Introduction

  • TD1350, a reference AC/DC ammeter with an ultra-wide current measurement range. The accuracy is up to class 0.005% and 0.01%, and the measurement accuracy of DC current above 1 A and AC current is much better than 8½ digital meters.

  • Instead of 8½ digital meters, TD1350 is applied to measure aperiodic signals (e.g. ripple) or complex waveform signals and calibrate AC/DC current sources (e.g. Fluke 5500A/5520A) and multimeter calibrators which the accuracy classes are 0.02% and below.


Features

  • Wide range of direct current measurement: a pair of terminals can be used to measure the DC current of 10 μA ~ 120A, which solves the top problem of automatic range switching of ultra-wide range DC current.

  • Current expansion measurement: it is equipped with a special measurement interface for the sensor, which can be connected with a through current sensor to expand the measurement range to 500 A, 1 kA, etc.

  • High Reliability: Not easy to damage when overloaded.

  • Other Measurements: Ripple, harmonic, distortion, waveform monitoring, etc.

  • Multiple measurement modes: DC, AC, DC + AC three modes, fundamental frequency: 10 Hz ~ 1 kHz, and measure periodic or aperiodic signals.

  • Excellent Human-computer Interaction: LCD touch screen, more intuitive of value display and easier operation. it is equipped with RS232, USB, RJ45 interfaces, which is convenient to set up a full-automatic measurement system.
