Introduction
This section contains basic information on electrometer, high-resistance meter, and V-source
connections. The use of low-noise cables and shielding is also covered here. The concepts of
guarding and floating circuits are introduced as well.
Detailed connection schemes are included with the measurement procedures in
(on page 4-1).
Hazardous voltages may be present on the output and guard terminals. To prevent
electrical shock that could cause injury or death, NEVER make or break connections to the
Model 6517B while the output is on. Power off the equipment from the front panel or
disconnect the main power cord from the rear of the Model 6517B before handling cables
connected to the outputs. Putting the equipment in standby mode does not guarantee that
the outputs are not powered if a hardware or software fault occurs.
Electrometer input connector
The rear-panel triaxial INPUT connector is a 3-lug female triaxial connector that mates to a cable
terminated with a 3-slot male triaxial connector.
