As mentioned by Kris to use this unit ARVX4200W for your safety testing usage.
I have no issue to let you take it.
But please be reminded that this unit is not a mess production unit where the final tuning is not 100% done. Also, there’s no user manual inside the box.
Please confirm if you can use it. If so, you may download the Product Spec Sheet/Starter Guide/User Manual from here.
