Service manual

HI to Chassis Leakage 1. Make Hardware Connections
• Turn power supply and mainframe power OFF
• Connect DMM, power supply, and resistor as shown in
Figure 2-8
• Turn power supply and mainframe power ON
2. Check Direct Terminals Leakage
• Send *RST to FET Multiplexer
• Send TRIG SGL to DMM
• Record the DMM reading in Table 2-1
Positive Polarity, HI to Chassis, Direct
• The DMM measurement should be less than 0.010 Vdc.
A measurement out of this range indicates a failure of the
FET Multiplexer
