12.2.4 “3-wire Voltage”
Amplifiers with Single-wire
Shunt Cal
Use the following wiring diagram when connecting an amplified transducer with a
3-wire voltage amplifier with single-wire shunt calibration to a High-Level Input
channel. An example of a such device includes
3-wire voltage amplifier with single-wire shunt calibration to a High-Level Input
channel. An example of a such device includes
•
transducers with Option 2d or Option 2g internal amplifiers (with shunt cal)
The High-Level Input channel’s Configuration Jumpers must be set as follows for
proper operation. See “Excitation and Signal Jumpers” on page 106.
