3. Check Channels Leakage
• Send CLOS(@nn00) to the FET Multiplexer, where nn is the
channel number (typically 01)
• Send TRIG SGL to DMM
• Record the DMM reading in Table 2-1
Positive Polarity, HI to Chassis, Channels
• Send OPEN (@nn00) to the FET Multiplexer
4. Check Tree Leakage Current
• Send SCAN:PORT ABUS to the FET Multiplexer
• Send CLOS(@nn00) to the FET Multiplexer to close channel
00 and Tree A, where nn is the card number (typically 01)
• Send TRIG SGL to DMM
• Record the DMM reading in Table 2-1
Positive Polarity, HI to Chassis, Tree A
• Send OPEN (@nn00) to the FET Multiplexer
