AcuDC 210/220 Series
As shown in Fig 2.20, an anti signal reflecting resistor (typical value 120~300 ohm
/0.25W) is added to the end of the circuit beside the last AcuDC 210/220 meter if
the communication quality is distorted.
2. Circle
AcuDC 210/220 meters are connected in a closed circle for the purpose of high
reliability. No anti signal reflecting resistor is needed for circle mode.
