ACES Z10-100-1015 – ProBalancer Sport Vibration Analyzer Balancer

The protective boot (75-900-1016) is not included with the handheld Model 1015 ProBalancer Sport unit, but we strongly recommend adding it when placing your order.

The Model 1015 ProBalancer Sport is designed for light aircraft with 100 HP engines or less.

The ProBalancer Sport Basic Kit includes:

• ProBalancer Sport Unit
• Vibration Sensor/Cable Combo
• Vibration Sensor Mounting Bracket
• PhotoTach
• PhotoTach Mounting Bracket
• Non-Skid Tape (for use with the PhotoTach mounting bracket)
• PhotoTach Cable
• Propeller Protractor/CD Combo
• 10 ft. (3.05 m) of Reflective Tape

The Model 1015 ProBalancer Sport is warranted against defects in material and workmanship for one (1) year from the date of purchase. The warranty does not cover the balancer unless it is properly used, stored, and maintained per the provisions in the User Manual.

Warranty replacement or repair will not be honored on any unit overdue for its annual calibration at the time of the warranty claim. If your calibration is overdue and no warranty claim is being made, you need only complete your overdue calibration to revalidate your warranty.

Yes. Your equipment comes calibrated and certified per NIST standards, effective the date of shipment. The balancer will be identified as calibrated by a sticker stating the calibration date and the next calibration due date.

A calibration certificate will be provided to you to verify compliance with inspectors. TEC, the parent company of ACES Systems, will also maintain a permanent record of your calibration.

Annual calibration is highly recommended unless you suspect the unit's performance. Other calibration intervals may be used based on standards established by your quality processes.

In addition, the vibration sensors should be calibrated annually or when dropped, damaged, or suspected of improper operation.

No. The Model 1015 ProBalancer Sport is only designed to perform propeller balancing. To accomplish a vibration survey, you will need a balancer designed for this purpose.

The ACES Systems Viper II and Cobra II balancers provide full-bandwidth vibration spectrum analysis. The Viper II also offers transient balance surveys to assist in locating and recording vibration surveys.

The typical cause for this situation is battery failure. Other scenarios could be (but are not limited to):

• The balancer was exposed to the elements for a prolonged period of time.
• The balancer experienced a large electrical power surge from an external source.
• The balancer was dropped repeatedly or from a height of more than three feet.
• A component in the balancer’s hardware has failed.

If you suspect any of the alternate scenarios, please contact us.

The Model 1015 ProBalancer Sport features return points within its software, allowing users to resume from a logical point after the balancer has been turned off or timed out.

Restart points are set at steps requiring user input or steps that don't involve data acquisition. If the balancer is turned off during a data acquisition step, it will restart at the most recent step that doesn't require data collection. Any data collected after that point will be lost and must be retaken.

If this was the first weight installation, then this is a normal condition. The first weight solution the balancer gives is a test weight. This weight is NOT intended to balance the propeller. It is intended to create a change in the vibration level of the propeller. The balancer learns from the changes incurred by the test weight and uses the information acquired to accurately calculate a balance solution.

If this was not the first weight installation, user error may have occurred. The balancer relies on accurate input from the user to calculate balance solutions correctly, which is crucial for its successful operation.

An inconsistent phase angle occurs when the phase angle cannot be repeated consistently, regardless of whether a known weight or no weight is installed on the propeller.

For instance, if you add 20 grams at 180° and the phase angle changes, you should input the same weight and angle into the balancer on the next run and check if the phase angle shifts to a completely different value. If so, this indicates an inconsistent phase angle; if the phase angle remains the same, it is not inconsistent.

Allow a tolerance of 10 to 15 degrees when evaluating the phase angle's consistency. Inconsistent phase angles are usually caused by either high winds or mechanical issues within the engine or propeller assembly.

Check the vibration sensor to ensure it is not being struck by cowlings or other engine components. Objects striking the sensor will generate false high vibration readings and could permanently damage it.

Even objects striking the cable near the vibration sensor could produce high vibration readings. Properly installing the vibration sensor and securing the cables will prevent this type of error.

If your balancer is not providing a vibration reading of any kind, you should:

• Check your cable connections to ensure the connectors are properly installed.
• Check your vibration sensor and cable for visible damage.
• Ensure your vibration sensor is properly installed and that the connector has the proper orientation.

If no discrepancies are found, you may have a damaged vibration sensor.

Yes! The Model 1015 ProBalancer Sport uses an IMI 608AII accelerometer, which is the only sensor it can recognize. This configuration is engineered to give you an economic balancer with the highest accuracy possible.

This is normal! The balancer uses the last weight added as a temporary adjustment to calculate the overall weight needed to correct the imbalance. This process is similar to calculating the center of gravity (CG) for an airframe: the farther the weight is placed from the propeller shaft, the less weight is required to achieve balance, and vice versa.

AC 43.13 provides guidelines for proper permanent weight placement. To calculate permanent weights manually, measure the spinner's diameter, divide by 2 to get the radius, and subtract the distance between the temporary and permanent weight locations from that radius. This gives you the arm for the permanent weight. Multiply the spinner’s radius by the total balancing weight, then divide the result by the permanent weight arm to determine the necessary weight for the permanent location.
