Measures capacitance (0.7% basic accuracy), resistance (0.5% basic accuracy) or inductance (0.7% basic accuracy). While displaying the reading on a 4 digit, 10,000-count LCD, it also displays the dissipation factor of capacitors or Q of inductors on a 3 digit, 1000-count LCD display. Unit features two selectable test frequencies (120HZ and 1kHz), auto/manual ranging, low battery indicator, auto power-off, and a relative mode that displays the difference between the measured and reference values. A unique tolerance mode beeps to indicate if components are outside a 1%, 5% or 10% tolerance around a reference value. The meter also "remembers" minimum and maximum values, and keeps a running average of tested component values. Operates on either 9V battery (not included) or AC adapter (included), measures 7.6"H x 3.5"W x 1.5"D, and weighs 13.8 oz. Comes complete with manual, test leads, AC adapter.
