Raise the value measured by Querx to a higher level
by increasing the measured parameter (i.e.
temperature, humidity or air pressure) and measure
it with the reference device. Enter the reference

The Querx PT and Querx WLAN PT models can be
calibrated without a reference device, if they are fitted
with a waterproof sensor. The freezing point and boiling
point of water can be used as reference values instead
of determining them with a calibrated device. Dip the
sensor into ice water and enter a reference value of 0,
in order to adjust the lower reference value. Repeat the
measurement after dipping the sensor into boiling
water and entering a reference value of 100, in order to
calibrate the upper reference value.
⚠
Attention
This option is only applicable for Querx variants
equipped with a waterproof Pt100 sensor!
