Input Connections
For low- thermal offset measurements, test connections to
the instrument are best accomplished by shorting the two
terminals using dual banana plug with copper wire short.
Shielded twisted- pair Teflon interconnect cables of minimum
length are recommended between the calibrator and the
multimeter. Cable shields should be grounded to earth. This
configuration is recommended for optimal noise and settling
time performance during calibration.
