The fiber optic transmitter / receiver system
contains two (2) diagnostic LEDs that are located
in the receiver. These indicators make it easy to
verify proper operation.
To verify proper operation perform the following
steps:
1. Cause fluid to flow in the meter in the forward
direction at a flow rate greater than 10cc/min.
2. Observe the diagnostic LEDs located on the
receiver PCB. The green “forward” LED should be
flashing. One flash is generated each time a gear
tooth passes the pickup tip.

3. The flashing green led verifies the transmitter,
fiber cabling, and about 75% of the receiver
circuitry.
4. The system should be functioning normally
at this point. If it is, replace the cover on the re-
ceiver. If not, proceed to the following trouble-
shooting section.
