Overview of TD1880 High-precision Multifunction Calibrator

TD1880 is a wide-range, high-precision multifunctional calibrator. The instrument has built-in ultra-precision AC and DC voltage and current sources. It can output DC voltage, DC current, DC power and AC voltage, AC current, AC power, phase, frequency with excellent performance. It also has functions such as simulating resistance, capacitance, thermocouple and thermal resistor, and pulse output. It is a special equipment for calibrating six-and-a-half-digit and below digital multimeters and other precision electrical measuring instruments.

Applications of TD1880 High-precision Multifunction Calibrator

• Calibrate AC\DC electrical measuring instruments
  TD1880 high-precision multifunction calibrator is suitable for calibrating 6.5-digit and below digital multimeters, class 0.01 and below DC voltmeters and DC resistance meters, class 0.05 and below DC ammeters and AC voltmeters, class 0.1 and below AC ammeters, and class 0.01 and below frequency meters.

• Calibrate AC/DC power meters

  TD1880 high-precision multifunction calibrator's virtual power standard source consists of independent outputs of AC and DC voltage (DCV / ACV) and AC and DC current (DCI / ACI) with adjustable phase, which is suitable for calibrating conventional AC and DC power meters with U-I measurement method. So TD1880 high-precision multifunction calibrator is suitable for calibrating DC power meters of class 0.05 and below, active power meters of class 0.1 and below, reactive power meters, apparent power meters, power frequency phase meters, power factor meters, and power analyzers.
  

• Calibrate capacitance meters (optional)

  With capacitance output 1.1 nF ~ 30 mF, 0 Hz ~ 3 kHz, TD1880 high-precision multifunction calibrator is suitable for calibrating capacitance meters and capacitance testers of class 1 and below.

• Calibrate temperature meters(optional)

  TD1880 high-precision multifunction calibrator is applicable to calibrate the corresponding thermocouple temperature meters and thermal resistance temperature meters of the above types.

• Calibrate clamp ammeter (optional)

  Users can choose TD1020 current coil (50 turns), pass 20 A AC and DC standard current, and achieve equivalent current output of up to 1000 At, which is suitable for calibrating clamp ammeters or current clamps with lower accuracy of lclass 1 and below. 

  If you need to calibrate a clamp ammeter with higher accuracy, you can choose clamp ammeter calibration device products such as TD1050 from Tunkia.

Characteristics of TD1880 high-precision multifunction calibrator

• Wide output range

  The multifunctional standard source output range of TD1880 covers the working range of electrical measuring instruments such as six-and-a-half-digit digital multimeters and below, and can be directly calibrated using the standard source method.

• High stability and accuracy

  The power output of TD1880 is extremely stable, with a DC voltage stability of up to 2ppm/24h.

• 4-terminals Simulated DC resistance

  TD1880 has two-wire and four-wire resistance connection modes. When calibrating low-mid-value resistance, the four-wire connection mode can effectively eliminate the measurement error caused by the test lead resistance and improve the measurement accuracy.

  Compared with the traditional standard physical resistance box, TD1880 uses analog resistance output and has the following advantages:☑ Continuously adjustable, with better adjustment fineness and sensitivity
  

  ☑ Continuously adjustable, better adjustment fineness, higher sensitivity

  ☑ Smaller size, lighter weight, easier integration

  ☑ No influence of switching error, residual resistance error and contact resistance error.

  
  

  

• Safety protection function

  TD1880 high precision multifunction calibrator has a complete safety circuit protection function. When the self-protection is triggered, the device will alarm and pop up an alarm prompt on the screen interface. After the user checks and confirms and eliminates the fault, it only takes one button to reset the protection to return to normal.
  

  Accidental voltage or current applied to the output of the multifunction calibrator may cause serious damage to the built-in components of the instrument, resulting in expensive repair costs and a decrease in the use rate of the instrument during the repair period.
