Powered by a 9-V battery, the Model Z580 from Protek measures inductance, capacitance, resistance, and impedance at a rate of 3 measurements/s with basic measurement accuracy of ±0.3 percent. The handheld meter displays component value, along with its Q or D, directly on its 5-digit dual display, or in a Δ or Δ% format.
A built-in comparator allows four-bin sorting with a pass or fail warning. The Model Z580 also provides open and short circuit calibration for accurate zeroing, series and parallel equivalent circuit modes, auto-ranging and range-hold functions, and automatic power off. Test frequencies include 100 Hz, 120 Hz, 1 kHz, and 10 kHz; test voltages include 0.1 V, 0.3 V, and 0.42 V.
The Model Z580 provides measurement ranges of 0.0001 ohm to 999.9 Mohm (resistance); 1 µH to 9999 H at 100 Hz and 120 Hz (inductance); 0.1 µH to 999.9 at 1 kHz and 10 kHz (inductance); 1 pF to 9999 µF at 100 Hz and 120 Hz (capacitance); 0.1 pF to 999.9 pF at 1 kHz and 10 kHz (capacitance); and 0.0001 to 9999 (D or Q).
The Model Z580, which is just 3.54x7.9x1.56 in., comes with an AC/DC adapter, test lead adapter with Kelvin clips, and a rechargeable 9-V battery pack.
