LOW CURRENT/HIGH RESISTANCE
614 Electrometer
For most new applications, the Model 6514 (page A-73) offers
better performance than the 614, plus IEEE-488 and RS-232
interfaces at a similar cost.
Sensitive Performer
The 614 performs four functions: current, resistance, voltage,
and charge measurements. It is capable of detecting currents
as low as 10
more than 5×1013Ω input impedance on the voltage ranges,
and can detect charge over a range of 10
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 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 current suppress
feature allows background currents 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.

617, 617-HIQ Electrometer/Source
For most new applications, our Model 6517A (page A-77)
offers better performance than the 617 at a similar cost.
The new Model 6514 offers similar functionality and
includes the high charge measurement capabilities of the
617-HIQ.
The Model 617 performs four functions: current, resistance, voltage, and charge measuremnets. It is capable of
detecting currents from 1
up to 5×10
impedance on voltage measurements from 10µV to 200 V
and can detect charge over a range of 10
addition to standard resistance functions using constant
current, the 617’s variable voltage source can supply from
50mV to 102V, which can be applied to a resistance and the
resulting current or resistance displayed.
The 617’s built-in IEEE-488 interface makes all controls
programmable. The built-in V-Ω GUARD switch lets you
drive the inner shield of the triaxial input cable at guard
voltage, minimizing leakage current and time constants.
100-point data storage is also built in, with Min/Max readings available from front panel or bus.
For measurements of charge as high as 20µC, the 617-HIQ
version offers three higher charge ranges. These higher
ranges have proven useful on Faraday cup measurements
and other static charge applications including photocopy
research and development.
