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. Using patented signal processing, the Tru Pointe®provides the most precise
readings available.
The Tru Pointe®2100 can detect pressurized leaks of compressed air, refrigerant, steam, and
nitrogen, as well as detecting a vacuum leak. The Touch Probe allows the quick detection of flow
abnormalities in pumps, steam traps and valves, as well as mechanical wear in bearings and
other moving machine parts. Noise patterns can be recorded and compared to previous readings
for an accurate record of noise patterns.

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. Plug the headphones into the jack on the right side of the instrument
2. Press the On/Off Button once to turn the unit on.
3. Press the On/Off Button again to turn the unit off.
NOTE: If the unit is in “AIR” mode, translated ultrasound
can be heard immediately. If the unit is in “PrbH”, “PrbL”,
or “PrbS” mode, the Touch Probe must be in contact with
the item being tested to translate the ultrasound.
Airborne Leak Detection
Use the Airborne Sensor for detecting pressurized gas leaks, vacuum leaks, or when using the
SoundBlaster®. Leaks must be turbulent to be detected ultrasonically.
Using the Tru Pointe®2100:
1. Insert the headset plug into the jack on the side of the instrument.
2. Push the Power Button once.
3. Push the Mode Select Button until the alphanumeric display reads “AIR”, then
press ▲or ▼to activate it. Once activated, the current sensitivity setting (0 to
255) will be displayed and translated ultrasound will be heard. The Bar Graph
Display will display the strength of the corresponding signal. The highest LED will
hold its place for 5 seconds before resetting its position.
4. The instrument always resets itself so that sensitivity is the active mode. Pressing
the ▲or ▼buttons will adjust sensitivity up or down. If the LED Bar Graph Dis-
play is at maximum, reduce the sensitivity by pressing ▼until it reads “5” or less,
and continue searching for the leak. Pointing the Tru Pointe®2100 away from the
leak will cause the bar graph level to drop. Pointing the detector toward, or getting
closer to the leak, will cause the bar graph level to increase. Any deviation from

Tru Pointe® 2100 Instruction 0028-9003
6
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 alpha-
numeric 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. This sound will increase as the instrument is drawn toward the leak
point, and will clearly disappear as the sensor is turned away.
7. For more detailed information on specific applications, refer to page 9 of this
manual.
Touch Probe Applications
Use the touch probe to detect internally generated ultrasound such as leaks in steam traps,
valves, and sounds from bearings.
WARNING! To ensure a good contact and accurate
readings the touch probe has a sharp tip. Be careful not
to injure yourself or others.
1. Insert the metal Touch Probe into the port on the nose of the Tru Pointe®2100.
The Tru Pointe®2100 Touch Probe should be snug but do not overtighten. De-
press the mode select button until the display reads “PrbH”, “PrbL”, or PrbS” and
press the “▲”or “▼” to activate the touch probe selection.
2. Making a firm contact, touch the tip of the probe to the item being tested. Apply
just enough pressure to make good contact. A clear translation of the internally
generated ultrasonic sound will be heard.
3. Listen for fluid leaks in valves, continuous flow or non-cycling in steam traps, and
knocking or scraping in bearings.
4. The Tru Pointe®2100 always defaults back to Sensitivity as the active mode,
therefore if readings are off the scale simply press the “▼” to reduce the reading
to within the range of the instrument. The alphanumeric display will display the
active sensor and current sensitivity setting before it begins to make the adjust-
ments.
NOTE: When testing bearings or machinery vibration,
record your sensitivity setting, and use the reading
on the Alphanumeric display as a baseline for future
readings.
