Silly question, probably. I have a cheap DSE multimeter, model Q-1420. Documentation's long gone, but I wanted to know its input impedance when measuring DCV. I'm setting the idle current on an amplifier and the service manual specifies a VTVM (tube voltmeter) to make the measurement
- presumably because of high input impedance. I assume if the DMM has
10 meg input impedance it'll be OK - but I need to know!Cheers, MK.
