Description: 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 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 car electronics operation process, protection of electrical equipment of a car from breakage, possibility of flexible setting and easy use. The voltmeter can easily change data refresh speed onscreen (from once a second to once per quarter second), which allows excluding the unnecessary details or to make measurements with maximum possible accuracy. The device has three working modes that are 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 3with 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, protecting 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, thus in case of necessity replacing an additional relay.Smart Monitor form SplLab will protect your car audio components from breakage, will help in tuning sound in the car, as well as will measure power of your sound system and acoustics characteristics. Actually the Smart Monitor replaces amp clamp, True RMS digital voltmeter, and oscilloscope, and in addition to this provides protecting functions.
Ergonomics: 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.
Device work modes: The Smart Voltmeter has three work modes. Working mode is changed by pressing the Functional button #1. For indicating current working mode there is a three-coloured LED. Detailed description of working modes: - Voltmeter (green LED) - the device displays present measured voltage value. The Remote controlling circuit is closed if the signal on contact #4 (Remote In) of the slot is present. - Voltmeter mode with sag and swell indication (yellow LED) - the device displays and checks the value of measured voltage for correspondence with the range set in configuration menu. If the voltage oversteps the defined range, the device comes into the pick hold mode changing the value on-screen only in case if value overstepped the permissible range even more, in so doing the LED and display start blinking until reset button is pressed. The Remote controlling circuit is closed if the signal on contact #4 (Remote In) of the slot is present. - Voltmeter mode with sag and swell indication and feature of breaking the controlling circuit (red LED) - the device displays and checks the value of measured voltage for correspondence with the range set in configuration menu. If the voltage oversteps the defined range, the device comes into the pick hold mode changing the value on-screen only in case if value overstepped the permissible range even more, in so doing the Remote controlling circuit is broken, the LED, and display start blinking until reset button is pressed. The Remote controlling circuit is closed if the signal on contact #4 (Remote In) of the slot is present.
