Maintenance Schedules
10.2
The electronic circuits within the Novametrix Model 520A Pulse Oximeter monitor
do not require scheduled calibration or service. However, in order to maximize
battery life, the monitor’s internal battery should be exercised monthly. Novametrix
recommends the following maintenance schedules.
1
• Cleaning and Sterilization:
Perform as required. See Cleaning and Sterilization on page 36.
• Battery Life and Maintenance:
See Battery Life and Maintenance on page 37.
• Functional Test:
The test may also be used as a “spot check” to verify system operation if reports
of malfunctions are received. The test verifies overall functional integrity of the
monitor and sensors. Section 12,
Functional Test , on page 51
• Accuracy Test:
This test, which requires the use of the Model TB500B Sensor Simulator,
verifies the performance accuracy of the Model 520A. If the monitor does not
pass the accuracy test, the Calibration and Adjustment test should be performed.
See Section 13,
Accuracy Test , on page 55.
• Calibration Tests:
These tests contain information on calibrating the electronic circuits within the
Model 520A and should only be performed if the monitor fails to pass the
Functional and/or Accuracy Tests. Only qualified service personnel should
attempt to perform the Calibration and Adjustment Test. See Section 14,
Calibration Tests , on page 59.
