Adjustment
Adjustment means action resulting in setting WiFi sensor to the state, when
its actual measurement accuracy is identical or better than measurement
accuracy specified in instruction manual. Adjustment is possible only for
measured values (temperature, relative humidity, CO
2
concentration
or pressure). For this operation, as well as for the calibration, a special
equipment for constant temperature, relative humidity, CO
2
concentration or
pressure generation is needed. Device adjustment is performed by placing
the adjusted device to the calibration chamber and by consequent
assignment of measured values to standard reading by means of the
WifiSensorUtility software.
WiFi sensor Adjustment Conditions
Any unqualified entry into the instrument adjustment mode to may rewrite the
existing calibration constants. It can cause that the instrument will be unable
to measure!
Follow recommendation and conditions for calibration during the device
adjustment.
Adjustment of the measured values should be done in two point. These
points should be as far apart as possible within the required measuring
range. In some cases, the calibration can be made at one point.
When adjusting the relative humidity, it is not recommended to use an upper
adjustment point higher than 90 %RH. Recommended values for relative
humidity adjustment are (10
– 20) %RH and (70 – 80) %RH.
After the adjustment, it is always necessary to verify the correct
measurement accuracy of the newly adjusted device (see the
).
