Making M easurements 13 The following are some tips for measuring voltage: • When you meas ure voltage, the meter acts approximately like a 10 M Ω (10,000,000 Ω ) impedance in parallel with the c ircuit. This loading effect can c ause measurement errors in high- impedance c ircuits. In mos t cases, the error is negligible (0.1% or less) if th ...
