Key Features
- Niedrige Reizspannungen, wählbar zwischen ca. 380mV und 205mV.
- Genaue Messwerte von >100M bis 10Ω
- Ein 128 x 64 LCD-Display liefert eine Fülle von Informationen über Ihre Widerstandswerte
- Messwerte alle 400 ms, aufgebaut aus 160 Proben und gemittelt, um Netzrauschen (sowohl 50 Hz als auch 60 Hz) auszublenden.
- Die SNR-Anzeige zeigt den Rauschpegel des Signals an
Overview
Der OhmRanger-LCV™ ist ein Spannungs-/Ohmmeter mit geringer Compliance, das die Prüfspannung unter 400 mV hält. Es kann Widerstände von 10 Ω bis 100 MΩ messen.
Der ΩhmRanger-LCV™ ist unverzichtbar, wenn Sie den Widerstand einer empfindlichen Komponente messen. Die meisten Ohmmeter legen eine Reizspannung von 3-10 V an das zu testende Gerät (DUT) an. Diese Reizspannung kann das zu untersuchende Gerät zerstören!
Der ΩhmRanger-LCV™ wird zur sicheren Aufbewahrung in einer robusten, schützenden Tragetasche geliefert.
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."
