Benefits |
|
Low cost
|
With a price that's comparable to a general purpose DMM, the Model 6482, 6485, or 6487 makes picoamp-level measurements affordable for virtually any laboratory or production floor
|
|
Low voltage burden
|
The low voltage burden makes the picoammeter function much more like an ideal ammeter than a DMM, so it can make current measurements with high accuracy, even in circuits with very low source voltages
|
|
Scaled voltage analog output
|
This output allows the picoammeter to transmit measurement results to devices like DMMs, data acquisition systems, oscilloscopes, or strip chart recorders
|
|
Rear panel inputs
|
Inexpensive, easy-to-use BNC cables can be employed on the Model 6485. Triax connectivity on the Model 6487 allows the instrument to be used in floating operation, up to 500V
|
|
Built-in Trigger Link Interface
|
The Trigger Link interface simplifies synchronizing the picoammeter with other instruments and voltage sources. This interface combines six independent selectable trigger lines on a single connector for simple, direct control over all instruments in a system
|
|
One-touch front panel design
|
Functions can be configured easily with the push of a button, without complicated function menus
