Hi Coen, feel free to send us an email at info@prismaelectronics.com — we’ll get back to you with two different procedures you can follow.
When you write to us, please explain a bit more about your setup: for example, do both karts run in the same track session? Do they use the same race number?
@stefano, the gauge does not measure the air temperature within the tire.
@collin, I’m sharing the link for replacing the battery:

If have two karts that I need to set pressures on, how can I set the starting pressures on both of the karts and then go back to the separate karts and record the hot pressures?
Hello, can you tell me how you change the battery of the HPM5 ?
is the gauge able to read the temp of the air inside the tyres once connected to the valve?

Hi Alexander,
To use the Vehicle Number feature, you need to activate it either through the APP or directly from the instrument’s menu.
In the instrument menu, look for the “Vehicle #” function and activate it by pressing the + button.
Once the function is activated, you will be able to enter the vehicle number at the beginning of each session.
How to Enter the Vehicle Number?
On the display, you will see “000”.
• Use the + and – buttons to increase or decrease the first digit.
• Press MEM to confirm the selection.
Thank you! 😊🚀
