12. by using your ear When time passes between tests however it is very important to log your results because the slope of the curve that you will generate will predict the future failure of the bearing To take a reading on a mechanical system such as a bearing or gear box you must use the touch probe attachment Touch the end of the probe to the outer housing of the gear box or bearing making a good contact Do not press very hard at any given point when collecting data Use just enough force to keep the tip of the probe in place and try to be consistent with the amount of pressure you use It is often effective to use only the weight of the Tru Pointe 1100 itself to hold the tip in place Adjust the sensitivity so that the intensity meter reads 5 6 LEDs This gives you room on the display for future readings As the bearing wears the ultrasonic sound intensity will increase Future readings can indicate the extent of this wear When testing a bearing or other moving machinery it is important to 1 Record your volume sensitivity and frequency range 2 Record the level on the alphanumeric display 3 Record or mark the test point where the level was taken 4 Record the temperature using a thermometer By recording this Data you have the most accurate and repeatable test possible Although the sound of a moving machine member may fluctuate the Tru Pointe 1100 s built in peak hold feature will allow you to assign a number to the sou

22. traight long tube when the velocity of the fluid is not high A gas leaking out of a straight and long tube will not generate as much sound as if it were leaking out of a small crack because the flow is not turbulent The intensity of sound generated at a leak is a very complex function of the viscosity the tem perature the speed the fluid is moving the Reynolds number the pressure differential across the leak and the physical dimensions and characteristics of the orifice This is why it is impossible to quantify the size of a leak with ultrasonic technology A smaller leak may generate more sound than a larger one The Tru Pointe 1100 detects ultrasound NOT the presence of a specific gas It is NOT a gas Sniffer Because of this fact the Tru Pointe 1100 can function in areas where heavy wind or a concentration of fumes renders other detectors useless WARNING Ultrasonic detectors will not indicate a leak if there is no turbulent flow producing sound when checked If you suspect a toxic gas natural gas or other combustible gas leak and it is not detected by the Tru Pointe 1100 do not assume it doesn t exist and use another method as verification there is no gas leak present 15 Tru Pointe amp 1100 Instruction 0028 9002 5 Care and Service The Tru Pointe 1100 is constructed of durable impact resistant ABS however it is also a precision electronic test instrument which should be handled with care and respect We sugges
