Resistance measurement has 6 different measuring signals
that can be applied to obtain a resistance measurement:
DC+, DC-, Pulse, PWM, Zero and Standby.
These 6 signals are described in below.
The Drive function is only applicable to the T3MIL50X and
the open circuit voltage is a maximum of no greater than
20mV when Drive function is activated. The Drive signal
for the T3MIL50 is fixed to DC+ and Standby.

This mode can be used to
eliminate the thermoelectric
EMF formed on the contact
t
between a test lead and a
DUT.
This mode can be used to
avoid heating up the DUT
and thus avoid having the
t
measurement accuracy
compromised on
temperature-sensitive DUTs.
The Standby is used to break
off Relay of Force+/-
without outputting test
t
current, and none of
measurements will be
executed.
