OVERVIEW

The STEELMAN PRO ™ Wireless ChassisEAR2 ® is a versatile noise, vibration, and harshness (NVH) diagnostic tool. The STEELMAN PRO ™ Wireless ChassisEAR2 ® Digital Control Unit receives NVH sounds from up to six transmitters that are connected to precision piezo microphones embedded inside of the included sensor clamps.  these clamps can be attached to almost any location on a vehicle that is experiencing elusive NVH to amplify sounds and aid in locating NVH. The unit can be used on a  vehicle either while parked or during a road test.
Some examples of areas where NVH originates and this unit can be used are:

• Wheel Bearings
• Brake Calipers
• C.V. Joints
• Leaf and Coil Springs
• Differentials
• Transmissions
• Body Mount Points
• Interior Trim
• Fuel Injectors
• Alternators
• Water Pumps
• Power Steering Pumps
• AC Compressors
• Accessory Pulleys
• Motor Mounts
• Engine Bay

Please read carefully the following instructions to ensure optimum use of the product.

MAIN COMPONENTS

COMPONENT DESCRIPTION

CHARGING

1.) To charge the Control Unit, use the included micro USB/USB cable. Plug the small end into the micro USB port on the left side of the Control Unit. Plug the large end into a USB/ DC converter (not included) or into a USB charging receptacle. An LED on the power button will illuminate the RED while the Control Unit is charging. The LED will illuminate GREEN when charging is complete.
2.) To charge the Transmitters, plug the Charging Station into an AC power source. Insert each transmitter into an available slot on the Charging Station. The Transmitter status  LED will illuminate RED while the unit is charging. When charging is complete, the LED will illuminate GREEN and then slowly fade to OFF.

DIAGNOSTIC USE

CAUTION:
It is illegal in many jurisdictions to operate a motor vehicle while wearing headphones. It is strongly recommended that any road testing be conducted with a dedicated driver  AND a technician.
1.) Power on the Control Unit by pressing the power button once.
2.) Power on each Transmitter by plugging them into the Sensor Clamp. The status LED will illuminate BLUE indicating that the Transmitter is powered and active.
3.) Place the Transmitters in each location that you wish to examine for NVH.
4.) In confined spaces, the Transmitter Jumper can be used to locate the clamp and
Transmitter separately. Plug the male end of the jumper into the Sensor Clamp. Plug the Transmitter into the female end of the jumper.
5.) Secure Transmitters using included Velcro and nylon ties to ensure they are not lost during road testing.
6.) When charging the product. the transmitter needs to be placed in the charging base. and the wireless function cannot be used normally. You need to wait until the charging is complete before you can use the wireless function.

MAIN SCREEN

The Main Screen is the landing screen when Wireless ChassisEAR2®is powered on. The use and functions of the main screen are described below:

1.) To select a channel to listen to, tap on the desired channel number button. If the bar on top of the channel number button is green, the channel is active and the transmitted sounds are being played back. If the bar on top is red, the channel is inactive. The location label below the button can be set from the “Location Settings” screen. The vertical color boxes on the right side of the channel button correspond with the boot color on the Transmitters.

2.) The volume buttons control volume output from the control unit. Tap “-” to decrease the volume and “+” to increase the volume. The sound from each Transmitter can be played back through the integrated rear speaker or through the included Headphones by plugging the headphones into the headphone port on the right side of the control unit.

3.) The NVH Level Meter shows the signal (noise) level of the selected channel being transmitted to the Wireless ChassisEAR2 ® receiver. The color of the meter will change between green, yellow, and red based on the level of the noise received with green being the lowest level and red being the highest.

4.) The Batt Meter shows the current Control Unit battery level. The meter will change to YELLOW when charging is needed soon and RED when battery depletion is imminent. The continuous run-time of the control unit is approximately 3.5 hours.
5.) The hamburger menu button will open the “Location Settings” screen where the location for each Transmitter can be input. Additional settings and functions can be accessed from this screen.

LOCATION SETTINGS SCREEN

1.) To edit Transmitter location information, tap the location text box under the channel location you wish to edit. A digital keyboard will be displayed, allowing the user to type the Transmitter’s location. Press “ENTER” to return to the Location Settings screen.

2.) The “Clear” button clears any locations previously entered and automatically returns to the Main Screen.
3.) The “X” button saves all changes and returns to the Main Screen.
4.) The “System Settings” button displays the System Settings screen.

SYSTEM SETTINGS SCREEN

1.) The “Signal Sampling Rate” box allows the user to select the speed at which the wireless ChassisEAR2®samples the signal strength. Default is “Fast”. A slower rate will
slow the speed at which the signal strength bar graph moves in real-time.
2.) The “Measurement Type” box allows the user to display the Peak Signal Strength
measurement or Average Signal strength next to each channel on the Main Screen. The peak signal strength setting will capture and hold the highest signal level from each channel while it is active. Average signal strength will capture the average signal level from each channel while it is active and then hold that value when another channel is selected. The default setting is “Measurement Off”.
3.) “The Default Settings” button restores all settings to their default values and returns to the Main Screen.
4.) The “X” button saves all changes and returns to the Main Screen.

5. The Peak or AVG measurement appears next to every channel when selected on the setting screen.
6. The Clear button resets all measurements to 0% to begin the test again.

TRANSMITTER CHANNEL ADJUSTMENT

Wireless ChassisEAR2® has six dedicated frequencies for receiving NVH noises that correspond to a dedicated channel on the receiver. Four pre-set Transmitters are included and up to 2 more channels can be added. The Transmitter channel can be adjusted using the dipswitches, located behind the TPR plug on each Transmitter unit. When adding additional Transmitters or replacing old ones, the channel will need to be set before first use Please see the diagram below for the dipswitch setting for each channel.
