* Calculate limits based on actual characterized resistance values and Model 7751 resistance accuracy
specifications. See Verification limits.
Set the Model 7751/7753 source voltage to 500V as follows:
a.
Press SHIFT, CARD, then CONFIG.
b.
Select SLOT1: 7751 or SLOT1: 7753, then press ENTER.
c.
Select the V-C submenu, then set the source to 500V.
d.
Press EXIT to return to normal display.
Using the CLOSE key, close the following slot 2 channels: 1, 2, 16, 18, 21, 22,
and 23.
Set the math function to display resistance as follows:
a.
Press SHIFT then MATH.
b.
Select S1VOHMS, then press ENTER.
c.
Press EXIT to return to normal display.
Recalculate reading limits shown in
based on the actual characterized resistance value.
Verify that the resistance reading is within the limits calculated in step 6.
Repeat steps 1 through 7 for the remaining resistances and voltage source settings
as shown in
