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
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 amplifiers (with shunt cal)
•
Models UV or UV-10 Universal In-Line 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.
