Ground Wire Leakage Current Test Procedure

To test the system’s ground wiring for leakage:

1.Set the mode on the analyzer to detect leakage.

2.Plug the analyzer into an available wall outlet. Plug the ultrasound system power plug into the test receptacle on the analyzer. Turn on the ultrasound system’s power by starting the internal PC.

3.Take ground wire leakage current measurements in an open ground condition, with both normal and reverse polarity. Record the highest value, and compare it to the limit specified for Normal condition in Figure 6-2on page 93.
