Functional features and applications of Keithley 6517B electrometer

吉时利5½位显示的6517B提供的精度和灵敏度指标是高于其他同类型仪表。它丰富的功能使测量高阻和绝缘材料电阻率变得简单。 6517B具有425读数/秒的读数率，比同类型的静电计显著的快，可以提供快速、简易的方式测量弱电流。

Model 6517B is an updated version, replacing the earlier model 6517A (introduced in 1996). Model 6517A application software can run on Model 6517B without any modification using SCPI language commands. However, Model 6517B offers some useful improvements and upgrades over Model 6517A. Its internal backup battery memory buffer can now store up to 50,000 readings, allowing users to record test results for longer periods of time and store more data. and readings. The new model also provides higher reading rates to the internal buffer (reading rates up to 425 readings/second) and to external memory via the IEEE bus (reading rates up to 400 readings/second). Several connector modifications have been included to address modern connectivity and security requirements.
