LQ-9101
User Manual
Although the absolute accuracy of the instrument is not so high, it may be helpful to select the matching
resistor element for actual operation. Similarly, 1.000K and 1000Ω 1.000MΩ and 1000KΩ mean the same
inductance and similar values: 1000nH and 1uH 1000uH and 1mH 1000mH and 1H... Capacitance also
has similar values: 1000P and 1.000nF 1000nF and 1uF 1000uF and 1mF... The characteristics of the
above values all occur at the juncture where the unit spans.
7.21 What is the difference between the LQ-9101 and the cheaper inductors and capacitors on the market?
One or two hundred dollars or even a few dozens of inductors and capacitors have products, most of
which are self-resonant resonant schemes. Measured and inexpensive, general use is cost-effective.
The differences are mainly as follows: the operating frequency of the self-resonant resonance scheme
is indeterminate, and varies with the parameters of the measured component. Capacitance and inductance
parameters can be measured. The quality factor and loss factor of these two components cannot be
determined. The accuracy and stability depend on the internal reference capacitance and reference
inductance; LQ-9101 has a definite measurement frequency that can be selected to accurately refect the
parameters at the determined frequency of the device under test. The vector measurement principle used
can measure the quality factor and loss factor of an element or the equivalent parameters of different
models. Accuracy and stability depend on internal reference resistors. Highly stable reference resistors are
easy to obtain and use. The former uses capacitive and inductive reference components far less than the
latter's high stability resistors. Therefore, the LQ-9101 must have high stability. Many, functional and
measurement levels are equivalent to current mainstream bridge products.
