GODIYMODULES Precision Voltage Reference Module User Manual

Introduction

The GODIYMODULES Precision Voltage Reference Module is designed for accurate voltage and resistance calibration. It features low-temperature drift components and is powered via a Type-C 5V port, eliminating the need for a battery. This module provides five distinct voltage reference levels and five resistance reference levels, making it suitable for verifying the accuracy and linearity of digital multimeters.

Figure 1 : De haut en bas 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.

Installation et connexion

1. Alimentation: 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.
2. Connexion de sortie : Use appropriate test leads to connect your multimeter or device under test to the red (+) and black (-) output terminals on the module.
3. Environnement: 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.

Mode d'emploi

Sélection du volumetage Référence

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 voltage niveau.

• Commutateur 1 : 1.24V
• Commutateur 2 : 2.5V
• Commutateur 3 : 5V
• Commutateur 4 : 7.5V
• Commutateur 5 : 10V

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.

Usage for Multimeter Calibration

• 3 1/2 Digit Multimeters: The module can be used to verify the accuracy and linearity of handheld 3 1/2 digit digital multimeters.
• 4 1/2 Digit Multimeters: For 4 1/2 digit digital multimeters, it is crucial to maintain the same temperature and humidity conditions as specified in the multimeter's data sheet for accurate verification.

Entretien

• Nettoyage: Veillez à ce que le module reste propre et exempt de poussière et de débris. Utilisez un chiffon doux et sec pour le nettoyer.
• Stockage: Store the module in a dry environment, away from extreme temperatures and humidity.
• Manutention: Manipulez le module avec précaution afin d'éviter tout dommage physique aux composants ou aux connexions.

Dépannage

• Aucun indicateur d'alimentation (LED verte éteinte) :
  • Ensure the Type-C power cable is securely connected.
  • Verify that the 5V Type-C power source is functional and provides at least 0.5A.
• Vol incorrecttage Sortie :
  • Check that only one voltage selection DIP switch is in the "ON" position.
  • Ensure proper connection to the multimeter.
  • Verify environmental conditions (temperature, humidity) for sensitive measurements.
• Lectures instables :
  • Operate in a low airflow environment to prevent temperature fluctuations.
  • Avoid direct cold wind from air conditioners.
