3.1 Introduction
3.2 Required Tools and Equipment
3.3 Performance Tests
This section describes performance verification and safety testing for the Nellcor
N-20PA pulse oximeter (monitor) and all options, following troubleshooting and
repairs.
The tests can be performed without removing the monitor cover. All tests except
Battery Operation must be performed before the monitor is returned to the user.
If the monitor fails to perform as specified in any test, repairs must correct the
discrepancy before the monitor is returned to the user.
The N-20PA is powered by alkaline batteries. The N-20PA design includes
built-in electrical isolation; no ground resistance or current leakage testing is
required. In addition, the N-20PA requires no calibration.

Tester, Pulse Oximeter
Variable DC power supply; 1 amp supply, voltage range 0-6 VDC
The procedures required to verify correct monitor performance are listed below:
3.3.1 Battery Performance
3.3.2 Power-Up Performance
3.3.3 Hardware and Software Tests
3.3.4 Backlight Test
3.3.5 Low Battery Test
3.3.6 Printer Test
The N-20PA will operate in diagnostic mode in conjunction with the Nellcor
pulse oximetry tester, model SRC-2 or SRC-1, to test instrument performance.
The SRC-2 plugs into the DB-9 sensor connector and uses the instrument's
power supply and diagnostic software to test the display and the operation of the
instrument. Mallinckrodt recommends routine performance testing at 1-year
intervals. Refer to the SRC-2 operator's manual for details on performance
testing with the SRC-2.
