The test can be repeated as often as desired for various protective conductor parts with the manual sequence*. Switch line voltage to test socket, start measurement Reverse mains polarity, perform measurement again Framed with dashed line: The test is only run if it has been activated in the initial program window, or in the Setup menu under Sequence ... * If it is not clear whether or not all exposed, conductive parts are connected to one another or to the protective conductor, testing can be performed in the manual mode. Yes No No Start function test IL OK? Yes Switch line voltage to test socket, start function test Display results (for combination testing: additional display of differential resistance), save/print report GOSSEN METRAWATT GMBH 11.6 Testing Devices in Accordance with DIN VDE 0702:2004 Check connection parameters and start test. The following measurements can be performed in accordance with the above mentioned standard: • Protective conductor RPE (permanent connection or with plug) Test current: DC ±200 mA • Insulation measurement RISO (can be deactivated, e.g. if danger exists that voltage sensitive components in data processing systems might be damaged) plus equivalent leakage current or • Contact current for safety class II or • Differential current To Socket Class Ext. Cable ISO-R ID No. Setup … This is the default setting. Refer to chapter 7 on page 14 for other types of connection. If the test instrument is equipped with features B00, 01 or 03, and if the DUT has been connected to the test socket, safety class recognition is performed (SC I or SC II). Otherwise, the safety class must be specified manually. x: Extension cables or connector cables which are longer than 5 m can be tested with the help of the EL1 adapter (optional), either separately or in combination with a device. x: Insulation resistance measurement is performed. See parameters database in chapter 11.2 on page 27. See chapter 11.2 on page 27 regarding setup of the measuring sequence.

This value may not exceed 1 . for permanently connected data processing systems (DIN VDE 0701, part 240). Extension and Connector Cables Longer than 5 m Per DIN VDE 0702, an additional cable resistance of 0.1 ., however, not more than 1 ., is allowable as of a length of 5 m for each additional 7.5 m. Resistance testing for cables longer than 5 m is thus advisable (see also limit values on page 17). . Note The EL1 accessory adapter is required for testing for shortcircuiting and interruption of single-phase extension cables. Connecting the Extension Cable or the Multiple Outlet Note.The keys in the adapter’s handle have no function. PROBE 5 4 (21) EL1 SECUTEST Device Under Test = Extension Cable . Connect the extension cable to the EL1 adapter as shown in the figure above. . Select the “Ext. Cable” test from the initial menu with the cursor and acknowledge with the key: Ext. Cable x WITH EL1. . Select “Start Test” with the key. . Start the measurement sequence with the key. . First perform and acknowledge visual inspection of the extension cable. . Enter the length of the cable with the and keys. Acknowledge with the key. GOSSEN METRAWATT GMBH 11.8 Testing Multiple Outlets for VDE 0702 (optional EL1 adapter) . up to version 5.10: Do not select “WITH EL1” in the initial menu. The following must appear in the line: Ext. Cable – WITH EL1. “Manual sequence” must be selected. . from version 5.11 onwards: Select “X WITH EL1” in the initial menu. The following must appear in the line: Ext. Cable X WITH EL1. “Manual sequence” must be selected. . A visual inspection must always be performed. It may thus be necessary to unreel the cable from its drum or reel. . Protective conductor resistance measurement: Contact the first outlet with the EL1 adapter. Each time you are ready to contact the next outlet, press the key to repeat the test. .
