1-2 Getting Started Model 6487 Reference Manual
Introduction
The Model 6487 is a high resolution bus-programmable (RS-232 and IEEE-488)
picoammeter. The Model 6487 has the following current measurement ranges: 8 ranges,
from 20mA down to the 2nA range. The Model 6487 also has a built-in ±500V DC voltage
source and an ohms function that includes an alternating voltage mode for enhanced high
resistance measurement accuracy.
