RR-DS Meter Disk Sensor
The RR-DS is a reflective pickup assembly used to sense the disk rotation of an induction type me-
ter. The pulses generated by the RM-DS are fed into the PICKUP port of the RD-30. Evaluation of
different types of meter designs is fully automated when the Built-in Computer option is utilized.
The RR-DS is available in two (2) different mounting options. The RR-DS/f Disk Sensor with Field
Mount features a Velcro strap that attaches around the meter cover. This allows the sensor to sense
disk rotation from the side of the meter. The RR-DS/sm Disk Sensor with Suction Mount features
an L-bracket with three (3) suction cups that attach to the front of the meter cover. This allows the
sensor to sense disk rotation from the front of the meter.
RR-1H Optical Pickup for Infrared LED
The RR-1H 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 PICKUP port of the RD-30. Evaluation of different types of
meter designs is fully automated when the Built-in Computer option is utilized. The wide angular
displacement of this sensor allows for fast, non-critical alignment. Also, automatic gain control cir-
cuitry of the RR-1H assures operation in all ambient sunlight conditions. The RR-1H/v is available
for those solid-state meters with a visible calibration LED, and terminates in a BNC Connector instead
of a lemo connector. Therefore, the RR-1H/v attaches to port 1 instead of the pickup terminal.
