3.3 FITTING THE TRANSDUCER
The transducer transmits and receives ultrasonic sound waves that the gauge uses
to calculate the thickness of the material being measured.
The transducer connects to the gauge via the attached cable, and single coaxial
connectors.
Transducers are supplied with two replaceable delay lines, 6.35 mm (1/4") and
12.7 mm (1/2"). The 12.7 mm (1/2") is suitable for most applications and measures
steel up to 25 mm. Generally, it should be used to measure thicker materials. It will
also dampen the signal of noisy materials, providing better accuracy.
The 6.35 mm (1/4") delay line provides more signal strength and may allow you to
measure tough-to-penetrate materials.
To change the delay line, unscrew the end of the transducer and apply couplant to
the connecting end of the delay line before screwing together.
3.4 SWITCHING ON/OFF
To switch on or off, press ON/OFF
.
The gauge will switch off automatically after 5 minutes of inactivity.
