Introduction

  • TD1310, a high-precision AC/DC standard instrument, can measure AC/DC voltage, current and small signal voltage. The best accuracy is 0.005% (DC) and 0.01% (AC).

  • The instrument is also a high-level AC/DC standard power / energy meter, and the best measurement accuracy is 0.01% (DC) and 0.02% (AC).

l  The application of this instrument is very wide, and it can directly verify or calibrate equipment such as AC/ DC voltage sources, current sources, power sources, and multi-function calibrators.

  • It can also be used as a standard meter with test power supply to calibrate voltmeter, ammeter, resistance meter, power meter, frequency meter, phase meter, transmitter, sensor and other measuring instruments.

  • In the field of electric energy measurement, the instrument can be used as a high-level electric energy standard meter to check AC/DC electric energy meter verification device, standard electric energy meter, charger tester and so on.

  • The measurement mode of DC + AC is especially suitable for the verification and calibration of DC energy meter verification device with ripple detection function.


Features

l  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.

  • The interface can supply power for the sensor and measure the secondary signal at the same time. The primary current can be displayed directly, by setting the ratio of the sensor on the instrument.

  • Small signal voltage measurement: it can withstand the overload signal of 100V peak voltage. It is suitable for testing indirect access watt hour meter verification device. It can also be connected with shunt or I / V conversion standard to measure large current.

  • Statistics and Analysis of Data: Calculate the electrical parameters such as the maximum, minimum, average, difference, standard deviation, etc.

  • Multiple measurement modes: DC, AC, DC + AC three modes, fundamental frequency: 40Hz ~ 1kHz, and measure 2 ~ 63th harmonic and DC ripple.

  • High reliability of the instrument: complete electrical isolation between voltage and current measuring circuits.

  • When measuring real load power, the current measurement circuit can be placed on the high or low side of the voltage circuit.

  • Electric Energy Metering: Standard I/O pulse interfaces, used for building a standard for high-class AC/DC electric energy metering.

  • 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.
