TM7900 is a high-precision Calibration Apparatus 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-meters and electrical integrators.
– Accuracy Class: 0.005, 0.01, 0.02 or 0.05.
– Built-in high-precision voltage source and timer.
– Generate magnetic flux by integrating voltage and time.
– Calculate and output voltage and time by setting magnetic flux value.
– Quick calibration in several seconds.
– Unit switch: mWb, Wb, Vs, mVs, Mx.
– Support setting interior resistance and wire resistance.
– Eliminate interior resistance’s influence by compensation.
– Large LCD screen and press-key.
