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 generated by solid-
state meters. The optical pickup uses edge triggering for less sensitivity to changes.
On the top of the pickup’s head, there is a pulse indicator in the form of a visible red
LED that flashes when pulses are being received.

Optical Pickup for meters with a
protuberant shape over the test pulse.
The Magnetic Adapter is used to affix
the Optional Pickup’s suction cup on
meters with a metallic port.
