Dc Zero Test - Fluke 5730A Calibration Manual

DC Zero Test

1. Short one end of a 5730A-7003 cable. This can be done by connecting both
spade lugs to a binding post but do not use the binding post on an instrument
that is powered, such as the Product, but instead use the 752A or a 742A.
Connect the other end to the Fluke 8508A Input HI and LO. Leave the shield
connection open.
2. Set the 8508A to dc V, 200 mV range, 7 digits, internal guard, filter IN and
"FAST" mode.
3. Wait for the reading to settle and then zero the meter using the Zero Rng
button.
4. Remove the short from the end of the cable and connect it to the Product
OUTPUT HI and LO and the shield to the guard terminal.
5. Connect the Product Guard and Ground together. Make sure the Product is
set to internal guard
6. Set the Product to the first zero test on the appropriate range as given in
Table 8.
For each new range tested:
1. Remove the range lock if set.
2. Set the Product to a near-full scale voltage on that range.
3. Set the range lock.
4. Set the zero voltage.
7. Push  on the Product.
8. Wait for the reading to settle and record it in the Table 8 DMM Reading
column.
9. Push  on the Product. Verify that the reading was within the limits
given.
10. Repeat steps 6 through 9 for the rest of Table 8.
