Dvb01 User Manual Hot! -

Use either HDMI (for modern TVs) or the composite AV lead via the 3.5mm jack (for older TVs). Both outputs can be used simultaneously.

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.

All parameters are automatically saved and retained after power failure. Operational Modes (5 Preset Functions)

The module uses two tactile pushbuttons labeled and SW (Switch) to navigate the onboard menu and adjust variables. Step 1: Selecting the Function Mode (F1 - F5)

If you want to minimize the module’s own energy consumption (e.g., in a standalone solar or battery setup): dvb01 user manual

Proactively optimize your setup by reviewing your specific wiring needs. If you would like to proceed with configuring your module, let me know: What is the of your module's power source?

Use + and - to adjust the display to match the true voltage. Press SET to save. 7. Troubleshooting

Automatically saves settings, even during power-off. 2. Wiring and Installation Instructions

: Voltage detection input port. Connect this terminal to the positive terminal of the target voltage source you wish to measure and monitor (0–99.9V DC). Use either HDMI (for modern TVs) or the

: Verify your external load draw. If your load requires more than 10 Amps, the internal contact point may have fused. You must route the DVB01 output terminal to trigger an external high-power AC/DC contactor or heavy-duty automotive relay rather than driving the high-current load directly.

Relay activates when the voltage is below the low limit (P₂) and turns off when it exceeds the high limit (P₁).

| Mode | Relay Action | Typical Use Case | | :--- | :--- | :--- | | | Relay never activates. Only measures and displays voltage. | A simple, high-precision voltmeter. | | F-02: Charge Monitor (Hysteresis) | Turns ON when voltage drops below the lower limit. Turns OFF when voltage rises above the upper limit. | Prevents a battery charger from continuously cycling on and off once a battery is full. | | F-03: Discharge Monitor | Turns ON when voltage is above the upper limit. Turns OFF when voltage drops below the lower limit. | Protects a load (like an inverter) from over-discharging a battery. | | F-04: Within Range | Turns ON when voltage is between the V1 and V2 limits. Turns OFF otherwise. | Ensuring a device only operates when voltage is within a safe operating "window". | | F-05: Out of Range | Turns ON when voltage is outside the V1 and V2 limits (either below the lower or above the upper). Turns OFF otherwise. | Activating an alarm or protection circuit when voltage goes outside a safe range. |

To prevent short circuits, turn off the ignition and disconnect the negative (-) battery cable prior to installation. If the vehicle has an on-board computer, do not disconnect the battery cable (as this may erase computer memory). When dealing with high voltage, ensure all wires

– 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%.

Press the or NUM buttons to cycle through the functions ( F-1 , F-2 , F-3 , F-4 , F-5 ).

The display will show P- 0 .
