Measuring capacitance
IMPORTANT: If capacitors are
poled, the display unit handle
must be applied to the capaci-
tor's positive pole.
NOTE: No bar graph display is
given for capacitance measure-
ment.
Capacitance will not be meas-
ured, if the capacitor being
measured is charged. The
capacitor may, for example, be
discharged by pressing the
"LOAD" button.
