Leakage Current Hot Check (Figure 1-1): 1. For continued safety, do not attempt to modify the WARNING: Do not use an isolation transformer during circuit board. this test. 2. Disconnect the AC power before servicing. Use a leakage current tester or a metering system 3. When the chassis is operating, semiconductor that complies with American National Standards heatsinks are potential shock hazards. Institute (ANSI C101.1, Leakage Current for Appliances), and Underwriters Laboratories (UL 1-1-1 Servicing the High Voltage and CRT : Publication UL1410, 59.7). WARNING:A high voltage adjusted to the wrong 4. With the unit completely reassembled, plug the AC value may cause excessive X-ray line cord directly into a 120V AC outlet. With the emissions. unit's AC switch first in the ON position and then 1. When servicing the high voltage system, remove OFF, measure the current between a known earth the static charge by connecting a 10 kohm resistor ground (metal water pipe, conduit, etc.) and all in series with an insulated wire (such as a test exposed metal parts, including: metal cabinets, probe) between the chassis and the anode lead. screwheads and control shafts. The current measured should not exceed 0.5 milliamp. Reverse 2. When troubleshooting a monitor with excessively the power-plug prongs in the AC outlet and repeat HV, avoid being unnecessarily close to the monitor. the test. Do not operate the monitor for longer than is necessary to locate the cause of excessive voltage. (READING SHOULD NOT BE ABOVE 0.5mA) 3. High voltage should always be kept at the rated value,
