It will give a beep sound which confirms that the voltage is flowing in the wire. It will not show how much voltage is flowing it will just sense and give you a beep sound. For measuring voltage you have to use the lead set and put the dial on to voltage range **Q: Does it comes with valid calibration certificate?. What is the warranty period?** A: Sir, It comes with 1 year calibration certificate with the meter **Q: Confirm that it can measure DC current in clamp mode without having to use multimeter leads?** A: Yes it can measure DC Current through clamp, without using multimeter leads ## Customer Reviews ### ⭐⭐⭐⭐⭐ Honest review about Sigma 313A PTRMS *by A***P on 8 October 2023* After buying and testing all the features found working very well.
