Measuring an Individual Speaker
4. Individual speakers are typically between 2W and 16W. For these
types, the 20W setting should be used. Some special application speakers
may be of much higher impedance. Speakers of up to 2KW (2000W) may
be measured using the 200W or 2000W setting. These higher settings also
allow measurement of speakers when connected to impedance matching
transformers or volume controls. In these cases, the speaker should be
connected to the meter as shown.
