while providing a high level of accuracy through design innovations. The RD-33 has a
guaranteed accuracy of 0.01%. This specification includes variables of stability, temperature,
power factor, traceability uncertainty, and test system errors. In addition, this accuracy applies
across the entire voltage and current operating range of the product for one year.
The RD-33 utilizes Radian’s new Dytronic measurement technology consisting of a Radian
designed Integrating Analog to Digital Signal Converter. The RD-33’s Dytronic A/D Converter
is combined with Radian’s renowned electronically compensated voltage and current input
transformers and a hermetically sealed reference set to provide the highest degree of accuracy,
stability and versatility offered in a portable three-phase electricity standard.
The RD-33 provides four quadrant three-phase simultaneous measurements for active, reactive,
and apparent energy and power with forward and reverse energy flow also measured. The
potential input, current input and auxiliary power input are totally autoranging. This autoranging
feature was pioneered by Radian Research and makes it impossible to damage the unit by
applying a signal to the wrong tap. The potential input range is 30 to 630 volts, the current input
range is available as either 120 amps or 200 amps per phase. The auxiliary power ranges from 60
to 630 volts.
In the field, the RD-33 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 200th
harmonic order. In addition, for improved efficiency, the RD-33 optionally can automatically
calculate and display the error of the meter under test.
The RD-33 also provides a serial communications port which allows direct connection to the RS232 serial port of a personal computer. RD-33s with the Built-in Computer option come with RRMobileSuite software.

Many design features have been added or improved through the engineering process of designing
the RD-33 Dytronic. The addition of A/D and DSP technology, increased PC support and an
enhanced version of Radian’s revolutionary voltage and current transformer input design make
the RD-33 the benchmark of portable standards. The RD-33 utilizes Radian Research designed
Analog/Digital circuitry coupled with Digital Signal Processing techniques. These advancements
provide a high degree of flexibility including simultaneous multifunction measurements and
harmonics analysis capabilities.
A/D and DSP Technology
In order to accelerate the testing process, Radian Research has designed and incorporated a
custom integrating Analog to Digital Converter into the RD-33. There are separate A/D circuits
for both the voltage and current axes. Couple this enhancement with the utilization of DSP
technology and the RD-33’s abilities are greatly enhanced. The RD-33 can effortlessly collect
the converted digital signals from the A/D converters and process the data to display every
measurement function supported during a single collection of voltage and current data.

A/D Converter is specifically designed and optimized for power and energy measurement. This
unique design allows the RD-33 to accurately measure non-sinusoidal waveforms up to and
including the 200th harmonic order. Measurement parameters include the phase and amplitude of
each harmonic as well as the total harmonic distortion. The unprecedented accuracy of measuring
distorted waveforms combines with this optional power analysis capability to clearly distinguish
the RD-33 as the definitive portable three-phase electricity standard for both meter testing and
power quality applications. This power analysis option is also useful when testing meters using
customer load.

RD-33 Operations Manual
Operations Overview

4.1
Operations Overview
Measurement Principle
The RD-33 measurement principle is based upon the fundamentals of a high-speed charge-balance
integrating analog to digital signal converter. This is a Radian innovation, but it is based upon
accepted metrology parameters. Radian Research implemented its own analog to digital converter
in the Dytronic family of standards which are specifically designed for power measurement. In order
to measure power and energy with extreme accuracy and wide bandwidth, extensive requirements
must be imposed on the converter.
The RD-33 Dytronic utilizes two separate A/D converters. One accepts a current signal and is
linked with two current references. 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-33. Both
operate independently to provide the digital signal processor with signals accurate enough to meet
the requirements of a true portable electricity standard.
By designing an analog to digital converter specifically for power and energy measurements,
Radian is able to reduce many errors associated with commercial A/D circuits. Gain error,
charge timer resolution, signal to noise ratio and signal distortion were major areas dealt with and
improved in development.
4.2
Internal Reference Set
The RD-33’s internal reference set is hermetically sealed in order to protect it from environmental
variables. The internal reference set consists of a voltage reference, a resistive reference and a crystal
time reference.
4.3
Display and Pulse Output
The RD-33 displays the measurements and provides pulse outputs for the selected measurements.
Computer control, with Radian software, allows for customization of output information, such as
programmable pulse output constants.
17
RD-33 Operations Manual
Operations Overview
4.4
Voltage and Current Inputs
The voltage and current inputs are completely autoranging – a design feature that was pioneered
by Radian Research with the RM-10 in 1985. The voltage and current inputs consist of a toroidal
autoranging electronically compensated transformer which reduces the need for switching relays
that can prove unreliable over time. The specially designed and manufactured Radian toroid
transformer provides superior immunity to stray fields while electronic compensation eliminates
practically all of the transformer error.
4.5
Auxiliary Power Inputs
Auxiliary power is required to power the RD-33’s measurement circuits. Power 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-33 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 converter is so effective at this that the input may be changed freely between the ranges of 60
and 630 VAC during operation without a measurable effect upon operation.
The connections have been updated to an insulated socket design. The Potential Input and Auxiliary Power Input are 4mm connections and the Current Inputs are 6mm connections (bolt-on
design for 200 amp models).*

3 (Phase C input) and can be used to gate (start/stop/reset) all three inputs simultaneously. Alternatively, any of the available Radian pickups may be connected to input 3 (Phase C input). The
pickups consist of the RM-1H, RM-DS, and RM-KYZ, all which can be used to test various
electricity meters. While performing a standards test all three inputs can be used individually or
simultaneously.

