Hi Ive been offered an Amprobe AM240, thumbs up or thumbs down, will this be a good stable mate for my Ideal 61-322 true RMS, which I trust from years of use, I have bought a couple of micky mouse meters, which will be on e/bay once I find another reliable meter , the AM240 is about the price I want to pay, as I have my eye on a Tektronix scope:)
