CHAPTER 4
MAINTENANCE
This chapter provides information that is needed in basic
maintenance of WAT12 Analog Wind Transmitter.
Periodic Maintenance
Visual Checking
Check every 1 to 2 years that the printed circuit board is not
corrored.
Testing Proper Operation
For easy testing and adjustment, reference signals are
provided for the two output channels. For instance, by
inserting a jumper plug, an output can be forced to the full
scale or zero level. Hence a readout device can be easily
adjusted to comply with the transmitter output. Inside the
transmitter box there is an instruction label, showing all the
useful jumper combinations for output scale, measurement
range, and testing.
