ESI 250DE

Portable Impedance Bridge

The 250DE Portable Impedance Bridge is a completely self-contained, portable instrument for precision measurements of resistance, capacitance, and inductance. It can also be used to measure dissipation factor and storage factor for capacitors and inductors. Its accuracy is conservatively rated at 0.1% for resistance, 0.2% for capacitance, and 0.3% for inductance. Even greater precision is possible for comparative measurements because of the 12,005 divisions of dial resolution. Frequency of 1kHz Resistance range is from 0 to 12 Mohms in eight ranges Inductance range is from 0 to 1200 H in seven ranges Capacitance range is from 0 to 1200 ?F in seven ranges
