Capacitance and Inductance Measurements
NOTE: An external AC power source is required to make
capacitance and inductance measurements.
1.
Set up the MODEL V-20 and the external power source as shown in figure 2.
WARNING:
Make certain the external power source is off before connecting the capacitance or inductance to be measured.
2. For capacitance readings of .009 MF to 1MF or for inductance readings, set the DC-AC-OUTPUT switch to AC
and the RANGE switch to 10V, and (with the meter leads connected across the secondary of the power transformer)
adjust the external power source for a full-scale reading of 10 volts rms. For capacitance readings of .0001 MF to. 03
MF, set the RANGE switch to 250V, and adjust the external power source for a full-scale reading of 250 volts rms.
CAUTION: Adjust the external power source starting from its lowest voltage so as not to overload the meter on the
selected scale.
3. With the capacitance or inductance in series with the secondary of the power transformer, as shown in figure
2,
read the voltage on the meter; then refer to table 1 (capacitance of .009 MF to IMF), table 2 (capacitance of. 0001 MF
to .03 MF), or table 3 (inductance of 5H to 1000H) to ob/n t-the corresponding value of capacitance or inductance.
