Calibration of ZK-DPL DC-DC USB/Micro USB Buck Boost Power Supply Voltage Regulator Module

The ZK-DPL module allows for the calibration of both output voltage and current for accurate readings. Below are the steps for calibration:

Calibrate Output Voltage Accuracy:

1. Enter Voltage Calibration Mode: Long press the "SW" button while displaying the output voltage until the screen starts flashing.

2. Adjust Voltage:

   • Short press the "ON" button to decrease the value.

   • Short press the "SW" button to increase the value.

3. Save Settings: Long press the "SW" button again to save and exit calibration mode.

Calibrate Output Current Accuracy:

1. Enter Current Calibration Mode: Long press the "SW" button while displaying the output current until the screen starts flashing.

2. Adjust Current:

   • Short press the "ON" button to decrease the value.

   • Short press the "SW" button to increase the value.

3. Save Settings: Long press the "SW" button again to save and exit calibration mode.

Note: The higher the current, the more accurate the calibration. The module cannot display current if the output is less than 10-30mA.
