Optical Pickup
The Optical Pickup is used with solid-state meters. It is mounted with a suction cup
or integrated in a magnetic head that detects infrared light pulses from solid-state
meters. The Optical Pickup uses edge triggering for less sensitivity to changes. On
the top of the head of the pickup, there is a pulse indicator in the form of a visible
red led that flashes when pulses are being received.
