TRIGGER SWITCH.
This is located on the underside of the
Ultraprobe 100. The Ultraprobe is always “off” until the trigger switch is
pressed. To operate, simply press the trigger and hold; to turn the
instrument off, release the trigger.
SCANNING MODULE
This module is utilized to receive air-borne ultrasound such as the ultrasounds
emitted by pressure leaks and electrical discharges. To use, make sure it is
plugged in to the front end of the metered pistol housing by aligning the plug
with the receptacle and inserting it firmly. It has approximately a 60° field of
reception.
TO USE THE SCANNING MODULE
Plug in to front end
Start with the sensitivity selection dial at maximum (0)
Start to scan the test area
The method of air borne detection is to go
from the “gross to the fine”. If there is too much ultrasound
in the area, reduce the sensitivity, place the RUBBER FOCUSING PROBE (described below) over the
scanning module and proceed to follow the test sound to its’ loudest point. If it is difficult to locate the
sound due to a high intensity signal, keep reducing the sensitivity and following the meter to the loudest
point.
CONTACT (STETHOSCOPE) MODULE
This is the module with the metal rod. This rod is utilized as a “wave guide” that
is sensitive to ultrasound generated internally such as with a pipe, bearing housing, steam
trap or wall. Once stimulated by ultrasound, it transfers the signal to a piezoelectric
transducer located directly in the module housing.
TO USE THE STETHOSCOPE MODULE
Align the pin located at the rear of the module with the jack in the front end of the
Metered Pistol Housing and plug in firmly.
Touch test area.
As with the scanning module, go from the “gross” to the “fine.” Start a maximum sensitivity on the
Sensitivity Selection Dial and proceed to reduce the sensitivity until a satisfactory sound and meter
level are achieved.
