OPTION2

This packet contains information on the operation mode of the meter. The format is shown below. The
DC field indicates that the meter operates in DC measurement mode, either voltage or current. The AC
field indicates that the meter operates in AC measurement mode. The AUTO field is set to one if the
meter operates in automatic mode, and in set to zero when the meter operates in manual mode. The
APO field indicates whether auto power off function is enabled or not.

CR

Carrage return. The transmitted cord is 0001101.

LF

Line feed. The transmitted cord is 0001010.
