Page 3: Functions And Technical Features Of The Device
Functions and technical features of the device 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. -
Page 4: Ergonomics
with 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. -

Page 8: Typical Device Connection Schemes
Typical device connection schemes Simple voltmeter Such scheme implies that the device works as a simple voltmeter. The two-contact connection provides device power supply directly from the measured line. Measures voltage range in this case is limited from 6 to 18 volts. Contact Description Should be connected to the negative contact of the car electric network. -
Page 9: Contact
Contact Description Negative (common), should be connected to the negative contact of the car electric network. + 12 V for feeding the device, it is possible to connect to any supply line, for example to the ignition or to the Remote. Output signal of the Remote controlling circuit should be connected to the amplifier or other controllable equipment. -
Page 10: Device Work Modes
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.
