Dry circuit resistance verification data
Use the following values to verify the performance of the Series 3700. Actual values are
dependent on published specifications (see
3)).
Applied Resistance
Verify Dry Circuit 100 Ohm
Verify Dry Circuit 1k Ohm
Verify Dry Circuit 2k Ohm

Verifying 1-OHM and 10-OHM resistance ranges

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
To verify normal resistance accuracy:
1. Connect the 1 discrete resistor to the Series 3700 input.
2. For the dry circuit test points, enable the dry circuit resistance attribute (DRY+).
