Power Source Connection
Before connecting your meter to the power source, check the label on the
back of the device to ensure that it is equipped with the appropriate power
supply.
The power source can be dedicated-fused, or from a monitored voltage if it is
within the instrument power supply range.
AC power supply: connect the line wire to terminal 12 and the neutral wire to
terminal 10.
DC power supply: connect the positive wire to terminal 12 and the negative
wire to terminal 10.
