• The capacitance measurement is automatically taken after the insulation resistance
measurement ends.
• The capacitance measurement is not performed if the output voltage is 250 V or less during
the insulation resistance measurement. The instrument will display [---] as the capacitance if it
is unable to perform capacitance measurement.

*1. PV insulation resistance has approx. 660 k
Ω
of current-limiting resistance on the +
terminal, so the output voltage is divided by 660 k
Ω
and the resistance connected between
the measurement terminals.
Example: When open-circuit voltage is measured with a DMM with an input impedance of
10 M
Ω
, the voltage is divided by 660 k
Ω
and 10 M
Ω
.
