Post-installation
The module is delivered with the range set at 0.5 to 8 m/sec (100 to 1575 ft/min). If
jumper SW1 is removed on the printed circuit board, the range 0.5 to 16 m/sec (100
to 3150 ft/min) is obtained.
Maintenance
As the thermal measuring principle is based on the cooling principle of the air, dirt
accumulation on the sensor will reduce the measuring accuracy. If the transmitter is
used in dirty air, the sensor head should be cleaned at suitable intervals.
