DESCRIPTION
1.1 INTRODUCTION
Model 252 Digital Impedance Meter is a semi-automatic instrument which permits rapid
measurement of inductance (L), capacitance (C), resistance (R), conductance (G) and dissipation
factor (D) at a test frequency of 1kHz. Measurement accuracy and versatility satisfies most
demanding engineering or Scientific applications.
To operate, merely push the button for the desired function, manually turn the knob to the desired
range, and connect the unknown. KELVIN KLIPS® test leads are included, thus ensuring true four-
terminal connections. The position of the range switch, used in conjunction with the desired
function button and front panel range scale, indicate the unit of measurement being displayed by the
3-1/2 digit LED readout.
Excellent reliability of the Model 252 is assured through use of solid-state devices and etched circuit
board construction. Its small size is ideal for use on bench tops where work space may be at a
premium. The carrying handle tilts the unit to a convenient viewing angle. Rear panel brackets
provide line cord storage and enable it to be operated in a vertical position.
