රූපය 1: ඉහළ සිට පහළට 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.

සැකසුම සහ සම්බන්ධතාවය

1. බල සැපයුම: 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. ප්රතිදාන සම්බන්ධතාවය: Use appropriate test leads to connect your multimeter or device under test to the red (+) and black (-) output terminals on the module.
3. පරිසරය: 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.

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 voltagඊ මට්ටම.

• 1 මාරු කරන්න: 1.24V
• 2 මාරු කරන්න: 2.5V
• 3 මාරු කරන්න: 5V
• 4 මාරු කරන්න: 7.5V
• 5 මාරු කරන්න: 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.
