Is there a way to manually set the graph scales on my android phone? i am reading dc amps of around 1 amp and it displays is on a 400 amp scale.

On my BT-570C-APP the DC current scales are 200A or 1000A. The AC current scales are 400A and 1000A. The stated accuracy of both the 200A DC and the 400A AC scales is 3% of reading plus or minus 10 digits. Both scales have a least significant digit of 0.1A, so the accuracy cannot exceed 0.1A x 10 = 1.0 amps. There is no way to improve the accuracy of such a low reading on a large scale. However, by wrapping multiple turns of wire around the jaw of the meter, you can increase the reading magnitude and improve the accuracy/resolution. Ten turns of wire will yield 10 amps instead of 1 amp flowing in the wire.. Simply divide the displayed meter reading by the number of turns of wire around the jaw. Thus you can effectively increase the accuracy and resolution of low readings.

Will this device measure 0.5-10 amps ac or dc? (as in hvac applications).

Yes, it can be tested. But there will be a little error. Its optimal measurement range is 200A and 1000A. It is more accurate in these two ranges.

How do you change temperature display to show degrees Fahrenheit instead of Celsius?

Sorry, the clamp meter is only Celsius and can't be switched to Fahrenheit temporarily. Celsius ranges from -20 to 1000 degrees. We have developed an upgraded version of this clamp meter, which will have degrees Celsius and Fahrenheit, so stay tuned, thank you.

You can find the QR code of the app on the main picture and electronic manual of the listing. And then, you can use the mobile phone to scan the application.I wish you a happy stay.
