3.2.1 AC Current
| Range | Resolution | Accuracy |
| 6A | 0.001A | ±(3.0% + 20) |
| 60A | 0.01A | ±(2.5% + 8) |
| 400A | 0.1A | ±(2.5% + 10) |
- Min input current:0.02A AC
- Max input:400A AC
- Frequency:45Hz ~65Hz
- When ac current is measured, the meter automatically opens an
internal low-pass filter to filter out high-frequency current.

| 10MW | 0.1MW |
- Overload protection:600V DC or AC(Effective value)
Current measurement
1) Hold the trigger, open the pliers, and clamp a wire of the
circuit under test in the pliers.
2) When the measured signal is greater than or equal to 0.02A, the
main screen of the instrument will display the measured current
value, and the secondary screen will display the frequency value of
the current (note: the meter will only display the frequency value
if the current is greater than or equal to 0.02A)
Noted
1) The correct measurement results cannot be obtained by clamping
two or more wires of the circuit under test at the same time.
2) In order to obtain accurate readings, the conductor under test
should be placed as far as possible in the center of the current
clamp.
3) Represents the maximum input ac current of 400 A.
4) Please hold the clamp head when the current measurement machine
to open the clamp head and nose pliers head clip conductor under
test, and then slowly let go of the trigger, until the clamp head
closed completely, please be sure to test whether the conductor is
picking up in the middle of the tong head, not in the tong head
center will produce additional error, clamp table can only measure
electrical conductor, a conductor if two or more current is
measured at the same time, the measuring reading will be wrong.
