Doc. No. 1390-PS-0039
June 2016
Use of an Integrity Check Chamber (Optional item)
The ICC is designed to:
1.
Identify any gross changes in the head geometry that would affect the
performance.
2.
Provide a zero wind environment to confirm the WindObserver 65 zero calibration.
The ICC has been designed to be used in an indoor still air environment with an ambient
temperature between 17°C and 23°C. When conducting the test it is important that the ICC
is assembled on to the WindObserver 65 head and not touched or moved during the test.
This test is only valid if undertaken with an ICC purchased from Gill.
Note:- The Heater supply should be disconnected or turned off when using the ICC.
Zero Wind Check
Configure your PC to run HyperTerminal and assemble the ICC by inserting the reflector
cases and the two halves of the ICC onto the WindObserver 65. The ICC must be retained
using the strips provided. Then:
1.
Ensure that the WindObserver 65 is set in factory default mode. For Factory
default settings see section 8.4.
2.
Enter Measurement Mode and 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 ICC is assembled correctly on the WindObserver 65. Using HyperTerminal,
enter Configuration Mode as described in Section 8.
Enter D6.
A typical report as shown below will be displayed.
D6
ALIGMENT LIMITS: U=2424,2524
V=2434,2434
ALIGNMENT U:2474 *PASS*
ALIGNMENT V:2484 *PASS*
D6
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 WindObserver 65 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.
10.7.
Returning Units
If the unit has to be returned, it should be carefully packed in the original packaging and
returned to your authorised Gill distributor, with a full description of the fault condition.
