Together with the array of measuring instruments we offer and
the specialised knowledge of our engineers and technical staff, here
is a list of terms commonly used in the field of measuring
instruments to help you before making a purchase:
Adjust: allows professionals to fine tune
the device to ensure the most accurate readings, particularly a
function in devices such as scales.
Calibration: Official verification that the measuring instrument
responds acceptably to predetermined error limits.
Calibrate: To determine the systematic deviation of
of the meter's display with respect to the true value of the unit
being measured.
Calibration certificate: Documenting the relative characteristics
in relation to a technical measurement of a measuring device and how
it operates in conjunction with national standards.
DIN EN ISO 9001 certification:this
certification signifies that a company has demonstrated that they have
adapted their entire management system to meet the DIN EN ISO 9001
standard of quality. After inspection by the relevant authorities, the
company is awarded a DIN EN ISO 9001 certificate of quality according to
the management system they have in place.
This certificate is completely different from that of the ENAC
calibration certificate which relates to the relative characteristics of
the technical measurements made by measuring instruments. Certification
according to DIN EN ISO 9001 is also not identical to an accreditation
for as yet there is no accords here as to the effects of international
recognition.
Factory calibration certificate: Factory
calibration certificates are issued with standards that are that are a
result of subjecting the measuring device to rigourous quality control
measures. Quality is assured as the instruments ued for quality control
are regularly maintained to ensure the highest level of accuracy.
The measuring instruments are then adjusted using a quality control
device and calibrated within the factory.
Calibration interval: To ensure that correct measurements are being taken, the device
should be calibrated periodically. This period of time is known as
the calibration interval. It's impossible to accurately determine
when a device will require calibration, however, it always helps to
have a guide, and here are a few key things to consider as an
indication:
Measurement value and the permitted range of tolerance.
Performance of the measuring instruments.
Frequency of use.
Operating conditions.
Stability of previous calibrations.
Accuracy required for the measuring instruments.
Quality control requirements of the company.
This means
that the same user should have responsibility during a calibration
interval. Measurement
margin of error: Margin of error of readings with respect to real
measurement value. Factory
calibration certificate:
These certificates are issued by accredited manufacturers that can
ensure the devices meet the stringent requirements for accuracy and
reliability.
Conformity certificate: Compatibility
between two devices and official documented approval during
calibration by the notifying body issuing the conformity certificate.
Certificate of revision:
Certified with the factory confirming that the product being
delivered meets the product specifications. (data sheet).
Declaration of conformity:
The document for declaring conformity that a device meets CE
requirements
(los medidores electrónicos van siempre unidos al distintito CE).
Measurement of deviation: Deviation on the
display of the measurement in relation to the real measurement value.
ENAC: The "ENAC"
calibration service is a union of technical measurement laboratories
that are accreditied to a determined parameters. They are highly
compotent in the field of technical measurement. An ENAC accredited
laboratory has the right to issue internationally established
calibration certificates for these parameters and measuring
instruments. ENAC certificates are valid in many countries around
the world, including those within the European Union. In the
paragraph
Meters - ENAC you will find more information.
Operating temperature: The temperature
range that the instrument can be used reliably. If the device are
used outside of this range, errors can be produced in measurements.
If temperatures are extreme the internal electronics of the
measuring instrument can be destroyed.
Margin of error: Indicates the range of error possible for
any given value displayed by the device.
Overload /overcharge indicator: Symbol or character displayed
by the device to indicate an "overload" which is typically shown as
"OL". An overload has the potential to damage the measuring
instrument beyond repair.
Thermal influence: This is physically conditioned and can
only be corrected via incorporated measurement compensations. Some
measuring instruments come with automatic temperature compensation
available and others have it mechanically. Mechanical compensation
is given to represent the actual temperature, such as an adjustment
wheel or by indicating it on the display.
Measuring instruments: These are devices that give visual
representation of data and allow for certain parameters to be
measured or calculated and displayed in specific unit types.
They can be electronic or mechanical devices and can be used in
conjunction with a computer.
Interface: Also known as a connection port which allows for the
measuring instrument to be connected to a computer for data transfer
and analysis.
