SC 7000 and SC 9000XL monitors are battery operated devices,
functionally grounded through CPS or IDS power supply when operated
from a docking station. Leakage current tests assure that under both
normal and fault conditions, any leakage current does not exceed values
given inTable 4-3.
1) Perform leakage current tests with monitor on a docking station, and
CPS, IDS Power Supply, or PSL plugged into leakage tester. See

Figure

4-4.
2) Follow leakage tester manufacturer's instructions to measure each of
leakage currents given in
• open ground
• reversed polarity
• open ground reversed polarity
