JUST BOUGHT A 1/2 TORQUE WRENCH. HOW TO MAKE SURE IT'S ACCURATE ?

So what the title says. I just bought a new torque wrench and apparently it was made in 2019.

The seller says that it was calibrated more than once before it got to me but i just want to make sure its accurate because i will be using it on my bike and i need to make sure. How can i ?
