overview
model td6610, a field calibrator for ammeters and voltmeters of electric welders. it can measure the dc high voltage up to 550 v, and the dc high current up to 3300 a. the optional accuracy classes are 0.05 and 0.1. the ammeters and voltmeters of electric welders can be directly calibrated in field without dismantling the electric welders.
meet the requirement of jjg 1587-2016 calibration specification for multimeters and jjg 124-2005 verification regulation of amperemeters, voltmeters, wattmeters and ohmmeters.
application
● calibrate the electric measuring instruments for electric welders in field or laboratory with adjustable resistive loading box of high power.
● calibrate ac voltmeters and ammeters (class 0.5 and below)
● calibrate dc voltmeters and ammeters (class 0.5 and below)
● calibrate ac and dc standard sources (class 0.5 and below)
features
● dc and ac measurement modes for voltage and current, and the ac frequency is from 45 hz to 65 hz (customized to 1 khz)
● quickly capture the rapid changes of current by the built-in broadband ac-dc comparator.
● directly connect to the measuring circuit of the instruments of electric welders, and the artificial arc is used as the load for the field calibration.
● no mechanical contacts such as relays in the current test loop, strong overload capacity and high reliability.
● good electrical isolation and protection for the measurement loop make a high safety.
● the internal resistance of the voltage and current inputs has minimal influence on the measuring circuit and makes the measurement more stable and accurate.
● record the maximum and minimum of the measured parameters, and calculate the average and standard deviation over the sampling period.
● draw the trend curve of the measured parameters, and display the stability of the measured parameters by the histogram.
● large lcd touch screen, more intuitive of value display and easier operation.
● small size, light weight and good protection make it suitable for field operation.
