3.2 Technical indicators
Environment temperature:23±5℃ Relative humidity:<75%
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.

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.
