I recently bought a CT-2 ammeter, and I'm having an issue with it. I've written an application in Python to pull data from the ammeter, and it is working great. But even though I'm hitting the ammeter at about 40 Hz, I'm only getting new values about every 250ms.
You can see that in this image, which shows a dot for each reading:
I can see while running the on-screen graphical real time display, that it can run at up to 100Hz. Is there some command I can send to the ammeter, or a mode I can put it in manually, to get real time data?
