Page 5: Product Introduction
120 amps or 200 amps per phase. The auxiliary power ranges from 60 to 630 volts. In the field, the RD-30 can be used with a controlled current load, or it can be used with clamp-on current transformers available from Radian Research to perform customer load tests. In this field application, the optional power analysis capability can analyze customer load through the 204 harmonic order. -
Page 6: Enhanced Design Features
The RD-30 also provides a serial communications port which allows direct connection to the RS- 232 serial port of a personal computer. RD-30s with the Built-in Computer option come with RR- MobileSuite software. The RD-30 is available in a variety of models offering measurement functions and options to suit specific needs. 1.1 Enhanced Design Features Many design features have been added or improved through the engineering process of designing the RD-30 Dytronic. - Page 7 Product Introduction In addition, the RD-30 can analyze harmonic distortion complete with each order’s phase and amplitude. This information can be studied in the laboratory with Radian software for a more complete understanding of conditions at specific meter installations. Additionally, voltage and current waveforms can be viewed in real-time and then captured for later investigation.

The other accepts a voltage signal and is linked with two voltage references. These of course are for the analog voltage and current inputs of the RD-30. Both operate independently to provide the digital signal processor with signals accurate enough to meet the requirements of a true portable electricity standard. -
Page 18: Auxiliary Power Inputs
4.5 Auxiliary Power Inputs Auxiliary power is required to power the internal workings of the RD-30. It may be derived from the same signal as the potential input providing that there are sufficient volt-amperes available. Auxiliary power may also be supplied independent from the potential input source. The power supply for the RD-30 is a very advanced switching power supply which is inherently capable of converting the available input power to regulated power over the entire operating range. -

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. - Page 64 The RR-KYZ Pulse Input Adapter is used to sense the KYZ output pulses of induction or solid-state meters. The Pulses received from the meter’s KYZ output are conditioned and fed into the PICKUP port on the RD-30. The testing of KYZ equipped meters is done automatically with the Built-in Computer option of the RD-30.
- Page 65 The RM-1S Remote Reset Switch is a normally closed push button switch. The RM-1S connects directly to Port 1 of the RD-30. The switch of the RM-1S is hermetically sealed. The push-button has positive tactile feel to provide instantaneous feedback of the switch action.

Page 66: Appendix: Rd Current Connector Locking Mechanism
Note: These connectors are very specialized and feature beveled edges and a locking ring. Do NOT use straight ¼” current connector studs. Radian offers various jumpers and adaptors to fit most applications. When connecting to the current inputs, insert the 6mm current plugs slowly into the current input receptacles on the RD standard. - Page 67 To disengage the locking plug, firmly insert the current input plug further into the receptacle until you feel a slight click. This click indicates that the locking mechanism is disengaged. You can then pull the current plug completely out of the receptacle.
