td1220 calibrator for high voltage and value dc resistors

专用于检定直流高压高值电阻器、高压电阻箱、直流高压表


阻值范围:10 ω ~ 10 tω

电压范围: 0 ~ 10 kv


overview

model td1220, an intelligent calibrator for high voltage and value dc resistors, high voltage resistance boxes and high voltage dc meters. the resistance range is from 10 ω to 10 tω, and the voltage output range is from 0 to 10 kv. applied to calibrate the high resistance box with class 0.05 and below.

meet the requirements of jjg 1072-2011 verification regulation of high voltage and value d.c. resistors and dl/t 979-2005 verification regulation of high voltage d.c. resistance box.

applications

● calibrate high voltage and value dc resistors and resistance boxes, high voltage dc meters, milliammeters and voltage dividers.

● calibrate the insulation resistance tester calibration devices

● calibrate the megger calibrators

features

 constant current (cc) mode: the stability of current output is 0.01 %/h, applied to measure low resistance. the maximum voltage on this mode is 1050 v, can prevent high voltage from damaging the low resistance dut.

● constant voltage (cv) mode: the stability of current output is 0.005 %/h, applied to measure high resistance. the current output of this mode is limited to 3 ma or less, can protect the measured resistance and the calibrator itself.

● simultaneously output dc voltage or current and measure resistance, the accuracy of calibrating high voltage dc meters is up to 3×10-4.

● the measurement uncertainty from 100 ω to 100 mω is better than 2×10-4, the measurement accuracy of 10 tω is still up to ±2 %.

● all-digital button output mode, which is better than the mode of rotary shirt switch, makes the error calculation much simpler.

● good electrical isolation and protection ensure high safety and reliability.

● large lcd touch screen, more intuitive of value display and easier operation.

 proprietary software (option): support the calibration of the checked meters by semi-automatic or full-automatic, data management and report export.
