Re: Maths is cool

Great post Steve. The voltage drop across a resistor is exactly the same way as an ECU uses to monitor current flow in a circuit. The 50 watt resistor is probably a bit over spec as you are not going to see 12.6 volts drop across it unless you short it across the battery. At 4 Amps it will be more l...

Thanks

David

Was hoping to just trigger when A+B was not at a set level.

How would you do this with logic trigger?

Steve Smith any ideas?

Feature request: Trigger from maths channel?

Hi, Is it possible to trigger from a maths channel? Today a colleague was looking for a fault on a CAN Bus system where one channel would intermittently drop out. He was hoping to be able to use single trigger to capture the event. Obviously you can set up a A+B maths channel that would basically sh...
