Purpose and Features
◆The 030-3A Multifunction Calibration Instrument (hereinafter referred to as the verifier)features a five-and-a-half-digit LCD screen digital display of output values,and can simultaneously display parameters such as the test meter error,error correction value,output quantity percentage,test meter full scale value,step value,and frequency forboth AC and DC voltage and current calibration sources.Additionally,it is equipped witha 22-range standard resistor group for convenient calibration of multimeter resistanceranges.An RS232 interface is available for automatic data processing functions.
◆ The verifier adopts advanced technologies such as amplitude stabilization,poweramplification,and protection,making it highly stable,precise,wide-ranging,finely gradedsafe,and reliable.The amplitude adjustment uses a combination of digital key control andencoder adjustment,making control flexible and responsive,meeting different needs for fixedvalue output and continuous adjustment,and making it more convenient and efficient to use.Itis suitable for verifying and calibrating 4.5-digit digital multimeters,various current andvoltage meters below 0.2 level,and multimeters of corresponding accuracy levels.It can alsobe used as a high-stability test power supply,in conjunction with high-grade standard meters,to calibrate current and voltage meters above 0.2 level.Widely used in quality inspection,metrology,and instrument maintenance in industrial and mining enterprises,research institutes,railways,electric power,and other units.
Main Functions
◆ 5 and a half-digit LCD digital display output quantity,simultaneously displaying range,indication error of the test meter r A and reference error r m,correction value,output quantitypercentage,full scale value of the test meter,frequency,and step value.It displays the output quantity in both actual value and percentage simultaneously,al lowing for immediate readingof the test instrument's error,saving time and effort.
◆ The regulator uses a keyboard to control the increase and decrease of the output quantity.The regulator is equipped with both a keyboard and an encoder.The initial cursor position is at the last digit,and it can be moved to any digit except the first one using the left and right arrow keys.The encoder adjusts the value according to the cursor position.The keyboard control quantities are divided into 100%N,10%/N,1%/N,0.1%/N,0.01%/N(N is 4,5,6,10,15).
◆ AC and DC voltage output range:0～250mV～1V～2.5V～5V~10V～25V～50V～100V～250V～500V～1000V,with a maximum voltage output of 1100V.
