DVB01 Digital Window Voltage Comparator: User Manual & Setup Guide
The relay remains inactive. The screen simply acts as a digital voltmeter.
The relay closes when the voltage drops below the lower limit (V1) and opens when it hits the upper limit (V2). Perfect for battery chargers. dvb01 user manual

If the relay clicks rapidly on and off, your V1 and V2 values are likely too close together. Increase the "hysteresis" (the gap between the two numbers) to stabilize the switching.
Use the SWI button to move the cursor and the NUM+ or NUM- buttons to change the digit. Perfect for battery chargers
