: Some data will not be updated. If this occurs, previous data is displayed consecutively.
If you set the sample rate (the main channel sample rate setting) of the DL850E/DL850VE to a rate
that exceeds the sub channel data update rate, all data within the sub channel data update interval
will be the same.
