The DCR100 will not allow me to switch on/off a relay channel. Why?

The DCR100 has a DC current calibration option. If you have connected a DC load to a channel of the DCR100 and have not performed the "Current Sensor Zero Offset Calibration", this may affect the command of this channel especially if the DCR100 detects a negative DC current value to the load.

You can perform the DCR100 "Current Sensor Zero Offset Calibration" within the Advanced Configuration menu of the DCR100, as shown int eh following image:

The following image shows how to perform the "Current Sensor Zero Offset Configuration" using the DSM150 or DSM250.