4.12 Chassis Ground, Guard, Neutral
Chassis Ground – ideally tied to the best available earth ground. If the RD-33 is mounted in a
rack, no connection is required. The Chassis grounds main purpose is for safety.
Guard – should be tied to the common of the Wye source for Wye usage and left to float in Delta
use applications. Because the Analog Sense is common with the Guard ground, care must be
taken to avoid ground loop problems.
V1, 2, 3 / VN – the three VN connections should be tied together, via twisted wire pair, with their associated Potential Inputs (V1, V2, V3). At the Device Under Test (DUT), each VN should be broken
out from its associated twisted wire pair and each tied to the DUT Neutral with the three Potentials
(V1, V2, V3) tied to the three Potential connections of the DUT. The three Potentials (V1, V2, V3) of
the DUT should be tied to the associated three Potentials of the source. If using a Wye source, the
Neutral from the DUT, containing the three VNs, should be tied to the Wye source neutral. If using
a Delta source, the DUT Neutral, containing the three VNs, should be allowed to float.

Service & Routine Maintenance
5.0
Service & Routine Maintenance
The RD-33 Dytronic portable electricity Standard is virtually maintenance free. The elimination
of all contacts, switches and tap selections on the primary side of the input transformers
significantly improves reliability by eliminating both service components and the opportunity for
operator error. Other than cleaning of the outside surface and the yearly recalibration, no routine
maintenance is required.
5.1
Cleaning
Cleaning of the RD-33 may be performed with a clean, dry lint-free cloth dampened slightly with
a mild non-abrasive cleaner. The area around the top terminals should be buffed dry with another
clean and totally dry cloth.
5.2
Repair
Due to the instruments complexity and use of surface mount component it is recommended that
Radian Research perform all repairs. We have excellent automated testers with which every
internal module can be tested quickly to original factory specifications. A final calibration and
quality control inspection to original factory specifications is performed quickly and thoroughly.
If the RD-33 should require repair then contact Radian Research or your local Radian Research
Representative and request a Return Material Authorization (RMA) number. You must provide
the model number and serial number as well as a detailed description of the problem.
5.3
Recalibration
Recalibration is recommended yearly. A periodic cross check against a Radian RD-21 or RD-22
or RD-33 is recommended to preclude the possibility of a failure in either. Prudence would dictate
having a dedicated RD-21 or RD-22 or RD-33 for cross check purposes. With the RD-21 or RD22 or RD-33 it is feasible to sample test units at various points as a “backup” test. In addition, it
is recommended that one take advantage of Radian’s recalibration service as a very cost effective
method to maintain traceability. Radian Research’s Calibration Laboratory maintains primary
transfer standards that are directly traceable to NIST. Radian Research’s Calibration Laboratory
also maintains several RS-703A Automated Calibration Systems as working secondary standards.
26
RD-33 Operations Manual
Service & Routine Maintenance
The RS-703A Automated Calibration System collects a data point on a RD Radian standard
every 5 (five) seconds on up to sixteen standards simultaneously, collecting literally thousands
of data points on an overnight run. In addition each RS-703A provides computer control over
an environmental chamber to ensure proper temperature range operation of the standard being
tested. Please contact Radian Research for further information on recalibration and recertification
services.
5.4
Fuse Replacement
In the unlikely event of fuse replacement, fuses are included and are accessible without disassembly. There are four fuses: three potential input and one auxiliary power. All fuses are located under
the red potential and auxiliary power inputs. Fuse replacement is performed as follows:
o
1. Remove the red terminal of the circuit with bad fuse by rotating 90 counterclockwise and then lift out the unit.
2. Remove the fuse by rotating it clockwise in the retaining screw.
3. Replace the fuse by rotating it clockwise in the retaining fuse.
o
4. Replace the terminal in the same orientation it was removed and rotate it 90
clockwise to lock in place.

The value of the Ke is dependent upon the meter Kh and the type of test conducted. The
Ke factor of any meter may be calculated by using the following constants.
Kh = Watthour constant. The number of watthours represented by one revolution
of the disk. Also called the disk constant.
Mp = Number of revolutions per pulse
Example Calculation:
Ke = (Kh) x (Mp); if Kh = 1.8 watthours per revolution and Mp = 1 revolution per
12 pulses, then,
Ke = (1.8 Wh/1 rev) x (1 rev/12 pulses) = (1.8 Wh/12 pulses) = 0.15 Wh/pulse
Step 6
Use the stylus and the arrow keys on the Meter Test screen to enter/select the Pulses per Kh, #
Seconds or Pulses, DUT Elements, Test Type, Standard Elements, Phase and State. Repeat Step 6

RR-DS Meter Disk Sensor
The RR-DS is a reflective pickup assembly used to sense the disk rotation of an induction type
meter. The pulses generated by the RM-DS are fed into the PICKUP port of the RD-33. 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-33. 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 circuitry 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.
