Installing the MOSAIC Electric FIREFLY
Note: All work on Electric FIREFLYs needs to be done taking static grounding precautions. Failure to use a
grounded static mat and wrist strap when handling or retrofitting the FIREFLY to an electric meter could result in
static discharge damage to the electronics. Units found to be damaged in this manner will not be covered by
Datamatic warranty. See picture of static mat below:
1. Remove the break-away brass tamper seal, if equipped. Remove the glass cover from the electric meter.
2. Remove the screws from the utility faceplate.
3. Remove the utility faceplate from the meter. Clean the disc on old meters, if necessary.
4. Place marking template over meter disc, being sure to include one calibration hole and any black painted
stripe in the marking area, as illustrated below:
Note: When painting the disc, make sure calibration holes that do not fall within the painted area will not be
positioned over the FIREFLY optics at the same time as the painted area.
5. Using the Datamatic D2311 paint marker, paint in the entire area of the template. Leave no empty
spots within the template area.
