Warranty

Please show your product certification when you need repair service or something wrong with items, it is effective show one and purchase invoice in together
1) Please contact with our company or repair service department when your clamp meter appear faults as soon as possible, don't delay your use and warranty period.
2) Our company provide warranty service for one year from the date of purchase.The company provides free warranty service after professional confirm the problem is not by user sabotage during the warranty period
3) Repair need charges (repairs components fee) more than the warranty period
4) All of the following will charge the cost of repair even in the warranty period.
⑴ Improper use or accidental disasters caused damage of components and circuit board burn
⑵ Non-professional personnel open shell, check and modification
⑶ Does not follow the instructions to operation caused problems

⑷ No maintenance and repair of the other company products
⑸ users offer the maintenance of postage and transportation fees

3.2.1 AC Current

-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.

3.2.2 DC voltage

- Min/ input voltage:0.5VV DC

- Input impedance:10MW

-Maximum/ input voltage:600V AC (Effective value)OR 600V DC

3.2.4 AC voltage

- Min/ input voltage:1.0V DC

-Input impedance:10MW

- Maximum/ input voltage:600V AC (Effective value)or 600V DC

- Frequency range:45Hz ~65Hz

3.2.5 Frequency

3.2.5.1 Through the V file:

- Range:40Hz ~ 1000Hz

- Input range:≥ 0.2A AC(Effective value)

3.2.5.2 Through A File (From Clamp)

- Range:40Hz ~ 1000Hz

- Input range:≥ 1.0V AC(Effective value)

3.2.6 Resistance

- 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.
