SPL-Lab SMART Voltmeter

This is not a typical voltmeter that can be found on the internet.

This voltmeter is the following-

Voltmeter
3A relay circuit (no 5pin wiring)
Min/Max Voltage Protector

Now, let's look at the features and description-

This device is a 5 wire voltmeter
Power
Ground
Measuring wire
Remote IN
Remote OUT

This tiny voltmeter has a built in 3A relay circuit already wired internally.

This means the user no longer has a need to add a relay to their remote wire when adding multiple amplifiers, etc..

Now, let's look at the voltmeter-
Depending on the mode selected in the menu, the Voltmeter will display 3 different color modes on the front LED indicating which mode it is working in-

Green = Voltmeter only
Yellow = Voltmeter with visual warnings
Red = Voltmeter with active voltage protection

Setting refresh speed on SMART Voltmeter-
This can be set to 1x, 2x or 4x per second.

The speed of refresh IS the speed of measure!

Protection-
Defaulted to the following-
10.8v LOW - 15.5v HIGH

User can adjust the minimum and maximum thresholds within 0.1v increments as required per install.
