has been damaged. Here are a few things I couldn't find online or in other reviews. I have a desktop power supply and an electronic load, so I was able to test the amp clamp at low values (like a parasitic drain). Really low readings like 30-40mA can be obtained, but they are not very accurate. A current between 30-40mA always shows 20mA, but it is still better than a value of 0. From 50mA the meter worked accurately. It is important to check the zero point regularly as I have found that after a while it will drift and distort the reading. The meter measures AC Hz. Strangely, the meter does not measure Hz voltage through the probes. It's a little strange, but enough for me.
