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[...]

80 Series III Users M anual 14 Testing for Continuity Caution To avoid possible damage to the meter or to the equipment under test, disconnect circuit power and discharge all high-voltage capacitors before testing for continuity.
