My workshop radio ham shack is expanding , the latest piece is the Farnell TM2 it measures from 1 Mv to 300v, took it to friends who do proffesional calibrations, and it didn't need calibrating on any range, it's got to be and old piece of kit, I was advise that before using in the cold days I should let it sit there switched on for around 15 minutes in the house, spot on piece of gear
))), think I'm going to back light the meter, as I'm doing with all my gear. Tarty gear.
