adjustment screw until the Sensor Unit cannot be moved easily. Do not
over-tighten!
8. Press and release the RESET button on the battery cover of the Sensor
Unit, as shown in figure 5.7. The red indicator on the Sensor Unit will
begin to flash once per second. It will take approximately 15-30 seconds
for the Sensor Unit to determine that it is installed on an
electromechanical meter. Once it has determined this, the red indicator
light will begin to flash every time the black mark on the disk passes in
front of the Sensor Arm.
If, after a few minutes, the Sensor Unit indicator does not flash when the
black mark passes, or if it flashes while the black mark is not visible,
then the Sensor Arm is not properly aligned and must be re-adjusted. To
adjust the Sensor Arm, open the Sensor Arm latch and gently move the
Sensor Arm up or down a few millimeters to align it with the meter disk.
Close the Sensor Arm latch then repeat this step. Continue to do this
