The Keithley 614 Electrometer performs four functions: cur, resistance, voltage, and charge measurements. It is capable of detecting curs as low as 10–14A and resistances up to 2´1011½. It provides more than 5´1013½ input impedance on the voltage ranges, and can detect charge over a range of 10–14 to 2´10–8C. It is appropriate for a wide range of applications in component and circuit testing as well as in research and student laboratories.Battery/Line:For isolation from AC line interference, the 614 features a built-in, rechargeable lead-acid battery pack. The pack provides more than 10 hours of off-line operation, automatically recharges when the power line is plugged in, and automatically cuts in should line power be interrupted.Flexible and Convenient:The Keithley 614 rear panel includes two analog outputs: a 2V output for recorders and a preamp output for use as a driven guard with the 6167 guarded input adapter. The cur suppress feature allows background curs to be zeroed out at the touch of a button. Durable construction and a full range of capabilities assure a long and cost-effective life cycle.Specifications of the Keithley 614 Electrometer include:
