Electronic Meter (Optical Port On Face-Shims Required); Preparing Your Sensor Unit - Blue Line Innovations PowerCost Monitor User Manual

5.4. Electronic Meter
Electronic meters have digital readouts, as well as an optical port which emits light pulses similar
to the infrared light produced by a television remote control.
This section deals with electronic meters that have their optical port on the face, at a distance
LESS THAN 1.5 inches (37 mm) from the outer rim of the meter dome. If in doubt, physically
measure the distance between your port and the outer rim of the dome. If it is equal to or more
than 1.5 inches (37 mm), follow the instructions in section 5.3 to install your Sensor Unit.
Here are two examples of such meters.Although the meter in the photo on the right hand side
appears to have two optical ports, it has only one, and it is the opening located closest to the
meter's center.

5.4.1. Preparing Your Sensor Unit

Proceed as follows:
1. Pull the Sensor Arm latch upward to open it.
2. Ensure that the Sensor Arm is completely pushed
in as far as it will go.
3. Close the latch.
In these electronic meters, the optical port is too close to the dome's outer rim for it to be
possible to position the Sensor Head over the port, because the Sensor Arm is too long,
even when fully pushed in.
