5.4.2 Checking AC Power Supply and Repeatability
Menu
Use this menu to check the performance of the AC power supply for a test. Check
the voltage, voltage distortion factor, and frequency using the LOAD terminal of
this product. When the connection cable to the EUT is long, standard requirements
may not be satisfied because of an increase in voltage drop and inductance.
Judgment results are displayed as “PASS” or “FAIL.” Depending on the
requirements of the standard, the judgment timing is as shown below.
Table 5-9 AC Power supply check timing
•
To prevent an electric shock, do not touch the SOURCE or LOAD
terminals of this product.
•
Do not touch the OUTPUT terminal of the AC Power Supply.
•
Do not touch the INPUT or OUTPUT terminals of the Line Impedance
Network.

Realtime measurement and judgment is performed
when tests are not being executed.
When you select these standards, you have to perform
judgments with the EUT turned off before you start the
test.
