Fig. 8.5.2-2: CapacitorChecking
Switch the multimeter to „Continuity: acoustic signal“ and
touch both capacitor terminals with the meter end probes.
Test each capacitor by touching the multimeter (set on „continuity“) end probes on the capacitor terminals: only a
brief „beep“ should be audible from the multimeter.
Once this has been done, reverse the end probe positions and repeat the check. (The multimeter battery charges
the capacitor and then the capacitor discharges quickly. The discharge to the multimeter „closes“ the circuit briefly
and continuity is achieved for a brief instant causing the short „beep“.)
If there is no beep at all or there is a continuous beep, then the capacitor(s) is faulty and needs to be replaced.
Inductance is measured in the same way as the ohmic resistance, i.e. the coils are compared. The value is indicated
in mH (milli Henry).
The arranging value for the inductive resistance can take from the Table 9.4, “Technical data coil,” on Page 129.
Note: These values depends strongly from the measuring method (kind of the measuring instrument)
