Note:

1The max. range supports 0.01mF resolution & 1uF resolution & 0.1uF resolution, respectively. For

better stable display, 0.1mF @ 100/120Hz is recommended. The 0.1pF resolution for Cp mode

should be measured by test probe with good shielding.

S means equivalent series resistance for LC impedance measurement in series mode.

P means equivalent parallel resistance for LC impedance measurement in parallel mode.

For auto frequency mode, the best scale range is shown as the following table:

In auto frequency mode, the measurement mode in series/parallel is also recommended

to be automatic. Usually impedance ZDUT > 10kΩ is in parallel and impedance ZDUT <

10k

Ω is in series defaulted.
