4. Use the balloon pump to inflate until the reading of the sphygmomanometer approximates to the preset
calibration value.
5. Adjust the calibration value in the Maintain IBP menu until it is equal to the reading of sphygmomanometer.
6. In the
Cal. IBP Press.menu, select the Calibrate button next to the target IBP channel to start calibration.
If the calibration succeeds, the message "Calibration Completed!" is displayed. If the calibration fails, a corresponding
message is displayed.
5.5 Analog Output Test
Tools required:
Patient simulator Medsim300B, MPS450, or equivalent equipment
Oscilloscope
1. Connect the patient simulator to the monitor using an ECG or IBP cable.
2. Connect the oscilloscope to the Auxiliary Output Connector on the monitor.
3. Verify that the waves displayed on the oscilloscope are identical with those displayed on the monitor.
5.6 Electrical Safety Tests
WARNING
Electrical safety tests are a proven means of detecting abnormalities that, if undetected, could prove
dangerous to either the patient or the operator.
All tests can be performed using commercially available safety analyzer test equipment. Maintenance personnel
shall ensure the adaptability, functional completeness and safety of the test equipment, and be familiar with their
usage.
Electrical safety tests shall comply with the latest versions of the following standards: EN 60601-1 and
UL60601.
In case of other stipulations in local laws and regulations, implement electrical safety tests by following
relevant stipulations.
All devices driven by AC power and connected to medical instruments in patient zones must comply with
the IEC 60601-1 standard. And electrical safety tests on these devices must be implemented in
accordance with the test interval of the monitor.
Electrical safety tests are used to timely detect potential electrical safety risks that might cause injuries to patients,
operators or maintenance personnel. Electrical safety tests must be carried out under normal environmental conditions
(that is, normal temperature, humidity and barometric pressure).
The electrical safety tests described in this chapter take the Bio-Tek 601 safety analyzer as an example. The safety
analyzer used in different regions may vary. Make sure that the electrical safety test scheme you adopted is applicable.
