Components 

 

Metered pistol housing

 

The main component of the Ultraprobe is its' pistol housing. From back to front, let's examine each 
part.

 

 

Bargraph Display 

 The display consists of a ten segment LED bargraph that will indicate ultrasonic signal strength. A low 
number  of  LEDs  indicate  a  low  level  of  ultrasound,  conversely  more  intense  ultrasonic  signals  will 
display more LEDs.  
 

 

Battery Level Light 

This red light turns on only when the batteries need to be replaced.  

 

NOTE:

 When the trigger on/off switch is pulled to the on position the Battery Level Light will flicker  

on and then stay off. This is normal and has no relation to battery condition.

 

 

Sensitivity Selection Dial 

There are eight (8) sensitivity levels which read out in related decibels of "0" to "70". As the dial is 
turned to the right, to "0", the sensitivity of the instrument increases. As the dial is turned to the left,  

 

to "70", the sensitivity decreases. A low level ultrasound emission produces low amplitude. For this 
reason, the instrument should be in a high sensitivity position. 0 is the high sensitivity position. 0 is  a 
dB indication of threshold detection for the instrument. For higher amplitude signals, move the 
sensitivity to the left towards "70". The dial dB indications, along with the LED indications in the bar 
graph may be used to establish dB levels. To do this, just add 3 dB for each LED bargraph indication 
to the dB level set in the sensitivity dial. EX: 0 dB on the sensitivity dial, plus 3 LED bargrah levels = 
9dB (0+9). 40 dB on the sensitivity dial plus 4 bar graphs = 52 dB (40+12)  
 

Head Set Jack 

This is where you plug in the headset. Be sure to plug it in firmly until it clicks. Should a tape recorder 
be utilized, this is where the cord for the tape recorder is inserted. (Use a miniphone plug). 
  

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; to turn the instrument off, release the trigger.
