Radian RM-111 Operation Manual page 91

The RR-1H Infrared Optical Pickup is used to sense the infrared pulses from the calibration
LED of solid state meters. The pulses from the RR-1H are fed into the input of the RM-111 into the
Pickup port. When the RR-1H is used with the RM-111 Automated Comparator the testing of solid
state meters is done automatically. The wide angular displacement of this sensor allows for fast,
non-critical alignment. Also, automatic gain control circuitry of the RR-1H assures operation in all
ambient sunlight conditions. The RR-1H/v is also available for those solid state meters that have a
visible calibration LED.
The RM-OA Optical Adapter is used with solid state meters whose infrared calibration pulses
are emitted from the optical communications port. The RM-OA magnetically couples to the
communications port of solid state meters. The suction cup of the RM-1H is attached to the clear
polycarbonate cover of the RM-OA. The RM-OA incorporates a rare earth permanent magnet for
exceptional holding power over the life of the product.
