RMO100A Getting Started
During the test, both green and red LEDs flash alternately. The display shows test curent
(here
100A
) and the current value of the measured resistance (
94,2
µΩ
). The time passed since
the test begining is also shown on the display (
00:35
).
Upon completed test (due to expire of selected time or due to push to the
STOP
button) at selected
memory location the last measured result will remain registered. By pushing
Ω
button current test result
is stored in internal memory.
Note:
In case of PC and RMOWin-R3A software use during the test, all performed measurements will
be registered. Results will be shown in a table in Excel format with option of additional edit and
graphic presentation.
Using RMOWin-R3A after testing for transfer of results from selected internal memory location to PC, it
is possible to transfer only the result of the last test.
To stop the test prematurely, press the
STOP
button at any time during the test. The current will
immediately drop to 0 A.

6.5 Viewing the Test Results
Once a Single test is finished, RMO100A automatically changes to the
Result
menu to display the test
results.
For Continuous Test only the last performed test is shown.
Note:
If the defined test current could not be reached, this could be due to a too high contact
resistance of the test object and/or of the current cables.
The test current value displayed here is the maximum test current reached.
