792A AC/DC Transfer Standard Fluke Corporation 3
Performance
specifications
There are three tables of uncer-
tainties included for the 792A.
The first two are absolute and
traceable to the National Insti-
tute of Standards and Technol-
ogy (NIST). Absolute uncertainty
includes time stability, tempera-
ture, line and load regulation,
and the traceability provided by
NIST (see Fluke application note
B0205A, Establishing Traceabil-
ity for a High Performance
AC/DC Transfer Standard). The
third table, Relative Uncertainty,
includes time stability, tempera-
ture, line and load regulation,
but not the traceability to
national or external standards.
These uncertainties apply
when the calibration report,
provided with the 792A, is used
to correct the response of the
transfer standard.
2 Fluke Corporation 792A AC/DC Transfer Standard
The RMS Sensor is designed
to be rugged and reliable. Each
is built to exacting standards by
the Fluke Microelectronics Op-
eration to maintain quality and
consistency, part after part.
Fully traceable
performance
Each 792A is shipped from
Fluke with documented trace-
ability to the US National Insti-
tute of Standards and Technol-
ogy (NIST). Included is a table
of correction factors and uncer-
tainties for measured ac/dc
differences.
To support the traceability
requirements for an instrument
as accurate as the 792A, the
Fluke Metrology Department
developed a unique system to
transfer NIST values to the 792A
production environment. This
system is based on proven tech-
niques developed to maintain a
732A direct voltage standard to
within a few parts in 100 million.
Statistical treatment of data
resulting from successive
intercomparisons of virtually
identical 792As is used to mini-
mize transfer uncertainties. To
achieve even higher perfor-
mance, you can have the trans-
fer uncertainties of your 792A
assigned directly by NIST, or
other national standards organi-
zations. For more information,
request the application note
titled Establishing Traceability
for a High Performance AC/DC
Transfer Standard.
Periodic calibration and
recertification is available from
Fluke. This service repeats the
original calibration procedure.
A new table of correction factors
and undertainties for measured
ac/dc differences is returned
with your instrument. Order
792A-000.
Description
The 792A consists of four units.
The Transfer Unit is the main
analog component of the 792A
for the 20 mV to 220V ranges.
Stainless Steel Type-N connec-
tors assure low signal loss and
high measurement repeatability.
The separate Power Pack unit
permits the Transfer Unit and
1000V Range Resistor to be
shipped independently for
calibration. The 1000V Range
Resistor isolates the heat gener-
ated at high voltages outside
the main Transfer Unit. The
Range Resistor has a low tem-
perature coefficient, stabilizes
quickly and exhibits small ac/dc
differences. The Transfer Switch
provides for switching between
the ac and dc inputs.
Each 792A is shipped from
the factory traceable to NIST
standards. Each 792A also
includes a table of correction
factors and uncertainties for
measured ac/dc differences.
The 792A consists of four main components: The Transfer Unit, Power Pack, 1000V Range
Resistor and Transfer Switch.
Each 792A includes a table of correction factors and uncertainties for measured ac/dc differences.
