The Keithley 5½-digit 6517B Electrometer / High Resistance Meter offers state-of-the-art accuracy and sensitivity specifications and has various features that simplify measuring high resistances and the resistivity of insulating materials. With faster reading rates of up to 425 readings/ second, the Keithley 6517B offers a quick, easy way to measure low-level currents.
The Keithley 6517B is an updated version, replacing the earlier Model Keithley 6517A. Software applications created for the Keithley 6517A using SCPI commands can run without modifications on the Keithley 6517B. However, the newer Keithley 6517B does offer some useful enhancements to the earlier design. Its internal battery-backed memory buffer can now store up to 50,000 readings, allowing users to log test results for longer periods and to store more data associated with those readings. The new model also provides faster reading rates to the internal buffer (up to 425 readings/second) and to external memory via the IEEE bus (up to 400 readings/second). Several connector modifications have been incorporated to address modern connectivity and safety requirements.
