Zero Wind Check
Configure your PC to run HyperTerminal and assemble the protective cover around the
WindObserver by inserting the reflector cases and the two halves of the ICC onto the IS
WindObserver. The protective cover must be secured together using for example Cable
ties/Tyraps or similar. Then:
1. Ensure that the IS WindObserver is set for a Continuous Polar or NMEA mode.
2. Record/View data.
In still air wind speed measurements should not exceed 0.03m/s. If wind speed exceeds
0.03m/s contact Gill Instruments.
Alignment Check
Ensure the Protective Cover is assembled correctly on the IS WindObserver. Using
HyperTerminal, enter Configuration Mode as described in Section 9.
Type in D6 and press Enter.
A typical report as shown below will be displayed.

If ‘Refer to Manual’ is shown check test temperature conditions are 17 to 23 deg C and
tested under zero wind condition.
If there has been no significant changes to the IS WindObserver head configuration then
*PASS* will confirm correct operation.
Alterations to the head geometry can result in a *FAIL* or ‘Insufficient Samples’
message. If this occurs please contact Gill Instruments.
