•The ECG Lead Leakage Current test checks ECG leads connected to the optional Physio module for electrical leakage. See “ECG Lead Leakage Current Test (Source)” on page 94.

•The ECG Lead Isolation Leakage test checks ECG leads by applying voltage from the mains to the leads, to assure that the system is isolated from such voltages. See “ECG Lead Isolation Leakage Current Test” on page 96.

•The Transducer Leakage Current test checks a transducer for electrical leakage while it is connected to the ultrasound system. The system sends normal operating voltages to the transducer, which is tested for leakage. See “Transducer Leakage Current Test Procedure” on page 100.

•The Transducer Isolation Leakage Current test checks a transducer for electrical leakage by applying mains voltage to the leads, and checking the transducer for leakage. See “Transducer Isolation Leakage Current Test” on page 102

All tests can be performed using commercially available safety analyzer test equipment. Basic measurements can be performed with multifunction instruments like the HP 3469A multimeter.

Chassis to Ground Resistance Test

NOTE These procedures require a safety analyzer. Routinely use a safety analyzer as a final step in any repair or upgrade, to maintain agency approved status. The safety analyzer is also useful in detecting abnormalities of line voltage, grounding, and total current loads. Follow the instructions of the analyzer manufacturer.

The limits referenced in these tests are prescribed by UL, CSA, and IEC. Local regulations may require additional tests.

This test checks the entire system for electrical resistance between the chassis and ground. Figure 6-1on page 91 shows the basic electrical concept of the ground resistance test. Use a safety analyzer and complete the procedure that follows the figure.
