Radian Research, Inc.
RD-20 Dytronic Portable Single-Phase Standard
INTUITIVE USER INTERFACE
The RD-20’s LCD and fi ve-button keypad provides a direct interface to the end
user while the RD-20’s RS-232 port, utilized with the applicable software, allows
for remote PC control and confi guration of the RD-20. Utilizing the fi ve-button
keypad and observing the LCD, the user is able to scroll through the various mea-
surement functions of the RD-20 and toggle between the different menu screens.
The amount of measurement information and the number of menu screens viewable
is determined by the model number of the RD-20.
MENU SCREENS
The key menu screens are the Measurement Screens, Run Test Screen, Harmonics
Screen, and Setup Screen.
The Measurement Screens will display the measurement functions the RD-20 sup-
ports. There are different screens for Instantaneous Measurements, Accumulating
Measurements, and Minimum & Maximum Measurements. Using the keypad, it
is very simple to toggle between the various measurement screens and to scroll
through the various measurement functions.

Worst Case = +/- 0.04% The Main Menu Screen allows users to gain access to the specifi c functionality of
their RD-20. From the Main Menu, the user may select to run a meter or standard
test, perform harmonics analysis, set-up/confi gure their RD-20, perform a self test,

and review information pertinent to their RD-20.
PRODUCT HIGHLIGHTS: The Radian RD-20 Single-phase Electricity
Reference Standard is one of the most versatile reference instruments ever. The
RD-20 has a typical accuracy of 0.01% for all measurement functions across
its entire operating range, with a maximum worst case accuracy of 0.04%. This
worst case accuracy specifi cation includes the variables of stability, power factor,
traceability uncertainty and test system errors. The Run Test Screen allows the user to select the type of test they would like to
run and then to enter the different variables for that specifi c test.
The RD-20 utilizes Radian’s new Dytronic measurement technology consisting
of a Radian designed Integrating Analog to Digital Signal Converter. Unlike
off-the-shelf A/D Converters used in other instruments, Radian’s A/D Converter
is specifi cally designed and optimized for power and energy measurement. This
unique design makes the RD-20 absolutely unsurpassed in its ability to accurately
measure “real world” waveforms. The RD-20’s A/D Converter is combined with
Radian’s renowned electronically compensated voltage and current input trans-
formers and a hermetically sealed reference set to provide the highest degree of
accuracy, stability and versatility offered in a portable single-phase standard. In the Harmonics Screen the user may select to view voltage or amperage harmonics,
