To verify resistance using the 4-wire short:
1. With the 4-wire short still applied, select the Series 3700 4-wire resistance
function.
2. Select the SLOW integration rate with the RATE key.
3. Set the Series 3700 for the 1 range, and make sure the FILTER is on.
Enable OC+ (offset-compensated ohms). Use OC+ for 1 and 10 range
verification.
4. Verify the 1 range zero is within specification (see the 4-wire short applied
verification data (on page 14-26) table).
5. Set the Series 3700 for the 10 range (make sure the FILTER is on and
OC+ is still enabled).
6. Verify the 10 range zero is within specification (see the 4-wire short
applied verification data (on page 14-26) table).

Use the following values to verify the performance of the Series 3700. Actual
values depend on published specifications (see Calculating resistance reading
limits (on page 14-4)).
