Section 2: Operation
Current measurement range and compliance limit
To make the most accurate resistivity measurement, the 6517 must be on the most sensitive
(optimum) current measurement range. Place the 6517 in autorange to do this.
A current compliance limit protects the device under test (DUT). For almost all resistivity tests,
protecting the specimen from excessive current is not a concern.
If manual ranging must be used, you may have to experiment to determine the best measurement
range and subsequent compliance limit. For detailed information on compliance and measurement
range selection, refer to the 6517 or 6517B reference manuals.
Electrification time
Electrification time is the total time that the specified voltage is applied to the specimen when the
current measurement is made. For example, for an electrification time of 60 seconds, the current
measurement is made after the specimen was subjected to the applied voltage for 60 seconds. Keep
in mind that experimentation may dictate a different electrification time. Unless otherwise specified, an
electrification of 60 seconds is recommended.
Resistivity measurement procedure
The previously detailed operating information is integrated into the following procedure to make
resistivity measurements.
The following procedure uses hazardous voltage that could cause severe injury or death.
Exercise extreme caution when the voltage source is in operate.
To calculate volume resistivity, the average thickness of the specimen must be known. If thickness is
not known, use calipers to measure it.
