Tru Pointe® 2100 Instruction 0028-9003 1 About This Manual Thank you for investing in a Bacharach Tru Pointe® 2100 Ultrasonic Leak Detector. To assure operator safety and the proper use of the Tru Pointe® 2100, 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® 2100 Instruction 0028-9003 2 Introduction Congratulations on your purchase of the Bacharach Tru Pointe® 2100 Ultrasonic Inspection System. You have invested in the most sophisticated ultrasonic test instrument available. The Tru Pointe® 2100 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® 2100 Instruction 0028-9003 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® 2100 Instruction 0028-9003 Physical Description To begin using the Tru Pointe® 2100, first take a moment to become familiar with the unit’s controls. ON/OFF BAR GRAPH DISPLAY TOUCH PROBE SENSOR & SOLID PROBE 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® 2100 Instruction 0028-9003 4 Quick Start Guide Battery Installation The following instructions describe how to install/replace batteries in the Tru Pointe® 2100. 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® 2100 Instruction 0028-9003 the direction of the leak will cause the LEDs to drop below the Peak Hold level. Moving closer to the leak will cause Peak value to reset. The highest Peak value will indicate the strongest leak point. 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.
Tru Pointe® 2100 Instruction 0028-9003 5 Operation Using the Modes The Tru Pointe® 2100 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® 2100 Instruction 0028-9003 Setting the Sensitivity The Tru Pointe® 2100 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® 2100 Instruction 0028-9003 Airborne Applications The Airborne sensor is used to detect sound waves which travel to the Tru Pointe® 2100 through the air. The most common airborne application is compressed air or refrigerant leak detection. Leaks When searching for leaks with the Tru Pointe® 2100, 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® 2100 2. Instruction 0028-9003 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® 2100 Instruction 0028-9003 of condensate coming into trap as well. There are times when this is beneficial, and times when there is so much background noise that the Low setting may not be effective. The sound of most bearings comes alive in the Low range probe, however, very high speeds and/ or vibration sometimes make it necessary to use the High frequency probe. Your experiences with your equipment will determine which is the best setting for you.
Tru Pointe® 2100 Instruction 0028-9003 adjustment to eliminate any extraneous pipe noise and you will be able to hear only the internal flow of the valve. By using the readings on the display and your ear, you can determine which side of the valve is leaking. Bearings and Moving Machinery The most common mechanical failure is a broken or seized bearing. However this type of failure normally does not happen instantly. When the bearing begins to fail, the sound that it makes changes.
Tru Pointe® 2100 Instruction 0028-9003 Charting your results Ultrasound will be produced differently for all types of systems. It may be strong on one side of a bearing shaft, and weak on the other, depending upon the unique wear patterns. Therefore it is very important to mark the test point, so that future readings can be taken from the exact same position.
Tru Pointe® 2100 Instruction 0028-9003 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® 2100 detector.
Tru Pointe® 2100 6 Instruction 0028-9003 Principle of Operation The principle of operation of the Tru Pointe® 2100 is based on the turbulent flow of fluids and gasses. Turbulent flow has a high content of ultrasound, which the Tru Pointe® 2100 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® 2100 Instruction 0028-9003 5 Care and Service The Tru Pointe® 2100 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.
