Расми 1: Аз боло ба поён view of the GODIYMODULES Precision Voltage Reference Module. This image shows the overall layout of the module, including the Type-C power input, DIP switches for selecting voltage, and output terminals.
The module incorporates an EMI filter for a cleaner power supply. It includes a green LED to indicate power status. The compact design (85x55x25mm) makes it convenient for various applications.
Танзим ва пайвастшавӣ
- Таъмини нерӯ: Connect a 5V Type-C power source (0.5A minimum) to the Type-C port on the module. The green LED will illuminate to indicate power.
- Пайвасти баромад: Use appropriate test leads to connect your multimeter or device under test to the red (+) and black (-) output terminals on the module.
- Муҳити зист: For optimal accuracy, especially when verifying 4 1/2 digit multimeters, ensure the working environment maintains a stable temperature (16-30℃) and humidity (RH≤70%). Avoid direct airflow from air conditioners, which can introduce errors.

Интихоби ҷилдtage Маълумотнома
The module provides five voltage reference levels: 1.24V, 2.5V, 5V, 7.5V, and 10V. These are selected using the DIP switches labeled 1 to 5. Each switch corresponds to a specific voltagсатҳи e.
- Гузариш 1: 1.24В
- Гузариш 2: 2.5В
- Гузариш 3: 5V
- Гузариш 4: 7.5В
- Гузариш 5: 10В
Caution: Only one DIP switch for voltage selection should be in the "ON" position at any given time. Activating multiple voltage switches simultaneously is not permitted and may lead to incorrect readings or module damage.
Selecting Resistance Reference
The module provides five fixed resistance reference levels: 10Ω, 100Ω, 1KΩ, 10KΩ, and 100KΩ. These are available at dedicated terminals on the board. To measure a specific resistance, connect your multimeter to the corresponding resistance terminals.
