DC current and LCR meter signal level is very difficult if not impossible. Until now, DC Bias supplies were restricted to a particular manufacturer's LCR model number in an attempt to minimize these errors. DC1000A User Manual (98-102 issue 3)
11.2.3. The Solution With the DC1000A's correction circuit, these errors are essentially eliminated by the use of an inductor placed inside an AC control loop. A sense winding on the inductor produces a voltage proportional to the AC voltage across it.
Page 76
The below graph demonstrates the massive reduction in error current, by comparing the error current caused by the DC1000A both with and without the correction circuit operating. Fig 4 Effect of DC1000A correction circuit on error current.
3. Now open and short compensation can be applied by the LCR meter as usual to make measurements free from all stray effects. 4. The DC1000A requires no special connection to the LCR meter, or knowledge of its settings, making it suitable for use with any LCR meter.
