An oldER VOM still can be high impedance. See what it lists (often written on the case), and multiply by your range where you measuring (say 10k/V at the range of 500V will make it 5M that does not load the circuit much, whereas A totally old one with 1K/V at the range of 500V makes it 500K and this might load it it enough).
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
