Note:
1. It may take some time (about 30 seconds for the 400μF
and 4000μF range) for steady readings when
measuring high capacity.
4.17 Measuring Capacitance
Beware of Electrocution.
To avoid electric shock, make sure that the
capacitors have been fully discharged before
measuring the capacitance of a capacitor.
WARNING
4.17.1 Plug the black test lead into the COM jack and
the red test lead into the INPUT jack.
4.17.2 Set the rotary selector to the range position.
4.17.3 After fully discharged the capacitor, connect the
test leads to the two ends of the capacitor for
measurement.
4.18.4 Take the reading on the LCD.
