The DVB01 is an affordable, versatile tool. When dealing with high voltage, ensure all wires are secured, as mentioned in similar DVB Combo Meter manuals . Always double-check your voltage limits before connecting your final load.

): Continuously monitors and displays the current DC voltage. Charge Monitoring (

– Power cycle the device. If the issue persists, check the input voltage is within the specified operating range (5V/12V/24V) and does not exceed nominal voltage by more than 10%.

is a multifunctional voltage monitoring controller used to trigger an onboard relay based on specific DC voltage thresholds. It supports a measurement range of 0V to 100V DC with an accuracy of approximately Amazon.com 1. Interface & Connections

Important: When entering parameter setting mode, all functions stop running and return to their original state. Upon exiting, the module starts running the selected functions.

Disconnected from COM when the relay is off; connects to COM when the relay triggers (turns on). Use this for most applications where you want to power a device only when conditions are met.

Function 5 (F-5): External Interval Pull-In (Outside Window Comparator)

Typically less than 90mA at 5V; drops to less than 3mA when the display is closed to save power.

The DVB01 manual typically opens with a standard “Safety and Package Contents” section. According to most versions:

This manual will help you quickly identify which device you have and provide the specific instructions you need.

Connect the operating power supply for the board.

The is a multifunctional digital voltage monitoring controller used for precision voltage measurement and circuit control. It is widely used in charge/discharge monitoring, overvoltage/undervoltage protection, and automated voltage relay switching. Key Technical Specifications

Function 4 (F-4): Interval Pull-In (Inside Window Comparator)

Actuates the relay based on a single set point P1 with a "window" P2 for hysteresis to prevent rapid switching. 6. Troubleshooting & FAQs
