15 Measurements in Accordance with National and

International Standards with Selector Switch in Auto Position

If measurements need to be performed in accordance with given stan-

dards which require specific tests, and if results need to be stored and

documented with a test report, an automatic test sequence is advisable

instead of individual measurements.

Note

for tests per EN 60950, EN 61010 and EN 60335

The DUT must be connected to the test socket for the automatic

test sequence! The DUT must comply with safety class I or II.

õ Connect the test instrument to mains power.

A mains connection test is initialized (see chapter 3.2 on page 12).

Connect the DUT to the test socket at the test instrument (see

chapter 7 on page 17). The test instrument initializes

connection type recognition

õ Set the selector switch to the Auto position. If the DUT has been con-

nected to the test socket, safety class recognition is performed. Other-

wise, the safety class must be specified manually. In the initial program

window, move the cursor up with the

key into the third line and ac-

knowledge with the key. A safety class can now be selected with

the

and keys and acknowledged with the key.

õ In order to select the regulation for which testing is to be performed,

move the cursor up within the initial program window with the

key

into the top line and acknowledge with the key. The desired stan-

dard can now be selected with the

and keys and acknowledged

with the key. If you always want to test in accordance with a spe-

cific standard, this can be stored as the default standard in the setup

menu. Otherwise, the selected standard only remains active until the

test instrument is disconnected from mains power (factory default set-

ting: VDE 0701-0702).

õ The test sequence can be configured in the Setup… menu, limit values

can be changed if necessary and database options can be configured.

õ The test sequence is started by selecting Start test and by acknowledg-

ing with the key (see “Test Sequences”).

Tests which have already been included in chapters 9 through 14 are not

described here again. The only exception is measurement of extension

cables.

15.1 Test Sequences

Test sequences for the various standards are always run in the same

order, assuming that the device under test has been properly connected

and the mains connection test has been passed.

The test sequence can be run step by step with manual activation of each

subsequent step if this function has been specified, or automatically. Step

by step manual operation can be selected in the initial program window in

the setup menu under “Sequence” ... “manual sequence”.

• Safety class: SC I or SC II is automatically recognized by the test instru-

ment. If the safety class is not correctly recognized, you can change it

manually. This manual correction is not stored however.

• Visual inspection: If “visual inspection” has been activated

in the initial program window under “Sequence”.

If a part is recognized as defective by the user, it must be identified as

such by selecting it with the cursor and acknowledging with the key.

•

Protective conductor resistance measurement

(for SC I devices under test only)

Note

This test cannot be skipped. Exception:

This measurement can be skipped by pressing

(when mes-

sage „Connect probe to protective conductor“ is displayed) if a

protective conductor connection is not possible.

• Evaluation of protective conductor testing

• High-voltage test for DIN VDE 0701 Part 1, Appendix E, EN 60950,

EN 61010, EN 60335, EN 60601, if selected in the setup menu.

• Insulation resistance measurement

IEC 62353: only if selected in the setup menu of the

initial program window under “Sequence ...”

EN 60601: only if selected in the initial program window

under „Test Conditions“

DIN VDE 0701-0702 only if R-INS is activated in the initial program

window

• Evaluation of insulation test

• Leakage current measurement (various single-fault conditions are run de-

pending on classification)

• Evaluation of each individual leakage current measurement, see also

chapter 21.2

• Evaluation of the overall test
