Spl-Lab Smart Voltmeter - is multifunctional digital car voltmeter. Although most of car electronics manufacturers state that their products have inbuilt protection from supply voltage sags or swells, in actual practice it turns out that not every, even expensive, amplifier is able to cope with this task. It means that another voltage overrun can end with expensive repairs or buying new unit. But if you add to your system an inexpensive device from Spl-Lab you can forget about such problems once and for all. Main functions of the Smart Voltmeter are the following: measuring exact characteristics of a car electric network voltage, analysing voltage sags and swells that appear in the operation process of car electronics, protection of electrical equipment of a car from breakage, possibility of flexible settings and easy use. The voltmeter can easily change data refresh speed on-screen (from once a second to once per quarter second), which allows excluding the unnecessary details or to making measurements with maximum possible accuracy. The device has three working modes that can be changed with just one button: voltmeter mode; voltmeter mode with sag and swell indication; voltmeter mode with sag and swell indication and protection feature. For indicating current mode there is a three-coloured LED. User can easily set permissible voltage range for setting the electrical equipment. In the sag and swell indication mode the car voltmeter displays current voltage and in case if the permitted range is overstepped, the voltmeter will inform the user about it by holding maximum or minimum value onscreen for evaluating the degree of sag or swell. In the protection mode in case if the permitted range is overstepped, the voltmeter will break the remote controlling circuit before user’s interference, and protect electrical equipment from breakage in doing so. It stands to mention that Smart Voltmeter is able to commutate the Remote controlling circuit with current up to 3 ampere, and by that to replace an additional relay in case of necessity
Spl-Lab car voltmeter has compact case, including a three segment display, 4 control buttons, three coloured LED for indicating active working mode and slot for five contacts that has several variants of connection to the electric system of a car. The design of the device allows including it practically in any car interior.
