The address switch has a hexadecimal setting position (0..F). Most datalogger
instructions require you to enter the address as a base 4 number. Please see your
datalogger manual for more details of the convention required.

4.5 Safety Considerations

Where the potential voltage difference between the datalogger and the
SDM-CVO4 outputs is considered to be non-hazardous (less than 50 V) then the
unit can be used as any other peripheral without undue concerns as to the risks to
safety of the user.

As with the datalogger, it is essential to ensure that the device has a good
connection to an earth grounding point to allow the safe discharge of any transient
voltages and also ensure proper screening of the device. The
SDM-CVO4 has two G terminals on the black connector which are used for
connections to the datalogger. One of these can be used to connect the device
directly to the earth ground point of the enclosure to ensure the lowest resistance
path to ground.
