Models 6517 and 6517B Electrometer/High Resistance Meters
The Model 8009 Resistivity Fixture is designed to fully support the enhanced
resistivity measurement capability of the Model 6517 and Model 6517B
Electrometer/High Resistance Meters. Models 6517 and 6517B employ the
ASTM D-257 measurement method, and display measurements in resistance,
surface resistivity, or volume resistivity. All the Model 8009 electrode constants
are programmed into Models 6517 and 6517B. A built-in high voltage source
provides test voltages up to 1000 volts.
Models 6517 and 6517B offer special features for sophisticated, precise
measurement of resistivity. Both models can automatically implement a “bias-
measure” sequence in which the test voltage is applied for a programmed time to
permit resistivity to reach equilibrium, after which the measurement can be made
at some desired voltage. Models 6517 and 6517B can also measure and record
