PRECAUTIONS FOR USE
The protection obtained by the instrument can be compromised if it is used in a
way that is not recommended by the manufacturer.
■ Do not attempt to perform any tests with this instrument until you have read
the user manual.
■ Tests are to be carried out on de-energized circuits only! Never connect the
unit to a live circuit.
■ The micro-ohmmeter must be connected to the earth/ground point, through
the ground terminal or the power cord.
■ Be sure the power cord is accessible at all times, in case the instrument
needs to be quickly unplugged for any reason. Always disconnect the power
cord before performing any repair on the instrument.
■ Do not obstruct either the intake vents or the fan, to avoid overheating.
■ During a circuit breaker measurement its contacts must be closed and
connected to an earth/ground point. The end connected to an earth/ground
point must be connected to the “C-” terminal.
■ Ensure the terminals are free of any voltage in relation to earth/ground point
and between each other. Take into account that in a substation you will nd, in
disconnected points, high potential levels in relation to the earth/ground point.
Those potentials are caused by presence of electromagnetic elds and can
be minimized following the indications in the paragraph before.
■ Make sure that the current connections are well connected to avoid
undesirable heating.
■ Be careful when manipulating the current terminals in the instrument.
High temperatures may occur in the current connections.
■ Never connect or disconnect the cables during a measurement. If a
modication must be made, press the STOP button rst.
■ The micro-ohmmeter should never be used in an explosive environment (this

2. PRODUCT FEATURES
2.1 Description
The AEMC® Model 6292 is a portable high-current micro-ohmmeter that incorpo-
rates optimized lters and protection for measurements in electrical substations.
The Model 6292 can be used to accurately measure very low contact resistances
on high voltage circuit-breakers and switches, busbars, etc., with test currents up
to 200A. It employs the four-terminal method Kelvin principle to eliminate errors
caused by test leads and their contact resistances.
The AEMC 6292 incorporates a technology known as True DC. Its high frequency
switching system outputs very low ripple less than 2% of full range. Measurement
accuracy is guaranteed through a state-of-the-art signal amplication system,
oset-free with high long-term stability. Resistance readings are shown in the
alphanumeric display with up to 4½ digit resolution. It allows measurement
of resistances up to 1Ω with resolution as low as 0.1µΩ. Test currents can be
adjusted by the operator and are displayed on the digital display.
The Model 6292 has an internal memory for storing up to 8000 readings. These
stored readings can be downloaded to a computer through a USB interface. The
advanced high current generation system signicantly decreases both weight
(24 lbs [11 kg]), and size. The hard plastic case is highly resistant to impact and
environmental conditions. Internal thermal sensors in all sensitive components
prevent overheating damage to the instrument.
This rugged but light-weight instrument can easily be carried by one person.

■ The rst line shows the resistance under test (100µΩ).
■ The second line shows the current through the resistance.
■ The third line indicates the elapsed time and (in timed tests) the duration of the
test. The example above is a timed test. The elapsed time is 15 seconds and the
total time is 60 seconds, so in this case the test still has 45 seconds to run. In an
Unlimited time test, the third line simply shows the elapsed time.
■ The fourth line shows the present date and hour.
■ To end a test for which the duration has been set to Unlimited, press the STOP
button.
20 Micro-ohmmeter Model 6292
4.9.2 Both Sides Grounded (BSG) Mode

In BSG mode, the instrument will display the screen below:
R=100.0uΩ
It=142A Ig=8.0A
DURATION: 015/060s
10/20/13 03:25 PM
The data displayed on the screen is basically the same as in NORMAL mode.
The dierence is the indication of “Ig” current measured by the current probe.
The second line shows:
■ It - the current running through the resistance.
■ Ig - the current running through the ground.
4.9.3 Making Current Adjustments
During a test with preselected current, you can make current adjustments
“on the y.” Pressing the rotary knob during a test enables MANUAL mode.

TEST COMPLETED
Memory Full
If the memory is full, you must erase some objects or tests to free up memory
space for saving new tests, as explained in the next section of this user manual.
When saving a test, the following information is stored in the internal memory:
■ Name of the object
■ Test number
■ Current of test (in BSG mode, both the test current and ground current
are displayed)
■ Partial, nal and total time of test
■ Measured resistance
■ Date and time
NOTE: An object can contain several tests, and a test can contain several
results.
4.11 Storing Objects in Memory
The storage capacity for the Model 6292 is approximately 1600 readings to 8000
readings depending on how the tests are stored. For example, if a new object
is created for each measurement, only around 1600 results can be saved. But if
the name of the object is never changed, it is then possible to save up to 8000
measurements.

5.2 Micro-Ohmmeter Control Panel
Clicking the DataView icon in the DataView folder on your desktop opens the
core DataView program. Clicking the MicroOhmmeter Control Panel icon opens
the MicroOhmmeter Control Panel.
In general, core DataView features are for creating, viewing, editing, and storing
DataView reports; while the Control Panel is for connecting to, conguring,
viewing measurements on, and downloading data from the instrument. You
can access all DataView features through either the DataView icon or the
Control Panel icon. For users who interact with micro-ohmmeter instruments,
we recommend primarily using the Control Panel. However, there are situations
where using the core DataView icon may be more convenient for some users,
such as when viewing multiple archived reports from dierent AEMC product
families.
For further information about using the MicroOhmmeter Control Panel, consult
the Help system that comes with the product. Access this Help by clicking the
option Help in the Control Panel’s menu bar at the top of the screen.
