Customer Questions & Answers
What are the materials and exact dimensions of the device and the display size of the LED screen?
The housing is made of black plastic, with approximate dimensions of 23 mm x 12 mm for the display and a cable length of 190 mm. The module is usually easy to panel-mount thanks to its compact size. It does not include a sealed housing or metal reinforcement materials.
How does the device respond to reverse polarity connection and what is its typical current consumption?
The voltmeter includes reverse polarity protection, preventing damage if the wires are connected the wrong way round. Typical consumption is 15 mA, with a maximum of 60 mA under normal operating conditions. This allows it to be installed in battery-powered systems without significantly affecting runtime.
What is the measurement accuracy tolerance and what margin of error can be expected under standard conditions?
Measurement accuracy is ±1% within the specified operating range. For example, when measuring 12.0 V, the margin of error may be ±0.12 V. Factors such as extreme temperature or interference could slightly affect accuracy, but the stated margin is maintained in most common scenarios.
What voltage range does this mini digital voltmeter measure?
This mini voltmeter measures voltages from 3.5 V to 30 V DC with an accuracy of ±1%.
Does it need batteries to work?
No, the mini voltmeter is powered directly by the voltage it is measuring, so it does not require a battery.
Does it have reverse connection protection?
Yes, it includes reverse polarity protection to prevent damage if connected incorrectly.
What applications is this voltmeter suitable for?
It is ideal for measuring the voltage of vehicle batteries, solar systems, and other electrical equipment within the specified range.
How is the mini digital voltmeter installed?
It can be easily panel mounted in panels or enclosures thanks to its compact design and 190 mm cables for connection.
