8. Maintenance Tests Overview The M Series has two checkout procedures the operator s shift checklist and the extensive six month maintenance tests checkout procedures Because the M Series units must be maintained ready for immediate use it is important for users to conduct the Operator s Shift Checklist procedure at the beginning of every shift This procedure can be completed in a few minutes and requires no additional test equipment See the ZOLL M Series Operator s Guide for the Operator s Shift Checklist A qualified biomedical technician must perform a more thorough maintenance test checkout every six months to ensure that the functions of the M Series unit work properly This chapter describes the step by step procedures for performing the six month maintenance test checkout Use the checklist at the back of this document ZOLL M Series Maintenance Tests Checklist to record your results of the maintenance tests This chapter describes the following maintenance tests 1 Physical Inspection of the Unit 2 Front Panel Button Test 3 5 and 12 Leads Test Power Supply Test Leakage Current Test Paddles Test Heart Rate Display Test Calibrating Pulses on Strip Chart Test Notch Filter Test 10 Heart Rate Alarm Test D VOD 00 10 tA FW WN M Series Service Manual 11 Defibrillator Self Test 12 Synchronized Cardioversion Test 13 Shock Test 14 Summary Report Test 15 Advisory
