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 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
 
 

 
Functions:
              

- Voltmeter mode - the device simply reflects current voltage values. The controlling circuit is closed.
- Voltmeter mode with sag and swell indication - the device displays and checks the value of
  measured voltage for correspondence with the range set in configuration. 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 becomes even lower (primary overswing on the range lower limit) or higher 
  (primary overswing on the range upper limit). The controlling circuit is closed. LED and display start to blink until the Reset button is pressed.

- Voltmeter mode with sag and swell indication and feature of breaking the controlling circuit - the
  device displays and checks the value of measured voltage for correspondence with the range 
  set in configuration. If the voltage oversteps the defined range, the device comes into the
  peak hold mode changing the value on-screen only in case if value becomes even lower 
  (primary overswing on the range lower limit) or higher (primary overswing on the range upper limit). 
  The controlling circuit is broken, LED and display start to blink until the Reset button is pressed.