ISO 9000:
System of quality management by way of DIN Standards to identify a
companies level of quality control. It's full denomination is DIN EN ISO
9000.
Legibility: The smallest numerical value legible on the device's
display.
Data
Logger / Data Registers: Many devices have an internal memory
for measurement values. This memory can becan be used in situ
to store readings or programmed to work in conjunction with a
computer to recover data for further analysis. As such, devices
equiped with a data logger, can function independantly without
someone monitoring it.
OIML:
"Organisation Internationale de Métrologie Légale". Regulates
the relative interests in technical measurement in legal
contrastability (meteorology). Link to Meters in the OIML.
LCD (Liquid Crystal Display): The display contains liquid
crystal which reacts to the anisotropic conductivity of liquid
crystals. The displays are not self-lit in measuring instruments.
LED display (Light Emitting Diode): Functioning element of
the digital display. It utilises its own light source from luminous
and luminescent diodes. The display is self-lighting.
Accuracy: The physical form of the meters is quite varied.
Independantly of this, they can be characterised according to their
construction and function and for the object they are being employed
to measure. More concretely, they are differenciated by
characteristics such as their accuracy and maximum load.
CEM: Ths is the federal authority is competent in legal
meteorology in Spain (CEM).
Connection port: Primarily an RS-232C to connect to a
computer.
Response time: Period of time from connecting the meter until
the measurement result is shown on the display. This refers to the
combination of meter, sensor, probe or electrode according to the
parameter that is going to be measured. As such, a lot of times, it
is not related to the meter itself but to that of the sensor that it
uses.
Repeatability: This is the process that indicates that the
measurement shown by the device can be comparable to one or more
measurements according to the national standard for the parameter
being measured. Thanks to the exsisting agreement with "CEM"
and to the DIN EN 45001 quality standard there is no need to
independantly demonstrate the devices repeatability.
Standard deviation: Measurement of
the coincendences in the repetiton of measurements taken under the
same circumstances.
Resolution: Minimum width of the
character presented on the display of a measuring instruement, also
referred to as a digit.
Response time: Duration of time required
for the device to show the measurement value on its display after
being connected.
Ingress protection (IP): The higher
the numerical value of IP, the less dust and water that is possible
to penetrate the enclosure of the measuring instrument.
Margin of error: Each device display
has a tolerance to physical conditions. This tolerance defines
the maximum deviation permitted by the display and is indicated in "plus" or
"minus".
Validation:
Documented test that a process or procedure meets appropriate safety
levels required to perform a specific task.

PCE Group has
tested its measuring instruments in the Antarctic. With the intention of
checking if our equipment has the capacity to resist extreme
temperatures, and to see if small changes occur in the joints of the
thermal insulation that might creates a micro-climate within the
interior of the device. Teams conduct astronomical, geological,
ornithological and environmental experiments with great success, thanks
to equipment such as measuring instruments for ozono, for pH,
ultraviolet light, airflow meters, dosimeters, etc.
The Antarctic is a natural
laboratory that contains certain properties that are closely related to
the origins of the Earth and the Solar System. It's obvious the role the
antaric ice plays, thanks
to the microscopic pockets of air that remain trapped in layers of ice,
in the estimation of different climatic changes
(glaciaciones) that have occurred upon the Earth's surface over time.
Contributing factors of climatic change are the greenhouse effect, as a
result of CO2 emissions, and the depletion of the ozone layer in the
upper atmosphere, permitting UVB radiation to reach the planet's surface.
This has been caused, in part, by increased human industrialisaton in
the last decades. As a result, the Earth naturally makes adjustments to
effect climate change, these cyclical movements, precession and nutation,
that are made to the Earth's position in realtion to the sun, as well as
its own cycles and evolution which are evidenced by changes in the
Earth's atmosphere, marine currents, and external forces such as
asteroids. The history of the Earth's climate allows scientists to
determine which geographical area has been affected by climate changes.
It's a mistake to beleive that a particular geographical region has
always been under the same climatic conditions through its history.
What's certain is that an atmospheric change on the planet will result
in vast changes for people today and this is the reason why so many
people are afraid of climate change.
