Problem with new multimeter

Post by ckmcwill »

Hi all,

I recently purchased the multimeter from adafruit and have been unable to get any current readings from it, aside from the 10 A setting. I cannot read anything in the mA settings. I'm rather new to this sort of thing but have read the directions. My circuit is supposed to be providing about 20 mA. I can get it to read 0.02 A on the 10 A setting, but I can't get any readings on any of the lower settings. Can you suggest soemthing that I might be doing wrong?
By the way, I have had no problems with the voltage or resistance readings.

Thanks!

The low-current measuring circuits are fused @200mA. If you try to measure anything higher than that the fuse will blow to protect the meter. It is a standard size fuse and easy to replace.
