TD1050A Calibration Device Easy Traceability For AC DC Clamp Meter

TD1050A Calibration Device for Clamp Meter

Introduction

TD1050A, a calibration device for clamp ammeters. The optional accuracy are 0.02% and 0.05%.
The device calibrates the AC/DC clamp ammeters by single coil with high accuracy and easy traceability, and has the functions of AC/DC current output, resistance simulation, frequency/phase adjustment, power detection.
Meet the requirements of JJF 1075-2015 Calibration Specification for Clamp Ammeter. (Tunkia is involved in drafting)

Features

Calibrate AC/DC clamp ammeters by single coil: The AC/DC current source connect to a single coil semi-circular copper ring with a diameter of 1m, can directly output AC/DC high current up to 2200 A (or 1100 A). Suitable for calibrating AC/DC clamp ammeters with high accuracy.
Place the clamp meter in the center of the copper ring when calibrating. The diameter of the copper bar in the center position is smaller than the other positions, which is convenient for the access of small size clamp meters.
Easy to open the copper ring, and thread a standard current transformer or I-V converter into the ring for calibrating the device itself regularly.
Reserved terminals for high current, to provide current for the calibration of DC shunts.
Value Adjustment Method: Fixed-point, rotary encoder, and step.
Frequency and Phase (Option): The AC output frequency and the phase between voltage and current is variable.
Power Output (Option): Test DC power, active power, reactive power, apparent power and power factor.
Proprietary Software (Option): Support the calibration of the checked ammeters by semi-automatic or full-automatic, data management and report export.
