2. Ensure all relays are open

• Send *RST to Module

• Trigger the DMM with TRIG SGL and note reading

• DMM reading should indicate an open condition (> 1.2 G Ω )

3. Measure Column 00 to Row 00 HI path resistance

• Send CLOS (@nn0000) to close column 0 row 0, where nn = card

# (typically 01)

• Trigger the DMM with TRIG SGL and note reading

• Send OPEN (@nn0000) to open column 0 row 0, where nn = card

# (typically 01)

• Enter the result in Table 2-1 for column 0 row 0

4. Repeat for all Columns

• Repeat step 3 for all columns

• Use CLOS (@nn00cc) and OPEN (@nn00cc), where nn = card #

and cc= column # (omit leading zeroes in nn)

For E1465A use column numbers 01 through 15

For E1466A use column numbers 01 through 63

For E1467A use column numbers 01 through 31

5. Repeat for all Rows

• Repeat steps 3 and 4 for all rows

• Use CLOS (@nnrrcc) and OPEN (@nnrrcc), where nn = card #,

rr = row #, and cc= column # (omit leading zeroes in nn)

For E1465A use row numbers 01 through 15

For E1466A use row numbers 01 through 03

For E1467A use row numbers 01 through 07

Column LO to Row LO

Measurements 1. Make Hardware Connections

• Turn mainframe power OFF

• Set DMM to measure 4-wire Ohms

• Connect DMM leads as shown in Figure 2-5

• Turn mainframe power ON

2. Repeat steps 2 through 5 of the "Column HI to Row HI

Measurements"
