpowered, plug the DUT into the 601PRO front panel outlet, and turn on the device. 2. Attach the device's applied parts to the 601PRO applied part terminals if applicable. 3. Press shortcut key 4.The Earth Leakage test appears on the display, and the test begins immediately: SOFT KEY 1 toggles the DUT outlet Polarity from Normal to Off to Reverse. SOFT KEY 2 toggles the DUT outlet from Earth to No Earth. SOFT KEY 3 toggles the DUT outlet from L2 to No L2. SOFT KEY 4 toggles the AP to Earth to No AP to Earth. 4. Press the print data key at any time to generate a printout of the latest measurement. In Case of Failure Check any broken of the enclosure. Replace any defective part. Inspect wiring for bad crimps, poor connections, or damage. Test the wall outlet; verify it is grounded and is free of other wiring abnormalities. Notify the user or owner to correct any deviations. As a work around, check the other outlets to see if they could be used instead. Change another probe to confirm if the fail is caused by console. If the leakage current measurement tests fail on a new unit and if situation can not be corrected, submit a Safety Failure Report to document the system problem. Remove unit from operation. If all else fails, stop using and inform the Customer Service Engineer for analysis and disposal.

87 A.6 Patient Leakage Current Patient leakage currents are measured between a selected applied part and mains earth. All measurements have a true RMS only response. Preparation Perform a calibration from the Mains on Applied Part menu. The following outlet conditions apply when performing this test: Normal Polarity, Earth Open, Outlet ON Normal Polarity, Outlet ON Normal Polarity, L2 Open, Outlet ON Reversed Polarity, Outlet ON Reversed Polarity, Earth Open, Outlet ON Reversed Polarity, L2 Open, Outlet ON WARNING If all of the applied parts correspond to the instrument type, the applied parts will be tied together and one reading will be taken. If any of the applied parts differ from the instrument type, all applied parts will be tested individually, based on the type of applied part. This applies to Auto and Step modes only. To Perform the Test 1. From the MAIN MENU, or with the outlet unpowered, plug the DUT into the 601PRO front panel outlet, and turn on the device. 2.
