overview
model td1200, a calibrator for leakage current testers, applied to calibrate passive leakage current testers (without isolated power supply) or active leakage current testers.
meet the requirements of jjg 843-2007 verification regulation of leakage current tester and sj/t 11383-2008 general specification of leakage current tester. the following tests are performed according to the requirements of regulations: leakage current error calibration, test voltage error calibration, input resistance measurement and input circuit time constant measurement.
applications
● calibrate active leakage current testers: use an intelligently controlled ac/dc current receiving source for calibration.
● calibrate universal leakage current testers (frequency is from 15 hz to 30 khz)
● calibrate medical leakage current testers (frequency is from 15 hz to 1 mhz)
features
● the current receiving source can track and control the changes of the power grid voltage to ensure the measurement accuracy.
● a built-in voltmeter can calibrate the error and distortion of the test voltage.
● measure the input resistance according to the requirements of regulations by the function of resistance measurement.
● measure the time constant of input circuit according to the requirements of regulations by the built-in frequency meter.
● high integration, abandons the traditional complex test methods, simple wiring and easy operation.
● good electrical protection to avoid damage caused by zeroing of the high resistance box.
