1~7. Same as the operation steps in the previous section;
8. Set VT ratio (display B);
9. Confirm;
10. Set CT ratio (display C);
11. Confirm;
12. Set SF ratio (display D);
13. Confirm;
14. Exit and close the setting menu.
It is operated according to the above steps 1 to 7. After entering the scaling setting interface, Display Bar A is used to
display the currently set input unit, Display Bar B is used to set VT ratio, Display Bar C is used to set CT ratio, and Display
Bar D is used to set power factor.
Description of scaling function
VT ratio
When the secondary output of VT is connected to the voltage input terminal, the VT ratio is set. The voltage range is then
set based on the maximum value of the VT output. The setting range is 0.001 ~ 9999.
CT ratio
When the secondary output of the CT or the output of the current sensor is connected to the current input terminal, the
CT ratio (or the conversion ratio of the current output type current sensor) is set. Then, the current range is set according
to the maximum value of CT or current sensor output. The setting range is 0.001 ~ 9999.
Power factor
By setting the power factor (SF), the active, apparent, and reactive power measurements multiplied by the factor can be
displayed. The setting range is 0.001 ~ 9999.
Setting method
The set factor value can be added and subtracted by operating the navigation (up and down) key. The number of digits is
set to move to the right by one digit by operating the navigation right key, and the value of adjacent digits on the right is
set. The decimal point position of the value is moved by operating the navigation left key. The decimal point moves to the
right by one digit in each press. After the numerical value setting is completed, the "Enter" key is pressed for confirmation,
and the skip flash cursor will move to the next display bar until the VT ratio, VT ratio and SF ratio are all set.
⚠ CAUTION
If VT, CT and SF of Channel 1 are all set to 10, the current, voltage and power of Channel 1 are amplified by 10 times, 10
times and 1,000 times respectively (VT*CT*SF).
The scale is set, and the current and voltage range will not change.
