    in reply to: description explanation #7471

    Hello,
    You’re welcome.
    When you calibrate the current/voltage, it is recommended that the measured value is half of the measuring range, which can reduce error.
    The measured value is the value of the load (device) which need to be measured, but not the value of the power supply for the meter.
    Hope this can help you.
    Best regards
