The 253 Digital Impedance Meter auto ranges and measures capacitance, inductance, resistance, dissipation factor, and conductance at a fixed test frequency of 1 kHz. The 253 uses a 4-wire Kelvin clip test cable that ensures repeatable measurements. The 253 features a 3.5 digit LED display with LED annunicators to indicate range and units. The 253 basic accuracy is 0.25%.
