NOTE: The dielectric discharge test is suited for the insulation measurement of rotating machines, and in general, for the insulation measurement of heteroge-neous or multilayer insulation containing organic materials.
Using the R-DAR-PI-DD Function:Duringoraftermeasurement,theR-DAR-PI-DD buttonallowsyoutoscrollthroughthefollowingvalues:

NOTE: During the measurement, the DAR value is not available if the DD value was preselected before the measurement. The PI value is not available if DAR or DD values were preselected before the measurement.

NOTE: The input current may be a depolarization current resulting from an earlier insulation measurement. It is recommended to start a new DAR and PI measure-ment after the current has dropped to a negligible value (on the order of 100pA) to avoid variations on these measurements.
Dependingonthechoices(DARorPI),themeasurementgoesasfollows:

NOTE: This adjustment provides the best compromise between the measure-ment build-up time and the presence of external interference voltages (§ 4.2).
Ifnointerferencevoltageispresent,choose0.03toobtainarapidmeasurementbuild-uptime.
Example: If an insulation measurement is performed at a test voltage of 5000V and the limit is set to 0.10, it will be possible to perform a correct measurement with the pres-ence of an external interference voltage ≤500V, to the detriment of a longer measure-ment build-up time.

• Connecttheinstrumenttotheinsulatortobetested.• Start the measurement using the START/STOP button and read the
results.
WARNING: If an external voltage is present that is greater than the thresholds described in § 4.2, then measurement is prohibited.

NOTE: After replacing or completely discharging the battery, the message “Memory OFF” appears when you try to save a measurement in memory.
To be able to save your measurements, you will need to do the following:SettheinstrumenttoSET-UPandpresstheMEMbutton(thedisplayshows“MEMAllclr”).PresstheMEMbuttonfor2s(thedisplayshows“MEMALLFrEE”).Mea-surementsarenowreadytobesaved.

DATAVIEW® SOFTWARE
7.1 FeaturesDataView® has a simple, easy-to-use interface for configuring and running tests with the Model 5060, as well as, printing reports of the test results. There are many features that are available through DataView®.
Some of the key features are:
• Configures all functions of the Model 5060• Selects test voltage and runs tests from your computer with a simple click
and execute process• Captures and displays data in real time• Retrieves data from the instrument’s memory• Displays DAR, PI and DD ratios, Resistance, Capacitance and Leakage
Current Values• Plots graphs of manual and timed tests• Includes your analysis in the comments section of the report• Stores a library of setups for different applications• Provides consistency in testing, regardless of who performs the test
7.2 Installing DataView®
DO NOT CONNECT THE INSTRUMENT TO THE PC BEFORE INSTALLING THE SOFTWARE AND DRIVERS.
Minimum Computer Requirements:• Windows XP / Windows Vista & Windows 7 (32/64 bit)• 256MB of RAM for Windows XP 1GB of RAM for Windows Vista & Windows 7 (32 bit) 2GB or RAM for Windows Vista & Windows 7 (64 bit)
