measuring device or
the sensors and ensure that the delivery is complete.
→ In the event of transport damage, the packaging material must be retained
and the supplier must be informed immediately.
4.2 Description
The ALMEMO
®
measuring system for calibrating climatic chambers consists of an
ALMEMO
®
precision measuring device of device version V7 (hereinafter referred to
as the ALMEMO
®
measuring device), various sensors, the AMR WinControl
software, an assistant for convenient evaluation of the measured values in the AMR
WinControl software and an additional protocol for direct control of climatic
chambers in AMR WinControl during calibration.
When ordering the programming of the sensors for climatic chamber measurement,
an overview of the measuring point assignment is supplied. It is tailored to the
respective configuration for the customer and shows which sensors are to be used
at which measuring locations and which measuring point the ALMEMO
®
measuring
device should use for that. The ALMEMO
®
connectors of the sensors are
preconfigured to match the measuring point assignment.
The calibration method described is used to calibrate climatic chambers in
accordance with the DKD-R 5-7 guideline with regard to ambient temperature and
relative humidity or with regard to ambient temperature only.
Calibration of the climatic chamber determines the deviation of the values displayed
by the climatic chamber from the actual climatic parameters of air temperature and
relative humidity in the useful volume. For this purpose, the useful volume is
stretched out in the climatic chamber with the temperature sensors (normally eight
sensors) in the form of a cuboid and the psychrometer is positioned in the center of
the useful volume. The humidity values in the corner points are calculated from the
humidity in the center and the temperature values in the corner points.
