61000-3-12
Setting with measured monitor values displayed (61000-3-12
2004 only)
The monitor values of real-time measurement are displayed in the upper part of the setting
item display. The measured monitor values indicate the current status of the EUT. This
function does not observe all operation cycles of the EUT.
6 Rated Current lequ (A) Enter the rated current value of the EUT. For an unbalanced three-phase
device, enter the value of the maximum current that flows in one of the
three phases. This item is used for calculating the Sequ value.
The input range is 0.0 A to 75.0 A.
Enter the value with the numeric keypad and press the ENTER key, or
use the large knob to increase or decrease the value. 20.0 A
7 Nominal Sys Volt Unom
（
V
）
Enter a nominal system voltage. This item is used for calculating the
Ssc value.
The input range is 100 V to 600 V.
Enter the value with the numeric keypad and press the ENTER key, or
use the large knob to increase or decrease the value. 230 V
8 Nominal Frequency Select the rated power frequency of the EUT. 50 Hz
9 Return Terminates the specification of the rated voltage and frequency. –
10 To Meas Setting Page Switches to page 4/4. –
11 Prev/Next Page 1/4 Switches to another menu page. –
F key: Function key. You can also use the ESC key to return.
If you want to use the values (specific values) specified by the manufacturer in place of the
actually measured values for the rated current lequ, fundamental current (Iref), and standard
fundamental current (I1) of the EUT, select "Measured" to execute the test. Then, check that
the specified value is within ±10 % of the measured value, and execute the test using
specific values.
Write the test results using measured values in the Memo column of the report for tests
using specific values, or prepare each report separately and use them together.
Testing is possible even when the difference between measured values and specific values
exceeds ±10 %, but it is important to note that the limit value of the obtained test results does
not meet the standard.
