GND Terminal
GND
Connect the GND (ground) terminal to
the earth ground.
GUARD Terminal
GUARD
The GUARD terminal has the same
potential as earth, but cannot be
substituted for it. Connect the GUARD
terminal to the cable shield layer of the
test leads to help reduce noise.
Function Keys
Ohm
The Ohm key activates the resistance
measurement function.
Compare
The Compare key activates the
comparator function.
Binning
The Binning key activates the binning
function to grade the DUTs into eight
bins according to the tolerance settings.
GOM-805 only.
TC
The TC key activates the TC
(temperature compensation) function
which calculates the resistance of a
DUT at a specified temperature given
the resistance of the DUT at the
ambient temperature and the
temperature coefficient of the DUT is
known.
TCONV
The TCONV (Temperature
Conversion) function calculates the
temperature of a DUT given an initial
temperature, initial resistance, measured
resistance and a constant (inferred zero
resistance temperature) for the DUT.
TEMP
The TEMP key activates the
temperature measurement function.
