Operation

The key for correct operation of the GDU-01-TT Ultrasonic Test Transmitter
is in the relationship between the ultrasonic transmitter and ultrasonic
detector.
Due to the nature of electronically emitted ultrasonic waves for optimal
performance, it is very important to have the transmitter aligned
perpendicular (±2.5 °) to the decibel sensing face. The closer the GDU-01-TT
is to the detector, the higher the detector's decibel output.
The GDU-01-TT has no adjustable controls and is set up to produce
approximately 106 dB at 1 meter in single operation mode.
CAUTION
The test transmitter is not intended to output a precise sound pressure
level (SPL).
Do not attempt to calibrate ultrasound detectors using this equipment.
