A current coil is a component made by winding a conductive wire through which electric current flows. While TD1020 is a series of multi-turn current coils designed based on the ampere-turn equivalence principle. It is used together with the TD18 series standard current sources to calibrate clamp meters with accuracy class 1 or lower.
How to Calibrate Clamp Meter-Single-Turn Method1. Single-Turn MethodTD1000 and TD1500 Clamp Meter Calibration Devices are used to calibrate multi-functional clamp meters. They have the functions of AC and DC high current standard source, AC and DC voltage standard source and resistance standard sour
Using the TUNKIA’s TD18 series Multi-function Calibrator with the TD1020 Current Coil, the user can choose the TD1020 Current Coil (50 turns) and pass in the AC and DC standard current of 20 A to achieve an equivalent current output of up to 1000 At, which is suitable for calibrating lower accuracy clamp meter or current clips of accuracy 1% and below.
