TRACOR Keithley 614 Electrometer

TRACOR Keithley 614 Electrometer

**This unit has been tested to specifications. Accessory included. Has slight cosmetic blemishes from normal use. See photos for further details. 

• Includes: Model: 6011 Input Lead Cable: Input Lead is a shield low noise triaxial cable Terminated with alligator clips. This cable mates directly with the model:614 input.

The 614 Digital Electrometer is a 4 1/2 digit multimeter designed with speed and simplicity of use. It features four functions: current, resistance, voltage and charge measurement. It is capable of detecting currents as low as 10 -14 A and resistances up to 2 x 10E+11 ohms. It provides more than 5x10E+13 ohms input impedance on the voltage ranges and can detect charge over a range of 10E-14 to 2 x 10E-08C. Voltage ranges are 0.2 V to 20 V in 3 ranges with accuracies to 0.08%. Current ranges from 20 pA to 2000 µA in 9 ranges with accuracies from 1.5 to 0.3%. Resistance ranges are from 2 kohms to 200 Gohms in 9 ranges with accuracies from 0.5 to 2%.

The Model 614 is an electrometer with 10-14 A sensitivity, and an input current less than 60fA at 23'C. Voltage sensitivity is 10uV to 20Vwith an input impedance of greater than 50T(5x10/13). Resistance sensitivity of the model 614 is from 1 to 2x10/11 using the constant current technique. Charge sensitivity (nC)is from 10fC (10-14 Coulombs) to 20nC(2x10-8 Coulombs). 

Features

• 4 1/2-digit display with appropiated decimal point
• 2V Analog Output-The 2V Analog Output provides an analog signal with a scale of 2V for full range at the display. The output impedance is 10K
• Preamp Output that can be used as guards in the volts and resistance functions and as an inverting output in the current and charge functions.
• Current Suppress wich is available in the current mode, allows correction for input offset currents on any given rang. Does not affect accuracy or drift.
• Each range has the following: Automatic polarity  operation, minus sign displayed. Effective input Overload protection. Over range indication (flashing 0000). Decimal point positioned by range push button.
• Battery Pack standard
• Line Power can also be used. Switch over from battery power to line power automatic
• Volts Zero sets: zero on the .2V range and need not be readjusted on the other ranges.
