Product Description

 

TM7900 Precision Volt-second Generator For Flux Meter Calibration

1. Summary

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.
 

2. Features

1. Accuracy Class: 0.005, 0.01, 0.02 or 0.05.
2. Built-in high-precision voltage source and timer.
3. Generate magnetic flux by integrating voltage and time. 
4. Calculate and output voltage and time by setting magnetic flux value.
5. Quick calibration in several seconds. 
6. Unit switch: mWb, Wb, Vs, mVs, Mx.
7. Support setting interior resistance and wire resistance.
8. Eliminate interior resistance's influence by compensation.
9. Large LCD screen and press-key.

 

3. Application

☆ Fast calibration of Digital Fluxmeter
