12.2.3 “3-wire Voltage” Ampliers
Use the following wiring diagram when connecting an amplified
transducer or in-line amplifier with a 3-wire voltage amplifier to a
High-Level Input channel. Examples of such devices include
• transducerswithOption2corOption2tinternalampliers
(with shunt cal)
• ModelsUVorUV-10UniversalIn-Lineampliers(withshunt

The High-Level Input channel’s Configuration Jumpers must be
set as follows for proper operation. See “Excitation and Signal
Jumpers” on page 56.
