Follow these steps while weighing your vehicle:

Park on a level surface. Shift the transmission to neutral and set the parking brakes.
Chock the wheels to prevent unexpected vehicle movement, then release the parking and service brakes.
Make sure the Height Control Valve (HCV) has fully inﬂated the air bags. If needed, brieﬂy dump the air from the suspension and allow the HCV to reﬁll the system. (This may take several minutes depending on the type of HCV.)
Press the ON/OFF button to turn on the Right Weigh load scale.
Adjust the suspension or the load itself until the Right Weigh load scale displays a weight value below your legal limit.
Press the blue MENU button to display other axle groups or calibration sets.
Press the ON/OFF button to turn oﬀ the Right Weigh load scale.

The gauge may be connected to power via the vehicles marker lights, or the AUX/ABS power wire. If your lights provide power to the gauge, be sure that the lights are turned on when you want to connect and take a weight reading.

MOBILE DEVICE CONNECTION

To comply with Transport Certiﬁcation Australia (TCA) requirements and to view total vehicle weight, it is required to use a smart phone or tablet with a mobile app to wirelessly connect to all scales or Mass Sensor Units (MSU’s) on the vehicle. More than one app is available and you must choose the correct app based on your speciﬁc use case. Below are the available options:
RIGHT WEIGH LOAD SCALE APP
Use the Right Weigh Load Scale App if your use case is one of the following:

A ) You are not required to have a TCA compliant OBM system
B ) You are required to have a TCA Category A Type-Approved OBM system For more information on the Right Weigh Load Scale App, refer to page 7.

V-DAQ APP
Use the V-DAQ APP if you are required to have a TCA Category B Type-Approved OBM system. To be compliant with the Category B requirements, you must also have an approved V-DAQ telematics device installed on the vehicle’s prime mover. For more information on V-DAQ telematics and associated mobile app, refer to page 13.

Go to the Google Play or App Store and download the Right Weigh App!

TCA OBM Requirement:
To comply with TCA requirements, a special app MUST always be used
and setup properly to view vehicle weight. For Category B applications, this app must also be connected to a TCA approved telematics partner on the smart device anytime the vehicle is in use. Because the available options and requirements change periodically, please scan the code or visit this web page to get the most up-to-date information, links to the appropriate applications, and hardware. For more information on TCA requirements, refer to pages 7-8.

Once the Right Weigh Load Scale app has been downloaded onto your smart device, follow these steps to connect to your scale.

With the gauge oﬀ, hold down the MENU button, press the ON/OFF button, and release both simultaneously.
Press the MENU button twice to see the unique identiﬁer. This identiﬁer will appear in the factory-set scale name and the scale ID (MSU ID) displayed in the app.
Once the app has been downloaded and opened, you will see the home screen with no gauge connected to it and a gross weight of “0”.The Bluetooth connection range is between 100 to 250 feet or more, depending on the device brand and version, line of sight to the scale, and material interferences. A direct line-of-sight with no metal or concrete interference will provide the best possible signal. Metal or concrete obstructions will reduce the signal strength. Signal strength further degrades as more or thicker obstructions are added between the smart device and the load scale.
On the app home screen, press the “Add Gauge” button and choose whether the gauge is connected to the truck or trailer. If you are adding more than one gauge, be sure to add the truck gauge ﬁrst and then add the trailer gauges in order from front to back.
Look for the gauge with the name containing the unique identiﬁer found in step 2. Select the appropriate gauge to add it to the home screen. When connecting to more than one scale, the scales should be added in front to back order of how they appear on the vehicle. See Appendix C for more information.

V-DAQ TELEMATICS DEVICES

If your vehicle is equipped with a V-DAQ telematics device, the V-DAQ mobile app must be used in order to connect to the Right Weigh system. The app will connect to
each Right Weigh gauge via Bluetooth to collect mass data and manage the vehicle conﬁguration. Download and install the V-DAQ app from Google Play or the App Store. Contact V-DAQ for information on the app and connecting to the OBM system.
TCA OBM Requirement (Category B only):
The prime mover must have an approved telematics device installed and the device must be connected to the Right Weigh system.
Warning:
The V-DAQ mobile app takes the place of the Right Weigh app for applications needing to connect to V-DAQ telematics. Do NOT install both apps.

GENERAL APP INFORMATION

Be sure to add the scales on the app in the correct order (front to back). RW
201 Series Exterior Digital Onbaord L 12 If the trailer scales are in the wrong order, delete them and re-add them in the correct order.
The app can support up to 8 scales at a time. Signal strength is best when the phone has a direct line-of-sight to the scales. Metal obstructions will reduce the Bluetooth range of the system. Make sure that all scales are connected before taking a weight reading. In some cases, it may be necessary to step out of the vehicle to connect to
scales that are far away.
Scales can only be connected to one device at a time. If other drivers near by need to connect to the scale, make sure to delete it oﬀ the app so that it can be discoverable to other devices. (Delete scales by pressing the “Details” button and selecting the delete scale icon at the top right of the screen. See page 11 for more information.)

If the app shows an improper Bluetooth connection on any of the scales, DO NOT use the weight reading. Verify that all gauges are connected before taking a weight reading.

Follow these steps to regain Bluetooth connection: RW 201 Series Exterior
Digital Onbaord L 13 Make sure you are within range of the scale and that there is nothing interfering that may block connection. Make sure the scale is receiving power (if the scale doesn’t turn on, check that it is connected to a SWITCHED power source). If another user is connected to the scale, have them delete it oﬀ of their app in order for you to connect to it. Delete the scale from the app and try re-connecting to it.

TROUBLESHOOTING GUIDE

PROBLEM	CAUSE	SOLUTION
Erratic / Inaccurate Weight Readings	The vehicle is not parked on a level
surface	Park on level concrete ground. Parking on sloped or banked surfaces

will cause the vehicle weight distribution to shift between the axle groups. Additionally, if one or more of the vehicle’s wheels are in a pothole, that could result in additional pressure or torque on the suspension air bags. This will cause the suspension to have a diﬀerent air pressure than what is normally needed to hold up the given weight.
The vehicle’s brakes are on| Release the parking brakes when weighing and/or calibrating. When the vehicle brakes are set, they could apply additional pressure or torque on the suspension air bags. This will cause the suspension to have a diﬀerent air pressure than what is normally needed to hold up the given weight.
There is a signiﬁcant air leak in the suspension system| Check air lines for leaks. Having a leak could cause the HCV to

reﬁll the suspension at regular intervals to maintain the vehicle’s ride height. If there is a signiﬁcant leak, the gauge display will slowly decrease in value and then quickly increase in value when the HCV reﬁlls the suspension system.

The Height Control Valve (HCV) is malfunctioning or broken| If the HCV is not functioning correctly, the air pressure applied to the suspension system could be inconsistent and/or erratic. To test for an HCV problem, acquire a weight reading from the Right Weigh gauge and write it down (refer to gauge operating instructions for proper procedure). Drive the vehicle around the block and return to the same location. Acquire a second reading from the Right Weigh gauge. If the two readings are signiﬁcantly diﬀerent, then the HCV might be malfunctioning.
Scale Does Not Power On| Marker lights have not been turned on| The scale may be connected to the marker lights. These need to be turned on for the scale to turn on.
App Won’t Connect to Gauge| Phone needs to be reset| To reset your phone – close the app, turn oﬀ Bluetooth, and wait 10 seconds. Then, open the app and turn the Bluetooth back on. Try rescanning for the scale. If this still doesn’t work, in some cases it is necessary to restart the phone completely.
Scale is already connected to another device| Have the other user remove the scale from their app. The scale can only connect to one device at a time.
