4.Make the appropriate connections between the analyzer and the ground lug on the ultrasound system’s I/O panel.

5.Read chassis ground resistance in milliohms. Flex the ultrasound power cord during the test to detect intermittent changes in resistance value.

6.Record the highest resistance value measured in step 5. Check that the highest resistance value is within the limit specified in Figure 6-1on page 91.

NOTE If the reading exceeds the specified limit, check the power cord and the associated primary wiring.

CAUTION

WARNING

A comprehensive ground impedance measurement can be performed using the safety analyzer. The impedance test drives a load current through the ground wire while measuring the AC voltage drop across the entire length of the power cord and to the system chassis. The reading will be in milliohms.

This test checks the entire system for leakage on chassis ground wires. Figure 6-2on page 93 shows the basic electrical concept of the test. Use a safety analyzer and complete the procedure that follows the figure.

If the safety analyzer is used for an extended period, it may be damaged by the high current draw of the system.

This test can be hazardous. Avoid any contact with line voltage. Any time during the test that the ground connection is open, do not touch the M2540A chassis or the patient cable.
