Saelig Introduces Affordable Low Compliance Voltage OR-01 OhmRanger-LCV™ Ohmmeter
OR-01 OhmRanger-LCV is a portable instrument for measuring the resistance of delicate components by using a very low stimulus voltage to avoid damaging the device being tested.
By: Saelig Co. Inc.
The maximum regulated stimulus voltage that can be supplied by OhmRanger-LCV can be 206mV or 380 mV to prevent harming a device under test. The maximum stimulus current is limited to approximately 30mA. A backlit 128 x 64 LCD display provides information about the resistance readings, which are displayed every 400mS and built from 160 averaged samples to eliminate 50/60 Hz line noise. Factory set calibration compensation is applied to both current and voltage, in order to give an accurate reading of resistance. A configurable audible signal informs the operator that a stable reading has been achieved.
A typical application example is that of D-Wave Systems, a quantum computing systems and services company that needed to measure the resistance of their sensitive Josephson junctions (a Quantum Computer's equivalent of a 'transistor')
A fully-isolated micro-USB interface is provided in the OhmRanger-LCV for device control (SCPI-format)
The OhmRanger-LCV is designed by UK-based AltoNovus, which specializes in designing compact, low power measurement products. Aimed at the quantum computing and nanostructures communities, including those focused on Transition Edge Sensors, nanowires, nanoscale meta materials, and Micro-Electro-
