Performance tests
Termination resistance measurement
Many of the performance tests use a BNC-dual banana adapter and 50 Ω BNC
feed-through terminator connected to a DMM.
For accuracy, the termination resistance of this connection is used in the
calculations.
Use this procedure and note the measured value for use in these procedures.
1. Connect the BNC-dual banana adapter and 50 Ω BNC feed-through terminator
to the HI and LO inputs of the digital multimeter.

2. Set the digital multimeter to the Ω 2wiresmode.
3. Measure the resistance and note the value as Term_R.
Keep this value available for use in several performance check calculations.
4. Set t
he digital multimeter to the DCV mode.
NOTE. Lead resistance is not included in the measurement results when using
four wire ohms. The accuracy is higher especially for small resistances. Use a
four wire method if necessary.
