Whether you are new to testing or
repairing electronics, you will need a wide range of equipment, that
spans from a simple screwdriver to high sophisticated meters that
will provide a great help to solve your electronic problems. Whether
a newbie or if you have any experience, and want to update yourself
with the best products online, this informative text will make your
decision easy as connecting wires. Below I'll go over certain points
you need to know and will narrow down the choice to two most reliable
micro ohmmeters on the market.
First of all, an ohmmeter is an
electronic device that calculates electric resistance (reminder to
those who slacked in physics Ohm is a measuring unit (Ω)) which is
the natural opposition the electrical power. There are two types of
resistance meters Micro-ohmmeters and Megohmmeters. The Megohmmeters
also know as Megger, are designed to measure high values of
electrical resistance. On the other hand, micro ohmmeters, also known
as micrometres, measure the lowest resistances.
After an extended research on the
Australian market, I have come to the top two micro-ohmmeters for
your choosing.
AEMC 6240 Low Resistance Micro-Ohmmeter Ductor Tester
Buying the AEMC 6240 ohmmeter, it just
like buying a new premium car that spends low gas! The design is
practical yet appealing. On the outside rugged, this ohm meter is the
perfect partner for your extended testing periods. The most appealing
thing from this meter to newbies and professionals is the margin of
how much low resistance can take (0.25%) when you are doing a doctor
test. Using the Kelvin method, the AEMC 6240 measures everything from
1µΩ to 400Ω with different currents (1A, 10A, 100mA and 10mA with
polarity function also integrated).
The AEMC 6240 is best suited to do a
test on both inductive and resistive materials. In the same time, it
offers a capacity to save 99 measurements that can be printed
directly using a connection to a computer. One thing in particular
that caught my eye was the software included in the package, allowing
you easy ways to configure the instrument and compare the test
results.
AEMC 6292 Programmable 200A Low Resistance Micro-Ohmmeter Ductor Tester
From the same manufacturer comes
another great product - The AEMC 6292. Portable, equipped with a
high-quality microprocessor inside, it is optimised with different
filters and protections to measure different electrical substations.
Like I mentioned before, the AEMC
ohm-meters offer great accuracy and the same applies for the 6292.
Working on the same Kelvin principle, the 6292 is best suited to
calculate low resistance on very high voltage switches, circuits
breaker and much more electrical current up to 200A. Always
integrated with the newest tech, AEMC made the 6292 to have the best
signal amplification system with great resistance readings and
alphanumeric display with decent digit resolution.
