Purpose and Features
The 030-Q Type Clamp Meter Calibrator (hereinafter referredtoas the calibrator)features a 5.5-digit LCD screen digitaldisplay of output values,and can simultaneouslydisplayparameters such as the error of the device under test,errorcorrection value,percentage of output quantity,full scale value of the device undertest,step value,and frequency for both AC and DC voltage and current calibrationsources.Additionally,it is equipped with a 22-range standard resistor set for convenientcalibration of multimeter resistance ranges.An RS232 interface is available forautomatic data processing functions.
The verification instrument adopts advanced technologies such as amplitudestabilization,power amplification,and protection,ensuring good stability,high
precision,wide range,fine grading,and safety and reliability.The amplitude adjustmentuses a combination of digital key control and encoder adjustment,making control flexibleand responsive,meeting different needs for constant value output and continuous
adjustment,making it more convenient and efficient to use.It is suitable for verifyingand calibrating four-and-a-half-digit digital multimeters,various current and voltagemeters below 0.2 level,and multimeters of corresponding accuracy levels.It can also beused as a high-stability test power supply,in conjunction with a high-grade standardmeter,to calibrate current and voltage meters above 0.2 level.Widely used in qualityinspection,metrology,and instrument maintenance in industrial and miningenterprises,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,allowing 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.
