TD1860 Multi-Product Calibrator

Introduction

• TD1860 is a wide-range, multi-value, high-precision multi-function calibrator. It can accurately output AC/DC voltage, current, power, resistance, and has both frequency and phase adjustment, pulse output, and transmitter secondary signal measurement functions. It is suitable for calibrating DC current instruments of 0.05% and below, AC measuring instruments and multimeters of 0.2% and below.
