2.1 Unpacking the Instrument
2.2 Choice of the Site of Installation
On delivery please check that all the following components are present in the packing
box:
• HygroSmart I7000XP interchangeable sensor
• Certicate of calibration
• User’s manual
The installation site choice for the sensor, or the transmitter which incorporates the
sensor, must be made bearing in mind the effectiveness of air circulation. The point at
which the sensor is installed must be typical of the surrounding environment where the
measurements of relative humidity are to be taken.
The following should be avoided in keeping with good instrumentation practice:
• Installation location not representative of measuring conditions
• Installation location adjacent to high power sources
The operating envelope of the measurement probe is detailed in the following operating
