Measuring Electrostatic Capacities (DT4252, DT4253, DT4255, DT4256)
3.8 Measuring Electrostatic Capacities
(DT4252, DT4253, DT4255, DT4256)
The capacity of the capacitor is measured.
WARNING
Before measuring, be sure to turn off the power to the
measurement circuit. Otherwise, electric shock may
occur or the instrument may be damaged.
Do not measure the capacitor which has been charged.

• 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.
