Re: Test equipment for valve radio repair
Mmmmm.Typical DMM is 10M input resistance. AVO8 on 500Vdc range is also 10M input resistance. Tricky call.
A serious bench DMM like the HP 34401A does have a hi z input (Gohms) selectable on its lower voltage ranges. Useful for measuring voltages across hundreds of Kohm resistors.
