11 3 Functional Verification Introduction The functional verification procedures ensure proper operation of the Encore monitor and its options. These procedures should be performed following module-level repairs, calibration, or whenever there is a question about the accuracy or safety of the patient functions. Use the calibration procedures (“Calibration” on page 33) to return the monitor to operation within its performance specifications.
12 Functional Verification Welch Allyn Propaq Encore Vital Signs Monitor Required Equipment You will need the following equipment to verify that all functions of the Encore operate correctly. All test equipment must be calibrated to function within parameters specified by the manufacturer, and must be traceable to a national calibration standard. Some equipment can be manufactured. See “Manufacturable Test Equipment” on page 123 for information on manufacturable test equipment. Table 3.
Service Manual Functional Verification Note 13 A hi-pot test is only required if the monitor has been opened. Risk (Leakage) Current Test A risk (leakage) current test must be performed to verify that the patient remains electrically isolated from the power circuits of the Encore. Check leakage currents using a Dynatech/Nevada 431F-1D safety analyzer or its equivalent. The source current should not exceed 10A rms.
