Keithley 6485/E Bench Digital Picoammeter, 20mA ac Max, 20mA dc Max, Мультиметр

Keithley 6485 Picoammeter

Measuring low DC currents may demand more than a DMM can deliver. Electrometers measure low currents but have costly circuitry and functions. The Keithley 6485 5-digit Picoammeter offers sensitive current measurement instrumentation with enhanced speed and robust design. With eight current measurement ranges and high speed autoranging, it measures currents from 20fA to 20mA. The 6485 makes picoamp-level measurements affordable to most laboratories and production floors.

Features and Benefits

• Scaled voltage analog output. This output allows the Model 6485 to transmit measurement results to devices like DMMs, data acquisition boards, oscilloscopes, or strip chart recorders.
• 220V overload protection. This high overload protection and a robust design let the Model 6485 withstand abusive overflows.
• One-touch front panel design. Functions can be configured easily with the push of a button, without complicated function menus.
• Built-in Trigger Link interface. The Trigger Link interface simplifies synchronizing the Model6485 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.
• RS-232 and IEEE-488 interfaces. These interfaces make it easy to integrate the Model 6485 into automated test and measurement systems.
• Display on/off switch. For research on light-sensitive components, such as measuring the dark currents of photodiodes, the front panel display can be switched off to avoid introducing light that could significantly reduce the accuracy of the results.
• REL and LOG functions. The Model 6485 can make relative readings with respect to a baseline value or display the logarithm of the absolute value of the measured current.
• Resistance calculations. The Model 6485 can calculate resistance by dividing an externally sourced voltage value by the measured current.
• Rear panel BNC inputs. Inexpensive, easy-to-use BNC cables can be employed, rather than more expensive triax cables.
