17.8.6 SENSOR CALIBRATION 
To ensure reliable operation of the system the SENSIT sensors should be calibrated 
before commissioning. Calibration values can be set for the magnetic detection in 
each axis (x, y and z). Default calibration values are 50 mGauss in each axis. The 
default value for the IR sensitivity is 9, the maximum. The IR sensitivity is only 
lowered in case of a ceiling or other coverage of the SENSIT sensors. 
  
 
Figure 68: SENSIT sensor calibration 
SENSIT nodes can be calibrated individually. This by entering the Node ID of the 
specific sensor you want to calibrate into the field 'Calibrate node number'. 
 
Alternatively you can calibrate all nodes or the nodes from a specific parking lot. 
When you click 'Calibrate all nodes' all SENSIT sensors in the network will 
automatically be calibrated.
 
Click the 'Calibrate' button to start the calibration. In the menu an update message 
will start to keep you update on progress. 
 
Incorrect occupied spaces can be indicated if a vehicle parked in the neighboring 
parking space activates the magnetic sensor. If the percentage of incorrect occupied 
(so actually free) is too high over the parking lot, the magnetic values can be 
adjusted by selecting a higher value e.g. 60 mGauss. If the percentage of incorrect 
free (actually occupied) spaces is too high the sensitivity of the magnetic threshold 
can be reduced to lower value e.g. 40 mGauss. 
 
17.8.7 DISPLAY 
 
Display Configuration 
The 'Display configuration' screen allows you to control a display via the node 
network. This without any physical communication wiring. Only a power supply is 
required. The communication with a display is realized via a display node. Note that 
this functionality is only available for specific displays. Contact Nedap for more 
information. The display node is part of the network and can therefore communicate 
wirelessly via the node network. A maximum number of 2 displays can be controlled 
in a wireless mesh network of 500 sensors. Use of more displays will increase the 
communication latency. 
 
The update of a Display can be enabled and the update interval can be set. A choice 
can be made either to subtract the full threshold from the display value on forehand 
or to set the display at zero when the threshold value is reached. 
Note 
The SENSIT nodes can only 
be calibrated when the 
specific bay and 
neighboring bays are not 
occupied by vehicle. When 
all SENSIT nodes need to be 
calibrated the parking lot 
must be completely empty. 
 
Note 
Individual sensor can also 
easily been calibrated via 
the Maps.
