 1920 Used in Eddy Current
Sensing
The 1920 LCR Meter is an all-purpose precise
instrument that has quite an interesting application in measuring the
conductivity of sensor plates. It's back to electromagnetics class for a short
discussion on eddy current properties and it's affect in transformers. Physics
is cool and science rules.

Ensuring the Safety of Medical
Electronics
James Richards, Marketing Engineer, takes a look at
electrical safety testing of medical products from the standpoint that safety
standards alone do not ensure the device is safe. That safety is as much a
function of product design as it is the manufacturer's test program.

Determining if a Device is
Connected Using a Low Trip Limit
Have you ever had trouble powering up an electronic
device and someone comes along smartly inquiring, "Well, did you plug it in?"
This happens to most of us, but when you're dealing with a DUT connected to a
hipot tester and the application of high voltage, prudence comes in the form of
a 'low trip limit'. [Full Text:

Power Factor of a
Capacitor
Is there a difference between the dissipation factor
and power factor of a capacitor? Yes and no. Investigate what physical and
electrical properties of a capacitor influence the dissipation factor equation.

EST 101 (IEC60601-1 and basic
electrical safety tests) - 5th article in a Series of 8
Check out this 5th installment of the IEC60601-1
Series for definitions of the electrical safety tests terms called out in
IEC60601-1. It also provides a short course in the four basic electrical safety
tests (ground, voltage, current and resistance) and illustrates their
respective setups.

Product
Spotlight: |
QuadTech's 1900 Series receives overwhelming
acceptance in a number of Industries. Here are some highlighted application
notes explaining the uses and applications in a few of the industries.
Low ESR Capacitor
Measurements
What is ESR and how does it affect capacitor
measurements? Investigate the technology and trends that have driven the
manufacture of capacitors with lower equivalent series resistance. Factors
affecting total loss and methods for making accurate measurements are discussed
also.

Analyze This Inductor
Inductor properties, like capacitor properties, can
be difficult to measure without performing analysis under real-time operating
conditions. The measured inductance is dependent on the current flowing through
the inductor. Knowing the precise current, being able to bias it or hold it
constant will help fully characterize the inductance of the device under test.

Testing Automotive Engine
Oxygen Sensors Using the 1900 Series Precision LCR Meter
The 1900 Series instrument has another interesting
application in the testing of the C value in the capacitive element of an
oxygen sensor used in automotive engines. Tests on the he ceramic capacitor
inside the oxygen sensor are done after sensor assembly due to the fragility of
the ceramic element. [Full Text:

Measurement of Dielectric
Constant and Loss
Need to measure the dielectric constant of a solid
or liquid? Integrate a QuadTech 1900 Series Precision LCR Meter and a
Dielectric Product's Type LD-3 Cell for a complete measurement solution. The
contact method, air gap method and two-fluid method are discussed and
illustrated plus calculations are given for determining the sample's
capacitance.
