Competent Partner
GMC-I Messtechnik GmbH is certified in accordance with
DINENISO9001.
Our DAkkS calibration laboratory is accredited by the Deutsche
Akkreditierungsstelle GmbH (German accreditation body) under
registration number D-K-15080-01-01 in accordance with
DIN EN ISO/IEC 17025.
We offer a complete range of expertise in the field of metrology:
from test reports and proprietary calibration certificates right on up to
DAkkS calibration certificates.
Our spectrum of offerings is rounded out with free test equipment
management.
An on-site DAkkS calibration station is an integral part of our service
department. If errors are discovered during calibration, our spe-
cialized personnel are capable of completing repairs using original
replacement parts.
As a full service calibration laboratory, we can calibrate instru-
ments from other manufacturers as well.
23 Recalibration
The measuring tasks performed with your instrument, and the
stressing it’s subjected to, influence aging of its components and
may result in deviation from the specified levels of accuracy.
In the case of strict measuring accuracy requirements, as well as
in the event of use at construction sites with frequent stress due
to transport and considerable temperature fluctuation, we recom-
mend a relatively short calibration interval of once per year. If your
instrument is used primarily in the laboratory and indoors without
considerable climatic or mechanical stressing, a calibration inter-
val of once every 2 to 3 years is sufficient as a rule.
During recalibration at an accredited calibration laboratory (DIN
EN ISO/IEC 17025), deviations from traceable standards demon-
strated by your measuring instrument are documented. Ascer-
tained deviations are used to correct displayed values during later
use of the instrument.
We would be happy to perform DAkkS or factory calibration for
you at our calibration laboratory. Further information is available at
our website:
www.gossenmetrawatt.com (→ Company → DAkkS Calibration
Center or → FAQs → Questions and Answers Regarding Calibra-
tion).
Recalibration of your instrument at regular intervals is essential for
the fulfillment of requirements according to quality management
systems per DIN EN ISO 9001.
* Examination of the specification, as well as adjustment, are not included in calibra-
tion. However, in the case of our own products, any required adjustment is per-
formed and adherence to the specification is confirmed.
24 Software
Internal test instrument software can be updated via the USB port
with the help of a PC and an interface cable.
The firmware with the desired software version is transmitted to
the test instrument via the USB port with the help of a firmware
update tool. Previously installed software is overwritten in the pro-
cess.
As a registered user (if you’ve registered your test instrument),
you’re entitled to download the firmware update tool and the cur-
rent firmware version free of charge from the myGMC page at
www.gossenmetrawatt.com.
You’ll also find operating instructions for the firmware update tool
here.
Downloading Procedure
➭ Establish a connection between the PC and the test instru-
ment.
➭ Switch the PC and the test instrument on.
