RMO60TD Getting Started
Note:
Using DV-Win the results could be stored to a PC, where reading interval results is adjustable. Results
will be shown in a table in Excel format with an option to perform additional edit and graphic
presentation.
Using DV-Win after the test in order to transfer the results from selected internal memory location to a
PC will allow transfer of the last test result only.

The highest resolution of the reading is always displayed; resistance range selection is performed
automatically and therefore is not necessary to be set by the operator.
Accuracy
Typical accuracy of RMO60TD is
± (0,2 % rdg + 0,2 % FS). This accuracy is valid if the maximum
possible current is used. Always try to use as high current as possible, but to avoid the risk of heating the
winding, it is recommended not to exceed from 10 % to 15 % of the nominal current of transformer. It is
important to get a good connection between clamps and the connecting point on the test object to
achieve stable and accurate test results. Guaranteed accuracy is
± (0,4 % rdg + 0,4 % FS).
Viewing the Test Results
Once a test is finished, RMO60TD automatically changes to the
Results
menu to display the test results.
