Performance and Features
The digital voltmeter monitors your battery and alternator voltage in real-time. If the reading drops below normal levels, you’ll know to take action before a failure occurs. The indoor thermometer uses the unit’s built-in sensor, while the external probe with its 200 cm cable can be discreetly routed through a door or window seal. The digital clock supports both 12H and 24H formats and automatically cycles through the three displays at regular intervals.

Frequently Asked Questions
Does it work on both 12V cars and 24V trucks without adapters?
Yes. The device natively supports voltages between 12V and 24V, making it suitable for cars, trucks, caravans, and tractors without any modifications.
Is the external probe resistant to frost and moisture?
The probe is rated for temperatures down to -50°C and is weather-resistant. While it should not be submerged directly in water, it is perfectly suited for standard exterior use, including during severe winter weather.
Will I lose the time settings if I disconnect the vehicle?
This depends on your installation. If connected to a permanent power source (e.g., directly to the battery via a fuse), the time will be retained. If connected to a switched cigarette lighter socket, settings may reset when the engine is turned off.
Is the LED display visible in daylight?
Yes, the display offers sufficient contrast for clear reading in normal daylight conditions. The backlight activates automatically when the vehicle’s lights are turned on at night.
