控扫描仪

进口工业网的低热监控扫描仪设计用于提高高电阻测量的精确度。不带监控装置的Data Proof扫描仪在测量时百万分之几十会有大约1012 的疏漏。监控的实行可以较少10 G水平误差的发生。

Unguarded, the Data Proof scanners have leakages of about 1012 which can cause errors of a few tenths of a PPM when measuring 1 M. Guarding greatly reduces the errors allowing excellent accuracy up to the 10 G level.

电位和电流附近的高度监控会导致每个电阻的高终端，低级的监控会导致电阻的低终端。监控屏蔽的开关与电流和电位线路一起。监控通过电阻的屏蔽电缆进行，通过扫描仪到达输出电缆。

The high guard surrounds the potential and current leads to the high end of each resistor, and a separate low guard surrounds the leads to the low end of the resistor. The guard shields are switched along with the current and potential lines. The guard is carried through shielded cables from the resistor, through the scanner and to the output cables.
