Key Features:
- Faibles tensions de stimulation, sélectionnables entre environ 380 mV et 205 mV.
- Mesures précises de >100M à 10Ω
- Un écran LCD 128 x 64 fournit une multitude d'informations sur vos lectures de résistance
- Lectures toutes les 400 ms, constituées de 160 échantillons et moyennées pour éliminer le bruit du secteur (50 Hz et 60 Hz).
- L'affichage SNR indique le niveau de bruit sur le signal
L'OhmRanger-LCV™ est un voltmètre/ohmmètre à faible conformité, conçu pour maintenir la tension de test en dessous de 400 mV. Il peut mesurer une résistance de 10 Ω à 100 MΩ.
Le ΩhmRanger-LCV™ est essentiel pour mesurer la résistance d'un composant délicat. La plupart des ohmmètres appliquent une tension de stimulation au dispositif testé (DUT) de 3 à 10 V. Cette tension de stimulation peut détruire ce que vous essayez d'étudier !
Le ΩhmRanger-LCV™ est fourni dans un étui de transport robuste et protecteur pour le garder en sécurité.
Features*
Low stimulus voltages, selectable between approx 380mV or approx 205mV.
- Stimulus voltage at the output terminal is limited by the maximum current supply of approx 20mA.
- Accurate readings from >100M to 10 Ohms.
- A 128 x 64 LCD display gives a wealth of information about your Resistance readings.
- A large display shows MΩ, KΩ, and Ω, all on one line.
- Readings every 400mS, built up from 160 samples and averaged to tune out mains noise (both 50 Hz and 60 Hz).
- Fully isolated USB Interface for device control and readings export.
- SNR display indicates noise level on signal.
- On-screen confirmation of stimulus voltage.
- Range Bar movement after every reading shows that ΩhmRanger-LCV™ is operating correctly.
- Range Coverage Bar shows the ranges covered during the measurement.
- User-configurable Auto Power-off timer.
- ΩhmRanger-LCV™ is highly portable with dimensions of 148 x 90 x 30mm.
- 2 x AA batteries should give around 150 hours of operation.

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."
