Checking the AC Power Supply and Repeatability
Checking the AC Power Supply
Use this menu to check the performance of the AC power supply (voltage, voltage distortion
factor and frequency). Check the performance using the LOAD terminal of this product. When
the test conditions are set before the test is executed, judgment (PASS/FAIL) is made by real-
time measurement. After the test is executed, judgment (PASS/FAIL) is made from in-test
measurement values.
When the connection cable to the EUT is long, standard requirements may not be satisfied
because of an increase in voltage drop and inductance.
●
Operation when the following standards are selected and operation of this product
• IEC 61000-3-2 standard
Jjudgment (PASS/FAIL) is made from the measurement values after the test.
• JIS 61000-3-2 2005 standard (Using reference impedance), JIS 61000-3-2 2019
standard (Using reference impedance) or IEC 61000-3-12 standard
Before starting the test, remove the equipment under test (EUT) and check the
AC power source.
Press the F2 (Record) key to record the measured values. If you do not record
the values, when you set Select View Items to Measured Values, the correct
values will not be displayed.
After the test starts, the recorded values will be displayed.
