1) Do not use the meter in an extreme environment, especially dusty environments,
near high radiation, or around flammable substances.
Please abide by the following instructions to ensure safe use of the meter:

The 72-10465 LCR meter features an easy to read dual display measurement of
19999/1999. It also has serial and parallel measurement modes which can be used to
select quality factor, loss factor, phase location angle, and equivalent resistance of
measure articles. Intelligent detection and five different test frequencies enable
accurate readings for all sizes of capacitors and inductors. The user can also access
the stored data on a PC with the included USB connection and interface software.
The compact size and case make this unit far more portable than a benchtop meter.

2) Do not attempt to alter, repair, or calibrate the unit yourself. Such work should only
be done by a trained professional or as directed by your distributor.
3) Do not attempt to modify the meter, break insulation, or remove working parts.
4) Be certain that all circuits have been shut down and are free of voltage.
5) Do not apply any input voltage to the meter. Be sure to discharge any electrified
components such as capacitors.
6)This meter can be powered by two different methods. The first is by a 9V battery,
and the second is by the included USB cable. USB will also allow the unit to sync
data while it is being powered to save the life of the battery.

Impedance measurement instruments can be classified as DC impedance and AC
impedance types. A general multimeter can be used to measure DC impedance,
while a bridging instrument (such as this) can be used to measure AC or DC impedance.
The 72-10465 is an intelligent double-display portable LCR digital electric bridge,
with DC & AC impedance measurement functions. Impedance is one of the most
fundamental parameters to analyze electronic elements and circuits. The resistance
of linear diode is defined by Ohm's Law as part of a DC power scenario. Ratio of
voltage and current is a complex impedance as part of an AC power scenario. One
impedance vector includes one real part (resistance R) and one imaginary part
(reactance X). Impedance is expressed by R+jX in a rectangular coordinate, or
expressed by the amplitude of real Z and phase angle of 0 in a polar coordinate
system. See figure 1-1 for relationship.
