BEST PRACTICES

- Check your parts. Upon receiving your scales, it is important to inspect the contents to make sure that all components are included and free from any physical damage that may have occurred during   shipping.

- Designate a lead. It’s best to designate one or two people responsible for installing and maintaining the scales. These individuals should become familiar with the installation process, the calibration process and the operation of the scale.

- Maintain your suspension system. Consistently accurate weight readings are dependent upon the operation of the vehicles suspension system and the condition of its components. Cleral scales are extremely precise, measuring air pressure on air ride suspension vehicles at .03 % of one psi; additionally, they compensate for temperature, altitude, humidity and barometric pressure. Suspension components including air bags and height control valves must be in good working order for the scales accuracy to be ensured. Repair any leaks and replace any HCV’s before calibrating the scales.  

When using Cleral’s mechanical sensors for spring ride and walking beam suspensions the vehicle’s suspension components must be in good working order (no broken springs, no cracked or severely underrated axles.)     

- Use quick response HCV control valves. Slow filling height control valves require that the driver waits longer for weight readings; Cleral recommends the following height control valves if the fill time is problematic, Ridewell Extreme Air or Hadley 500 series.

Cleral technology makes it possible to accurately acquire steer axle weight on semi- tractor trailer applications based on the percentage of weight transferred from the drive axles. This feature must be selected prior to calibration.

Certain Cleral systems have a feature (5th wheel slide) that will allow you to move the 5th wheel and still maintain an accurate steer axle weight reading.

If the tractor has a sensored steer axle, then you will not need to use either the Virtual Steer or 5th wheel slide features.

The following calibration tips will ensure you achieve the best possible accuracy with your Cleral scales:

- Use the same certified scale to obtain both your empty and your full weight data

- Enter empty weights when the truck is EMPTY

- Enter heavy weights when the truck is as close to the GVW as possible

 - You should be on level ground (whenever possible record the weights while sitting on the platform scale), with the brake off and the suspension in a neutral position (avoid coming to a hard stop)

- The fuel tank should be FULL

- If the vehicle is equipped with an automatic lift axle device, then you must acquire weights while the lift axle is engaged (down position) and the lift axle must be down when checking weights

- Manual lift axle(s) the lift axles should be in the up position during calibration and when checking weights

The following tips will ensure you achieve the best possible accuracy with your Cleral scales:

- Check weights only after you have come to a complete stop

- Always try to find level ground to check weights

- Come to an easy stop, tires straight, and the brake off if possible

- If you are using the Virtual Lift axle function you must activate the virtual lift axle channel before engaging the lift axle

- If you have a lift axle(s) and the scale was calibrated with the lift axles up, then the lift axle(s) must be up when checking weights. There are exceptions to this procedure if your vehicle has sensored lift axle(s) or the vehicle was calibrated with the lift axle(s) down

Using a personal identification number to protect your calibration data and settings is highly recommended. Protect the scale calibration by setting a PIN after calibration. 

After the PIN has been created, the PIN number must be entered directly into the scale to alter settings or calibration data. This prevents drivers from unintentionally changing settings that impact the accuracy of the scale.

If you have any sudden changes in accuracy and would like assistance, capture error code information from the scale prior to calling.
