Verifying four-wire resistance
Check the normal resistance function by connecting accurate resistance values to the Series
3700 analog backplane connector and verify that the displayed readings fall within specified
limits.
CAUTION
Do not exceed 300V peak between INPUT HI and INPUT LO because
instrument damage may occur.
To verify four-wire resistance accuracy:
1. Using shielded, Teflon-insulated or equivalent cables in a 4-wire configuration, connect the
Series 3700 INPUT and SENSE pins to the calibrator as shown for 100
-10M
ranges.
2. Set the calibrator for 4-wire resistance with external sense on.
3. Select the Series 3700 4-wire resistance function.
4. Select the SLOW integration rate with the
RATE
key.
5. Set the Series 3700 for the 100
range, and make sure the FILTER is on. Enable OC+
(offset-compensated ohms). Use OC+ for 100
range verification.
6. Recalculate reading limits based on actual calibrator resistance values.
