Test Equipment
These procedures use external, traceable signal sources to directly test character-
istics that are designated as checked (
n
) in the Specifications chapter of this
manual. Table 4--1 shows the required equipment list. Always warm up the
equipment for 30 minutes before beginning the procedures.

The capacitor is installed across the Data Precision 8200 output terminals to reduce noise. If your voltage reference
produces <4 mVp-p of noise, external noise reduction is not necessary.
