    FAQ

    Q1: How do I calibrate linear DC power supply?

    To calibrate this linear adjustable DC power supply, first ensure it is off and connect a calibrated voltmeter to the output terminals. Set a target voltage, turn on the unit, and adjust the output knob until the voltmeter matches your desired value. Repeat this process across multiple voltage points to check for discrepancies. You can also calibrate the current limiting function with a calibrated ammeter and load resistor, then document all results and schedule periodic recalibration to maintain performance.

    Q2: What should I do if the linear DC power supply fails to output the set voltage?

    First, check if the unit is in constant current (CC) mode, as this will limit voltage output when the load draws more current than the set limit. Verify your load requirements and adjust the current limit accordingly, then confirm all connections are secure and free from short circuits. If issues persist, review the calibration records or perform a fresh calibration to ensure accuracy.
