Error upon connection check
QThe instrument indicates an error when it checks the connection, even though it is connected properly.
AThe connection check function may indicate an error even though the instrument is connected properly, or it may yield an OK result even though the instrument is not connected properly. Check for problems with the vector display or measured values. Particularly when the power factor is 0.5 or less, the phase difference (I-U) may trigger an error even if the instrument is connected properly. If you check the connection and find no problem, measurement can be performed without issue despite the indicated error.
