Before measuring, be sure to turn off the power to the
measurement circuit. Otherwise, electric shock may
occur or the instrument may be damaged.

• When measuring the polar capacitor
Connect the V terminal (red test lead) to the + terminal of
the capacitor and the COM terminal (black test lead) to the -
terminal.
• For components on a circuit board, measurement may not be
possible due to the effect of the peripheral circuit.
• If the capacity changes when the measurement range is
changed (p. Appx.3)
