Adjustment and Calibration
Integrated sensors, as used in the TH and THP models,
are usually produced with high tolerances. These
sensors are calibrated at our works, in order to achieve
the required accuracy.
Platinum temperature sensors, which are used with the
PT models, are produced according to accuracy grades
and do not need to be calibrated.
We offer DAkkS calibration certificates as an accessory
for all devices for any applications that require
traceably calibrated monitoring equipment, for quality
management purposes, for instance.
Further information on this is available at
. We
are also happy to advise you personally.
egnite Querx offers the possibility of calibrating the
sensor’s measurements, as well as adjusting them, if
required.
In common practice, it may occur that Querx does not
display the true, current values but diverges from them
within certain limits. The feature
Adjustment and
Calibration
serves to correct any data gathered by
Querx that diverges from the actual values and make it
correspond to the real measurements as closely as
possible.
In order to determine these actual values, you will
require a reference device whose measurements you
can trust. Ideally, this should be a calibrated device
with a known standard deviation.
11.7.1 Manual Adjustment with Offset
In this case, a fixed correction value, the so-called
offset, is determined in the configuration area. The
offset is a fixed value that is added to any value
measured by the sensor.
In order to adjust your Querx by this method, please
take the following steps:
Establish the required offset to correct the measuring
error. This value is determined by comparing the value
