Resistance connections
Two-pole resistance connections
The following figure shows typical 2-pole resistor test connections. The 2-pole resistance
configuration can be used to test up to seven devices under test (DUTs).
Channels 5 and 10 should not be used to switch resistance measurements because of the high path
resistance (approximately 240 Ω) of these two channels due to the factory-installed, current-limiting
resistors.
