This instrument adopts the high-performance single-crystal microcomputer chip imported from ST Microelectronics, combined with the American “Microchip” high-resolution A/D conversion chip as the measurement control core, and the precise 1.000KHZ AC positive current synthesized by the phase-locked loop is used as measurement signal source apply on the tested element. The generated weak voltage drop signal is processed by high-precision operational amplifier, and the corresponding internal resistance value is analyzed by intelligent digital filter. Finally, it is displayed on large screen dot matrix LCD.

The instrument has the advantages of high precision, automatic file selection, automatic polarity discrimination, fast measurement and wide measurement range.

Features:

  • Microchip Technology high-resolution 18-bit AD conversion chip to ensure accurate measurement;
  • Double 5-digit display, the highest resolution value of measurement is 0.1μΩ/0.1mv, Fine and high precision;
  • Automatic multi-unit switching, covering a wide range of measurement needs;
  • Automatic polarity judgment and display, no need to distinguish battery polarity;
  • Balanced input Kelvin four-wire measuring probe, high anti-interference structure;
  • 1KHZ AC current measurement method, high accuracy;
  • Suitable for various battery/pack measurements below 100V;
  • Equipped with computer serial connection terminal, expanded instrument measurement and analysis function.

Scope Of Use

1. It can measure internal resistance and voltage of ternary lithium, lithium iron phosphate, lead acid, lithium ion, lithium polymer, alkaline, dry battery, nickel-metal hydride, nickel-cadmium, and button batteries, etc. Quickly screen and match all kinds of batteries and detect battery performance.

2. R&D and quality testing for manufacturers of lithium batteries, nickel batteries, polymer soft-pack lithium batteries and battery packs. Purchased batteries quality and maintenance testing for stores.
