Key Features:
- Low stimulus voltages, selectable between approx 380mV and 205mV.
- Accurate readings from >100M to 10Ω
- A 128 x 64 LCD display gives a wealth of information about your Resistance readings
- Readings every 400mS, built up from 160 samples and averaged to tune out mains noise (both 50 Hz and 60 Hz).
- SNR display indicates noise level on signal
The OhmRanger-LCV™ is a low-compliance Voltage/Ohmmeter, designed to keep the test voltage below 400mV. It can measure resistance from 10Ω to 100MΩ.
The ΩhmRanger-LCV™ is essential when measuring the resistance of a component that is delicate. Most ohmmeters will apply a stimulus voltage to the Device Under Test (DUT) of 3-10V. This stimulus voltage may destroy what you are trying to investigate!
The ΩhmRanger-LCV™ is supplied in a Tough, protective carry case to keep it safe.

A Real Customer Need - Met
The Josephson Junction is the Quantum Computer's equivalent of a 'transistor'. Although it is delicate, the ΩhmRanger-LCV™ can measure its resistance without risking its integrity.
D-Wave Systems, the Quantum Computing systems and services company, needs to measure the resistance of their Josephson Junctions. Working closely, a prototype Low Compliance Voltage Ohmmeter was quickly developed and the design was subsequently refined through testing and practical lab use. The result is the ΩhmRanger-LCV™, the low compliance voltage ohmmeter, scheduled for general release in October 2021.
On completion of test and evaluation, D-Wave commented;
"The AltoNovus ΩhmRanger-LCV turned an error-prone measurement into a simple measurement ..... a valuable addition to our work building quantum computers."
"The fundamental element in D-Wave's unique product is a Josephson Junction - this is the "transistor" in a quantum computer. In practice, these devices are extremely sensitive and easy to damage. Measuring the resistance with a standard multimeter will destroy the Josephson Junction.
The AltoNovus ΩhmRangerLCV turned an error-prone measurement into a simple measurement. The low compliance voltage ensures that the device under test never sees a stimulus above 400mV. The ΩhmRanger-LCV measures a wide resistance range, and the upper end of the range (400MOhm) ΩhmRanger-LCV makes it simple. This, in addition to a nice group of features, including a quality metric - signal-to-noise, continual indication of the stimulus voltage, and a cute mode for measuring microscopic pins while looking through a microscope, makes this device a valuable addition to our work building quantum computers."
