Using a Digital Multimeter for the first time

After 15 years of service I replaced my old voltmeter with a Radio Shack Digital Multimeter.The instructions read that the amps should be turned off when inserting the leads. This would mean that after playing the amp for 2 hours I would have to turn them off insert the leads and then turn the amp back on.I doubt if I could get an accurate reading this way but Radio Shack says I could.So,I ask for your opinions.
Thanks all

You'll have to wait for the voltages to settle back down, if you are trying to measure your bias adjustments(regardless of how they are read). I use a Fluke digital and just push the 1/4" plug(Cary provided) into the jack with the meter turned on(no problem), but my Carys read out the bias as current(in mA).

Give the amp at least 30 minutes(after turning back on) to stabilize before taking your readings. How do your leads connect to the amp?

Mr O- In my previous post I was stating the method that works for my Cary amps, not suggesting you try the same. There are too many variations on the bias adjusting theme to make generalities. Glad you found a method that works without the smoke issue!
