External Repairs
External repairs consist of repairs or replacements of one or more items. Repair or replacement
of these items does not require you to open the cardiograph case, therefore only a limited
number of tests are necessary to verify performance post-repair. External repairs that involve
the PIM, PIM data cable, and PIM lead set require an ECG simulation test to verify proper
ECG signal path.
The typical external repairs include:
PIM
Patient Leads
PIM data cable
Labels
Batteries
Paper Tray
AC Power Cord
AC Power Supply
Wireless LAN card
USB external devices
Barcode reader
Trolley
External cables
Refer to Table 4-1 for the required test blocks that must be performed after any external repair
occurs.
Internal Repairs
If the case was opened, regardless of the repair, you must perform additional Performance
Verification Tests. Refer to Table 4-1 for the required test blocks that must be performed after
any internal repair.
