A time domain reflectometry measuring instrument uses a microprocessor that provides
added functionality and capabilities. The circuit electronics and probe are tested
and calibrated at the factory. Installation and commissioning by the user is simple.
The user installs the probe. The transmitter is attached to the probe. The user
connects a standard shielded twisted pair to the electronics. Power is applied
and the device immediately displays levels. A few simple parameters may need to
be entered such as output characteristics and the process material dielectric constant.
