Picoscope 6.14.23.5207

PicoScope 2204A

Hardware Version: 17

Driver Version: 3.0.40.2131

Create a math channel with the following equation: 60/((1/freq(A))*2) called RPM and a range of 0 to 1900. Don't enter a units long name or short name.

Select channel and click on OK to use it and PicoScope 6 crashes.

100% reproducible - happens every time.

## Crash When Using Math Channel

### Re: Crash When Using Math Channel

I would change the math channel

60/((1/freq(A))*2)

to

30*freq(A)

which is the same.

The reason you are getting the crash is that at the very start of the trace the frequency is unknown as there haven't been the crossing points to determine it, you will see no trace in the math channel plot. And if you ripple this through the math you get a divide by zero, which should fail gracefully so I will let the team know.

Once I added a name for the units (long and short) it went away. Andy
