Welcome to the AEMC Model 6292 MicroOhmmeter.
This is part 1 of a 2-part video on the AEMC Model 6292.
In this first video we will show you how to set up and run a basic test from the front panel controls.
We will then store the result in memory. Part 2 of this video will show you how to
connect the instrument to the DataView control panel,
download the test stored in memory and create a DataView report.
Here's the 6292 and we will be using a 166 micro-ohm shunt for the test,
shown here,
For our demonstration
we have connected a 166 micron shunt to the instrument shown here.
For this test we will run a 20 second test in normal mode
with a current of 50 amps. During this test we will take partial measurements
at five second intervals and store the results in the instrument's internal memory.
The instrument's
front panel interface shown in frame here includes an alphanumeric keypad
for typing in information, function keys
for displaying and working with system options and buttons
for starting and stopping tests and for selecting the test mode. There's also a
rotary knob for navigating through and selecting menu options
and for adjusting test current during manual mode testing. All information is
displayed on the instruments large
LCD display screen. We will now set up and run a test on the 6292.
To set up a test push the menu function key, this displays the main menu.
Select the setup test option by pressing down briefly on the rotary knob
the setup test menu appears. Select the option
"edit object name" by pressing on the rotary knob.
Tests performed on the model 6292
are stored in data records called objects.
Each object can contain multiple tests
For our demonstration we will name our object
"EXAMPLE1" using the alphanumeric keypad.
After entering the object name, press the rotary knob
to save it and return to the test setup menu.
Then turn the rotary knob counterclockwise to move the selection arrow on the LCD screen
down to the option "test current".
Press the rotary knob to display the test current menu, again,
turn the knob to select the current setting for the test.
The menu offers 4 fixed current settings
50 100 150 and 200 amps
You can also select the manual option. This option allows you to control the
amperage during a test by turning the rotary knob.
In the manual mode the current is limited to 100 amps
in our test we will choose 50 amps.
We now choose test duration to select the length of the test.
There are two options: Timed and Unlimited
As the name implies, Unlimited is for an untimed test
the test will run continuously until you press the start button.
We want to set the test duration so we select Timed.
There are two ways you can enter the duration: one is by using the keypad
to type in the number of seconds you can also turn the rotary knob to select a
higher or lower number.
For timed test the minimum duration is 5 seconds and the maximum is 120 seconds.
In our demonstration we will select 20 seconds.
After setting the duration
you must press the rotary knob to save the setting to return to the setup test
menu. We will then press the menu button to return to the main screen
The final step
in setting up the test is to select the test mode. There are two options:
Normal and Both Sides Grounded represented on the display as BSG
You select the mode by pressing the blue
mode button. In our test we will select
normal mode.
The display will now indicate that we are ready to run a test. The name of the object that
will contain a test appears at the top of the screen.
The second line shows we running the test in "normal mode"
at 50 amps for 20 seconds
To begin the test, press the green Start button. After a few moments
the LCD display indicates the test is underway
a feature of the Model 6292 is the ability to save partial test results.
To do this we will press the Save button
every 5 seconds during test. This allows us to save partial measurements
at 5, 10, and 15 seconds as well as the completed measurement at 20 seconds.
All these measurements will be stored in a test record within the object we've
named "EXAMPLE1". When the test is finished the message "TEST COMPLETED"
appears blinking on the screen. Press "SAVE" to store the test in the Model 6292.
We will then press the escape button to return to the main screen
Now that we have tests stored in memory, you can now view the saved test by
pressing menu and selecting the memory option with the rotary knob.
This displays the "memory recall"
menu. Select the recall option with the rotary knob.
This displays information about the test including
the name of the object containing the test,
the number of tests in the object, and the date of the stored test.
To view the stored test, press the rotary knob
this screen indicates that our test is stored as the first record
in the "EXAMPLE1" object. It also shows that there are 4 measurements
in the test. 3 partial measurements we took at 5 second intervals
and the final result. Press the rotary key to view these measurements.
The stored test result shows on the top line
the resistance measurement at the 5 second point in the test,
which in this case is 167.2 micro-ohms.
The second line shows the test current which we set earlier
at 50 amps. The third line shows the test duration.
Here we show the test result was obtained at the 5 second mark
within a 20 second test.
The bottom line will show that this is the 1st of 4 measurements stored
within this test. To see the remaining measurements
turn the rotary knob to step through the test results.
The final result is shown as 165.4 micro-ohms at the 20 second mark.
this concludes part one of our demonstration. In part two of this video
we will show you how to connect the instrument to Dataview control panel,
download the tests stored in memory and create a Dataview report.
