4 Performance Tests and Calibration
Input Connections
Test connections to the instrument are best accomplished 
using the dual banana plug with copper wire short between 
two terminals for low- thermal offset measurement. Shielded, 
twisted- pair, Teflon interconnect cables of minimum length 
are recommended between the calibrator and the multimeter. 
Cable shields should be earth ground referenced. This 
configuration is recommended for optimal noises and settling 
time performance during calibration.
