SafeRanging

PocketPico instruments offers a unique patent pending technology called SafeRanging — a continuous ranging feature that is superior to the conventional relay based auto-ranging technology integrated into other picoammeters. SafeRanging allows our instruments to be a smaller, safer, more convenient instrument.

SafeRanging makes use of a logarithmic current measurement scale across several decades of input currents with no need to set a measurement range. This simplifies your testing and eliminates the problems of range selection and auto-range changing present in other picoammeters.

With our picoammeters there’s no need to estimate the range to begin taking measurements, no need to define a specific range or trying to work around the problem, and no need for expensive protection hardware. Life in the lab is simpler, faster and more convenient.

Problems with Auto-Ranging

When auto-ranging was introduced, it decreased testing time by enabling automation. However, this breakthrough came with some drawbacks, most notably an increased risk injected current due to transient voltages. The PocketPico’s SafeRanging technology solves this issue.

Other manufacturers warn that their picoammeters cannot maintain the voltage burden specification when switching ranges, and so the picoammeter becomes a current-limited voltage source until it re-attains equilibrium. This results in a current surge into your setup that can result in a voltage spike up to hundreds of volts.
