Portable Field Standards
RM-10 Metronic Portable Watthour Standard
 | > +/- 0.05% Maximum Error The Radian Research RM-10 Metronic |
The RM-10 is totally autoranging on the potential input, current input and
auxiliary power input. Totally autoranging inputs, a feature pioneered by
Radian, make it impossible to damage the unit by applying a signal to the
wrong input. The three summing current inputs can be used to perform
closed link testing. A maximum test current of 150 Amps can be used
when paralleling the three 50 Amp inputs.
The RM-10 provides a true watthour display with a Kh of 1 for its entire
operating range. This feature, introduced by Radian, allows for a much
simpler percent registration calculation. Models with VARhour and Qhour
capabilities are available for testing the newer multifunction solid state
meters.

RD-31 Dytronic Three Phase Standard
 | > 4 Quadrant Simultaneous |
Product highlights: The Radian RD-31 Three-phase Electricity
Reference Standard achieves a level of accuracy and performance never
before available in a portable standard. The RD-31 has a typical accuracy
of 0.005% with a maximum worst case accuracy of 0.02% for all
measurement functions across its entire voltage and current operating
range. This worst case accuracy specification includes the variables of
stability, power factor, traceability uncertainty and test system errors.
The RD-31 utilizes Radian's new Dytronic measurement technology
consisting of a Radian designed Integrating Analog to Digital Signal
Converter. The RD-31's 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 standard.

Primary Transfer
Standards
RD-22 Dytronic Primary
Reference Standard
> +/- 0.01% Maximum Accuracy
> Radian Designed Intergrating A/D
Signal Converter
> 4 Quadrant Simultaneous
Multimeasurement
> Input for External DC Reference
> Harmonic Waveform Analysis
> Built-in Comparator
> PC Interface
> Analog Sense
The RD-22 Primary Transfer
Standard represents the
state-of-the-art technology in a
commercially available true DC to
AC accuracy transfer reference.
The RD-22 has typical accuracies
within the measurement limits of
traceability. High accuracy and
precision provides repeatabilities in
the range of 0.00001%.
The RD-22 utilizes Radian's new
enhanced Dytronic measurement
technology consisting of a Radian
designed Integrating Analog to
Digital Signal Converter based upon
a charge-balance conversion
principle. In addition, the RD-22
uses a new Radian electronically
compensated autoranging external
current comparator transformer
along with Radian's renowned
electronically compensated voltage
input transformer and a hermetically
sealed reference set to provide the
highest degree of accuracy, stability
and versatility ever offered in a
primary transfer standard.
The RD-22 can be used to transfer
accurate and traceable
measurements from Radian
Research's calibration laboratory.
Alternatively, it can be calibrated
directly by a National metrology
laboratory, such as the National
Institute of Standards and
Technology (NIST). The RD-22 can
also be tested by using external DC
primary reference sets of voltage,
current, and time. These external
DC references can be compared
directly to the RD-22's internal
reference sets. Additionally, the
RD-22 can be used as the active
reference to the RS-703A Syntron
Signal Source to provide a complete
AC metrology reference system.
