Valhalla 2720GS
U.S. Navy Accepted MECCA 31
Direct Voltage Standard
The Valhalla 272KS has been
approved and fully accepted as the
US. Navy MECCA ll Direct Voltage
Stantlard. In 1987 Valhalla provided
five first article 272065 DC Systems
to the US. Navy for compliance
testing to MIL-T-288QOC for EMI,
The 2720GS offers the best
accuracy of any DC calibrator on
the market, but we didn’t stop
there; our demanding internal
divider design has resulted in the
lowest temperature coefficient of
any DC Standard anywhere. So low
in fact, that our 1 .Gppm thirty day
accuracy is specified for & 6OC from
the calibration temperature.
RFI, accuracy, maintainability and
60 days of vibration failure analysis.
Not only were all five units fully
approved, but since 1987 Valhalla
has shipped over 125 systems which
the U.S. Navy accepted for the
MECCA II program.

The 2720GS delivers the
performance required to calibrate
the world’s most accurate 7% and
BY2 digit DVM’s yet does even
more. It also contains an on-board
autoranging digital nullmeter which
permits the 1720t;S to directly
calibrate our competition’s best DC
voltage calibrators. With our built-in
Auto NuII’~ function, one touch is
all that is required for the 2720CS
to achieve a null with the DC
source being calibrated. In the
~uto-NUN” mode the 272065
auxiliary read-out simultaneously
displays the error of the unit under
test (!JUT) out to 0.01 PPM
