Chassis-to-Ground Resistance Test Procedure
➤ To test the system for resistance between chassis and ground
1. Inspect the power cord for cracks and wear.
2. Set the mode on the analyzer to measure resistance in the power cord.
3. Plug the analyzer into an available AC wall outlet. Plug the ultrasound system power plug into
the test receptacle on the analyzer.
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.
