Accutorr Plus Service Manual 0070-10-0691 3 - 3Repair Information General Troubleshooting Guidelines3.3 General Troubleshooting GuidelinesThis procedure does not cover all possible problems. The intent of troubleshooting is toprovide quick isolation and remedy of malfunctions and to return the instrument promptlyto safe patient care. A logical approach will quickly identify the problem and suggest cost-effective solutions.3.3.1 Troubleshooting Tips1. Isolate the cause of the problem to be either clinical, instrument, or external. If aclinical cause is suspected, take the physiological measurement by a manual methodor use an alternate measuring device. Check the physiological value against theinstrument specifications; if it exceeds specification, continue with manual oralternate method.If a problem with the instrument is suspected, first examine and / or replace patientconnected accessories. Check instrument set-up / configuration. If all set-ups are OK,replace instrument with similar device.If the environment is suspected, observe if the malfunction coincides with otherequipment cycling (especially high-power motors, RF generators, etc.). Replaceproblem instrument with an identical substitute. Place the problem instrument in alow-disturbance environment. If the problem persists in the low-disturbanceenvironment, the instrument performance may be suspect. If the substitute instrumentexhibits similar poor performance in the original environment, the environmentalcauses must be eliminated.2. Use the proper equipment. See “Test Equipment Required” in section 3-4 for problemisolation and resolution. Similar devices may be used if they equal or exceedperformance standards of the equipment suggested.CAUTION: Soldering and solder removal equipment must below voltage operated and grounded to avoidstatic charge and stray current inducedcomponent damage. Maximum wattage: 25 W.3. Clean the repair area. After soldering operations, clean off the repaired area with ethylor methyl alcohol and a stiff hair brush. This will remove residual solder flux, makingthe repaired area more visible for an inspection and returning the instrument to itsoriginal, neat appearance. Removal of the flux will also facilitate making electricalmeasurements in the affected area as the flux itself is not conductive.3.3.2 Exchange ProgramA comprehensive circuit board and electro-mechanical module exchange program isavailable. The exchange circuits and modules are warranted, factory pre-tested andcalibrated. Final calibration of the exchange item is strongly suggested to match the newpart to the host system. See section 4.4 for details concerning the exchange program.
