4) When the automatic testing is finished, the buzzer will hint by tweet (buzzer), VFD reads
the result of testing. If the testing passed, VFD reads PASS, or reads FAULT. Press▲、▼
also to observe the numerical value and result of every step.
5) Press Esc to back the automatic testing.
Select the Resolution between Low Range and High Range
1) Press Shift + Menu to enter into menu, VFD displays>CONFIG
2) Press Enter into the submenu, VFD displays>INITIAL CONFIG
3) Press▼to make VFD display RANGE SELECT
4) Press Enter to confirm, and press▼to choose ON
5) Press Enter to confirm
6) Press Esc to exit menu
Then you can press Shift +▲ to change the voltage range (maximum voltage). If the former
maximum voltage value is 120V and the resoulution is 10mV, it will become 18V when you
press Shift +▲ , and you will get 3 decimal points (xx.xxx) compared to 2 decimal points
before. Wheras if the former maximum voltage is 18V, you can press Shift +▼ to make it
become 120V, also the resolution will become as 10mV.
On the other hand, you can press Shift +▼ to change the currnet range (maximum
current). If the former maximum current value is 12A and the resolution is 1mA, it will
become 120A when you press Shift +▼, and you will get 2 decimal points (xx.xx) compared
to 3 decimal points before. wheras if the fromer maximum current is 120A, you can press
Shift +▼ to make it become 12A, and the resolution will become as 1mA.
