If you need only the CT, please check this: >>>HereMany buyers are response:
Why test data is wrong? Voltage * Current = Power, But power is less than the actual test voltage * Current, Why is that?
Answer: There are three types of power:
Active Power (P represents / unit W)
● Short press button to switch the backlight on and off.
● Press and hold for 3 seconds to enter the overload power setting.
-- Enter the overload power setting, default value is 4.4KW.
-- The highest bit flash, Short press the key corresponding to the val..
