MetroVal is an easy automatic or manual
calibration program and metrology analysis tool. For
uncertainty, prediction and interval analysis it uses
extended functionality of the Evaluator
programs as integrated modules. For more information,
check the attached pdf presentation.
MetroVal is used by Metrology labs
to calibrate or prepare uncertainty budgets and
calibration procedures from one central point.
The Calibration procedure
looks like a simple table. It can be edited
manually or generated automatically and
linked to the associated uncertainty budget
tables. This approach enables non-programmers to
prepare calibration procedures and review them in
For automated calibrations a
subroutine sequencer is used. For automated
calibration VISA drivers should be installed. If
VISA is not installed, only manual calibrations
are possible. Newton Metrology Ltd is not
licensing or distributing VISA. Contact companies
such as Agilent Technologies to obtain VISA
drivers. VISA allows for calibrations using
IEEE488, USB, LAN and RS232 communications with
The procedure table is
read line by line and tells the program
which modules to run, which data to use, which
methods to use to compute the uncertainties and
how to generate the calibration report.
Also, it runs segments of the command sequencer as
subroutines. A calibration template is generated
that facilitates overview of the measured
uncertainty module can estimate measurement
uncertainties per ISO GUM or by Monte-Carlo
simulation directly from the measurement equation.
The Prediction module can estimate present values
and uncertainties of measurement standards from
their past calibrations.
Being linked to past
calibrations data, the program can estimate and
use drifts (over time or over number of uses) as
uncertainty components in the uncertainty budgets.
This has the advantage of having the measurement
standards uncertainties and deviations updated and
used in real time.
The calibration points and
uncertainties can be complex numbers.
A simple result report
editor is used to generate result table that
complies with accreditation requirements. The
certificate cover page is not generated since it
is usually prepared by specific accreditation
requirements using a word processor.
Like all Newton Metrology
programs, MetroVal Complies with ISO/IEC 17025,
the GUM (with supplements 1 and 2) and ILAC
G8 document for compliance with
specifications. Predictions comply with ILAC G24 /
OIML D 10. PFA can also be computed with an ON or
OFF directives in the calibration procedure per
MetroVal can run using
information in an INI file and structured text
file. It is possible to run MetroVal from another
program using the INI file name as parameter.
