(1) Turn unit on.

(2) Set the mode switch to the “LCR” position.

(3) Set the Function/Range switch to the appropriate resistance

range. If the value of resistance is unknown, select the 2 ohm

range.

(4) Using a short piece of wire, such as a paper clip, temporarily

connect the po sitive and nega tive m easurement terminals

together. A lternatively, if t he clip leads w ill b e u sed for the

measurement, plug them into the banana jacks and connect

the clips together.

(5) Use a small, flat-blade screwdriver and slowly turn the “O Adj”

control to calibrate the display for a zero reading. Remove the

calibration short.

(7) Insert the resistor leads into the component test sockets at the

front of the meter. If the leads are too short, use the alligator

clip leads provided with the instrument to connect to resistor.

Measurement Parameter Conversions
The paramet er va lue for a co mponent mea sured in a parallel

equivalent circuit and that value me asured in a series equivalent

circuit may be diff erent fro m ea ch o ther. Th is means t hat the

parallel-measured capacitance (inductance) of any given capacitor

(inductor) will not be equal to the series-measured capacitance

(inductance) unless the dissipation factor of the capacitor (inductor)

equals zero. The equat ions in t he tab le be low sh ow the
