Tru Pointe® 1100 Instruction 0028-9002 1 About This Manual Thank you for investing in a Bacharach Tru Pointe® 1100 Ultrasonic Leak Detector. To assure operator safety and the proper use of the Tru Pointe® 1100, please read the contents of this manual, which provides important information on the operation and maintenance of the detector. Warning Statements The use of the word WARNING (and the warning symbol at left) in this manual denotes a potential hazard associated with the use of this equipment.
Tru Pointe® 1100 Instruction 0028-9002 2 Introduction Congratulations on your purchase of the Bacharach Tru Pointe® 1100 Ultrasonic Inspection System. You have invested in the most sophisticated ultrasonic test instrument available. The Tru Pointe® 1100 is the first ultrasonic leak detector to feature digital controls and displays, and no other ultrasonic detector can produce such accurate readings and consistent results in repeated tests.
Tru Pointe® 1100 Instruction 0028-9002 3 Specifications Physical Dimensions 7.075”L X 2.4”W X .875”D (197.7 mm X 61 mm X 22.22 mm) Overall Length 8.185” (207.8 mm) Body Material Aluminium and ABS Body Finish Anodized, Gold, and Black ABS Connector 3.5 mm Stereo Weight 0.5 lb.
Tru Pointe® 1100 Instruction 0028-9002 Physical Description To begin using the Tru Pointe® 1100, first take a moment to become familiar with the unit’s controls. ON/OFF BAR GRAPH DISPLAY TOUCH PROBE SENSOR (INTERNAL) AIRBORNE SENSOR & FOCUSING CONE HEADSET JACK (SIDE) 4 UP/DOWN & SELECT MODE SELECTOR ALPHA-NUMERIC DISPLAY Airborne Sensor Detects external ultrasonic sound traveling through the air, such as pressurized gas leaks, vacuum leaks, external system noise and the SoundBlaster®.
Tru Pointe® 1100 Instruction 0028-9002 4 Quick Start Guide Battery Installation The following instructions describe how to install/replace batteries in the Tru Pointe® 1100. 1. Turn the unit over so the controls are facing the floor. 2. Apply minimal pressure to the battery compartment panel and slide it toward the bottom of the instrument. 3. Install/Replace a 9v battery, noting the (+) and (-) positions on the inner label. Turning the Instrument On/Off 1.
Tru Pointe® 1100 Instruction 0028-9002 5. To adjust the volume, press the MODE button once. The alphanumeric display reads “VOL”. Then use the ▲ and ▼ buttons to make the adjustment. The alphanumeric display will display the current setting as V###. The volume reading has a range of 0 to 255. 6. Listen for the leak. A gas or air leak will sound like a harsh rushing noise, or high intensity hiss.
Tru Pointe® 1100 Instruction 0028-9002 5 Operation Using the Modes The Tru Pointe® 1100 uses a circular menu method of selection and adjustment. 1. Press the Mode Select Button to select the parameter to change. 2. Use the Up/Down arrows to make the adjustment or selection. 3. See Figure 1 for a list of the views in order.
Tru Pointe® 1100 Instruction 0028-9002 Setting the Sensitivity The Tru Pointe® 1100 always defaults to Sensitivity as the active mode. After any adjustment has been made, it will store the setting in memory, and reset itself so that ▲ and ▼ adjust sensitivity. Pressing the ▲ and ▼ arrows will adjust the sensitivity while in either sensor mode. The prefix on the alphanumeric display indicates the sensor being changed.
Tru Pointe® 1100 Instruction 0028-9002 Airborne Applications The Airborne sensor is used to detect sound waves which travel to the Tru Pointe® 1100 through the air. The most common airborne application is compressed air or refrigerant leak detection. Leaks When searching for leaks with the Tru Pointe® 1100, remember that you are listening for the turbulent flow of the gas as it flows from the leak orifice (refer to “Principles of Operation” on page 15 for a more detailed explanation).
Tru Pointe® 1100 2. Instruction 0028-9002 Reducing the sensitivity will suppress the effect background noise has on the display, and also in the headset. This will help make the leak sound more identifiable. Sometimes the most interfering background sounds come from areas of high turbulence within a pipe. This can be where high velocity flow changes direction, or is restricted such as within a partially closed valve.
Tru Pointe® 1100 Instruction 0028-9002 NOTE: It is fairly common for large manufacturing and processing plants to spend tens of thousands of dollars on steam system conservation programs (equipment and personnel) designed to locate and repair failing steam traps. Ultrasonic detectors play an important role in these programs. To test steam traps you will use the touch probe sensor. Press the “MODE” button until the display reads the desired probe mode, then press ▲ and ▼ to activate the touch probe sensor.
Tru Pointe® 1100 Instruction 0028-9002 Bearings... The First Test The first test is very important. This is the reading that all future tests will be based on. With some experience you will be able to compare two similar bearings and identify the sound of a good bearing from a worn one just 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.
Tru Pointe® 1100 Instruction 0028-9002 Vibration Vibration, misalignment, or moving machinery which is not properly balanced can be deadly to a system. These things can cause excessive wear bringing the life of any system to an early demise. All these problems have a common warning signal; increased ultrasonic energy. This ultrasonic energy is generated from the friction associated with these problems, and can be detected with the Tru Pointe® 1100.
Tru Pointe® 1100 Instruction 0028-9002 SoundBlaster® Sound Generator The SoundBlaster® ultrasonic sound generator is used to detect leaks in enclosures which are not under pressure. This item can be placed inside a vessel such as tank or walk-in freezer compartment. The sound generator emits a powerful 115dB ultrasonic tone which will follow the empty passage a gas or liquid would travel to produce a leak. The tone can then be identified at the point of exit by using the Tru Pointe® 1100 detector.
Tru Pointe® 1100 6 Instruction 0028-9002 Principles of Operation The principle of operation of the Tru Pointe® 1100 is based on the turbulent flow of fluids and gasses. Turbulent flow has a high content of ultrasound, which the Tru Pointe® 1100 can detect. Imagine air leaking from a tire. Because this is such a large leak, your ear can detect this sound, however your ear hears only about 1/3 of the actual spectrum of sound which exists.
Tru Pointe® 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 suggest you follow these simple instructions to insure many years of reliable performance. 1.
