sal on most materials (i.e., by discarding the first three readings.) For example, a 1mm-thick sample
of 10
14
Ω-cm material can be measured with 0.3% repeatability in the 8009 Test Fixture, provided the
background current changes less than 200fA over a 15-second
p
eriod.
Simple DMM-like Operation
The 6517B is designed for easy, DMM-like operation via the front panel, with single-button control of
im por tant functions such as resistance measurement. Also, all the functions of the 6517B can be pro-
grammed through either the RS-232 interface or the GPIB (IEEE-488) interface.
High Accuracy High Resistance Measurements
The 6517B offers a number of features and capabili ties that help ensure the accuracy of high
resistance mea
sure ment applications. For example, the built-in volt age source simplifies determining
the relation
sh
ip between an insulator’s resistivity and the level of source voltage used. It is well-
suit ed for capacitor leakage and insulation resistance mea sure ments, tests of the surface insulation
resis tance of printed circuit boards, voltage coefficient test ing of resistors, and diode leakage
characterization.
Temperature and Humidity Stamping
Humidity and temperature can influence the resist ivity values of materials significantly. To help you
make ac curate comparisons of readings acquired un der varying conditions, the 6517B offers a built-
in type K thermo co
uple and an optional 6517-RH Relative Humidity Probe. A built-in 50,000 reading
data storage buffer allows recording and recalling measurements stamped with the time of the meas-
urement, the temperature, and the relative humidity.
