field indicates actual measurement voltage monitored by the meter, which shows 1V is applied to
the sample.

field shows a capacitance of a 10
F product, which is about 9.86
F which is within the
specified tolerance.

Note 2: Check Method of Measurement Voltage Applied to Capacitor Under Test
One method to check the measurement voltage actually applied to a capacitor under test is
to apply plus and minus probes of the tester to both terminals respectively of the capacitor set
into measurement jig, and read the indicated voltage.
A photograph in which
“
measurement voltage
”
of Fig.17 above is checked is shown in
Fig.10. It shows it indicates a value of 998mVrms.
Also, a photograph in which the
“
measurement voltage
”
of Fig.19 is checked is shown in
Fig.21. It shows the tester indicating 187mVrms and low capacitance due to the AC
measurement voltage being less than 1Vrms.
