Testing and Maintenance

4.1 Introduction

The expected service life of the equipment is five years. To ensure the equipment always functions normally, qualified service personnel should perform regular inspection, maintenance and test. This chapter provides a checklist of the testing procedures for the equipment with recommended test equipment and frequency. The service personnel should perform the testing and maintenance procedures as required and use appropriate test equipment.

The testing procedures provided in this chapter are intended to verify that the equipment meets the performance specifications. If the equipment or a module fails to perform as specified in any test, repairs or replacements must be done to correct the problem. If you have any question, contact our Technical Support Department.



CAUTION

All tests should be performed by qualified service personnel only.

Care should be taken to avoid changing the settings in [User Settings >>] and

[Factory Maintenance >>] menus to avoid loss of data.

Service personnel should acquaint themselves with the test tools and make sure that test tools and cables are available.

4.2 Performance Tests

Performance test are designed to ensure that measurement results are accurate. The following sections provide a list of performance and accuracy tests and their recommended frequencies.

4.2.1

If the user suspects that the nurse call function does not work well.

4-1

4.2.2

Visual Inspection

Perform an overall inspection on the appearance of the equipment. The test is passed if the equipment has no obvious signs of damage. Follow these guidelines when inspecting the equipment:

 Carefully inspect the case, display screen, buttons, and knob for obvious signs of damage.

 Inspect all external connections for loose connectors, bent pins or frayed cables.

 Inspect all connectors on the equipment for loose connectors or bent pins.

 Make sure that safety labels and data plates on the equipment are clearly legible.

4.2.3

SpO

test

Test Method 1

Tool required:

 None

Test procedure:

sensor for adult to the SpO

connector of the monitor. Set [Patient

Category] to [Adult].

2. Place the SpO

sensor on your finger.

3. Verify the Pleth Wave and Pulse Rate are displayed on the screen.

4. Remove the SpO

sensor from your finger and make sure that the SpO

Sensor Off alarm is triggered.

Measurement validation

The SpO

accuracy has been validated in human studies against arterial blood sample reference measured with a CO-oximeter. Pulse oximeter measurements are statistically distributed, and only about two-thirds of the measurements can be expected to fall within the specified accuracy compared to CO-oximeter measurements.

NOTE



The SpO

simulator can only be used to verify that the pulse oximeter operates properly. It cannot be used to verify the accuracy of the pulse oximeter or the SpO

2 sensor. To verify the accuracy, clinical tests are required.

4-2

Electrical Safety Inspection

The following electrical safety tests are recommended as part of a comprehensive preventive maintenance program. They are a proven means of detecting abnormalities that, if undetected, could prove dangerous to either the patient or the operator. Additional tests may be required according to local regulations.

All tests can be performed using commercially available safety analyzer test equipment. Follow the instructions of the analyzer manufacturer.

The consistent use of a safety analyzer as a routine step in closing a repair or upgrade is emphasized as a mandatory step if an approved agency status is to be maintained. The safety analyzer also proves to be an excellent troubleshooting tool to detect abnormalities of line voltage and grounding, as well as total current loads.
