TM7900 is a high-precision Calibrator for Flux Meter , which generates magnetic flux by a built-in high-precision Volt-second Generator (1Vs=1Wb). It calibrates flux-meters by comparing indicating value of the flux-meter with the value it generates. Compared with Mutual Inductance method, Volt-second method is featured with easier to use, better precision and traceability, it is applied for calibrate digital flux-meter and electrical integrator.
