Glossary	®

Ultrasonic Distance = Ultrasonic Measurement = Height-Above-Ground Measurement

The receiver’s height above the ground, which is displayed in the bottom window for 2 seconds after the trigger is clicked. The ultrasonic measurement is used to accommodate the different heights of drillers. For more information see “Ultrasonic Function” in the Receiver Section.

Ultrasonic Function

Determines the elevation the receiver is above a surface (up to a distance of 90 inches) and displays this “ultrasonic distance” in the bottom window of the receiver for 2 seconds any time the trigger is clicked (after the unit is powered up). The transmitter does not need to be active for operation of the ultrasonic function.

Ultrasonic Transducers

Sensors located in the two openings on the bottom of the receiver that measure the height of the receiver or the ultrasonic distance.

V AC

Volts alternating current.

V DC

Volts direct current.
