Making Measurements 13 The following are some tips for measuring voltage: • When you measure voltage, the meter actsapproximately like a 10 M Ω (10,000,000 Ω ) impedance in parallel with the circuit. This loadingeffect can cause measurement errors in high-impedance circuits. In most cases, the error...

80 Series IIIUsers Manual 14 Testing for Continuity Caution To avoid possible damage to the meter or tothe equipment under test, disconnect circuitpower and discharge all high-voltagecapacitors before testing for continuity.

80 Series IIIUsers Manual 18 Using Conductance for High Resistance orLeakage Tests Conductance, the inverse of resistance, is the ability of acircuit to pass current. High values of conductancecorrespond to low values of resistance. The unit of conductance is the Siemen (S). The meter’s40 nS range m...

Making Measurements 19 The meter measures capacitance by charging thecapacitor with a known current for a known period of time,measuring the resulting voltage, then calculating thecapacitance. The measurement takes about 1 second perrange. The capacitor charge can be up to 1.2 V. The meter’s capacit...
