Use and ESD 

• Before connecting any coaxial cable to an instrument connector for the first 

time each day, momentarily short the center and outer conductors of the cable 
together. 

• Personnel should be grounded with a 1 M

 resistor-isolated wrist-strap before 

touching the center pin of any connector and before removing any assembly 
from the instrument. 

• Be sure that all instruments are properly earth-grounded to prevent build-up 

of static charge.
