User Manual MX Series CTSH Compliance Test System
8.3 Test Setup
The Test Setup Tab contains several controls that allow the user to configure the EN 61000-4-13 test to be
run on the EUT. The various settings are as follows:
Parameter Description
Phase mode The available phase mode is shown in the top right corner and cannot be
changed. For single-phase systems, phase A is always used as it is the only
phase. For three phase systems, all stimuli are applied to all three phases.
EUT EMC Class The test standard distinguishes between four classes of EUT, class 1 through 3
and a user defined class X. The user must select class 1, 2, 3 or X. Class X
levels can be set in the Test levels Tab but must be equal than or higher than
class 3 levels.
Nominal Settings These values are normally obtained from the AC source's steady state setting
when the test window is opened. They can be changed before running a test if
needed. Note however than frequencies other than 50 or 60 Hz are not covered
by the test standard.
Test Step Selection There are four main test categories that may be selected. Consult the test
standard for details on each step. Any combination of these four choices can be
made.
Test Options Prompt for EUT status: When checked, the program will prompt the operator for
a Pass or Fail determination after each test step selected in the Test Step
Selection box has been run. If this option is turned off, all test will be run and this
dialog will only appear when all test are completed.
IEC 725 Reference Impedance: If needed, the IEC 725 Flicker reference
impedance may be used during the EN 61000-4-13 test.
Voltage THD: When checked, the test program performs an AC Source voltage
distortion pre-test and displays the result in the Voltage THD Tab.
Source Regulation: When checked, the test program will checked the AC
Source output voltage regulation with the EUT connected to ensure the AC
source meets the test standard requirements.
User Data The fields at the bottom of the Tab may be used to enter information on the
person or entity performing the test, the EUT and any other comments that may
be relevant. This information will be incorporated in the test report.
User selected EUT Class, test steps, options and nominal values are all included on the EN 61000-4-13
test reports.
8.4 Test Sequence
The EN 61000-4-13 standard specifies the test flow diagrams shown in the next two pages per EUT test
class 1, 2 or 3. The operator is responsible for following the correct flow diagram.
