o
Adjust the transmitter using the temperature and / or humidity calibration points present in the
transmitter memory.
对变送器做单点或多点校准（湿度和

或温度），对应一个已知参考环境。校准点保存在变送器的存储器内。
The procedure for calibrating and adjusting a probe, a transmitter or any other device with the HP23 is
described in the Maintenance chapter of this manual.

: the HP23 uses an algorithm to accelerate the water activity measurement
and provides a result in typically 5 minutes. The measurement ends automatically and the
display is frozen. When temperature conditions are stable (both at the product and probe), the
value measured with the AwQuick mode is generally within ± 0.005 aw of the value that would
be obtained by waiting for full equilibration of the product and probe.
