What kind of battery does this use? Is it internal and rechargeable or do you place the batteries inside and if so, what size / type battery? Thanks

I am sorry for the delay in my answer. This device uses regular 9v battery (comes with it). You can use any rechargeable 9v battery. But, before you buy this device, I need to let you know that I find it to be no so accurate. The numbers keep jumping up and down, in high values, making the device useless. It has a way to lock on the max value, but does not show the real time number. I am going to send the supplier an email asking them if this is expected. I used to have an analog one, and it showed some small/ minute variation in readings, but still manageable. I bought this digital device, because I thought I can get a better, accurate reading. This might be more detail than expected, but hope it is useful.

Does this emit any kind of rf itself? i am highly sensitive to wi-fi radiation. it effects my heart condition. so can't have anything that emits it

Hello,The RF Meter is only measure the RF signals. It does not emits RF.

Will this meter measure the frequency from a high voltage power line running in front of our land? Need to know how far to build for it to be safe.

Hello, The HF-B3G won't measure low frequency EMF. In order to do so we recommend you using the MG-300 or the MG-2000T. https://www.amazon.com/dp/B01CGVBP5O https://www.amazon.com/dp/B01HQBRZ9O

Why are reading alot higher when held in my hand versus setting on table (ball not touching anything)? also why read higher on Y axis?

Hello, The reason for higher reading might be that your body serves as an antenna or a reflector of the signal back to the meter. Please ensure that your cell phone turned off when you do the measurements.
