3. Wiring
The terminal input module is connected to adjacent H and L terminals. When making 3-wire half
bridge measurements, the 3WHB10K performs two single-ended measurements. The sense wires
from the platinum resistance thermometer (PRT) attach to the 3WHB10K. The black excitation
wire is connected to an excitation terminal. In the following example, the 3WHB10K is connected
to the 1H and 1L terminals, using them for two single-ended measurements. The excitation wire is
connected to excitation terminal VX1 (
(p. 3)).
