There are several PDF documents for the Ultrix 100 located at its main page or at the "technical" page.
The
Ultrix 100 is unique! It can be suspended by its signal cable.

BEAM
ANGLE and BEAM SHADOW
The ultrasonic sound wave spreads out like a cone from the sensor. The bigger the cone angle or the farther the distance to the target, the greater the influence from nearby objects. The Ultrix 100 sensors have a narrow beam angle from 7 to 11 degrees. The Beam Shadow is the width of the beam at any point in its travel - a fixed object (such as a ladder) projecting into the beam's path may prevent measurement.
OFFSET / ZERO and SPAN
The Ultrix 100 may be set to transmit 4-20 mA over any range within its overall available range. The Zero (offset) is the level at which the Ultrix transmits 4 mA. The Span is the level at which the Ultrix transmits 20 mA.

To calibrate the 4 mA output, hold the transmitter at the proper distance for the 4mA level and touch the magnetic key against the “Z” (zero) calibration icon. LED2 and LED1 both switch ON green. Keep the transmitter steady and aimed at the level/target until the calibration routine is finished and LED1 turns OFF. The transmitter automatically returns to the measuring mode.
To set the 20 mA output, repeat the above procedure using the calibration icon “S” (span). Aim the transmitter towards the target surface when its at the 20 mA level and touch the magnetic key to the “S” icon.
