CHAPTER 5 MAINTENANCE

5-1

PERIODIC MAINTENANCE SCHEDULE

Routine maintenance should be performed on the WEATHERPAK

to ensure that the overall system and its sensors are working and performing within specification. The actual

services vary based on the sensors installed on your WEATHERPAK

MTR should have the compass, air temperature, relative humidity, and barometric pressure sensors tested to

their stated specifications. (The wind monitor and optional gamma detector do not require periodic calibration or

maintenance.) In addition, the entire WEATHERPAK

conforming variances. Please contact Coastal Environmental Systems' Service Department (800-488-8291

x157) for more information.

TROUBLESHOOTING

Do not take the WEATHERPAK

following procedures do not solve the problem, call Coastal Environmental Systems' Service Department (800-

488-8291 x157).

5-2.1

The WEATHERPAK

When completely assembled, the WEATHERPAK

and begins sampling the atmospheric conditions; it then transmits weather data every 30 seconds. If it

does not, check the following:

•

Confirm the WEATHERPAK

•

Check the batteries in the tower. The red LED voltage indicator light on the tripod tower will remain

illuminated when the battery voltage is higher than 10.7 VDC. If the LED indicator is not illuminated or if it is

flashing, replace the batteries with fresh alkaline D-cells. The precise battery voltage can be found by

viewing the Weatherpak Status screen on the Receiver/Display. When replacing tower batteries, use only

high quality alkaline batteries. Do not use rechargeable or bargain batteries.

•

Check the fuse. There is an in-line fuse holder located in the junction box at the top of the tripod tower.

Access the fuse by removing the two screws on the junction box cover. If the fuse is blown, replace with a

3AGC fuse. If the fuse blows repeatedly, contact the Coastal Environmental System's Service Department.

See Section 5-3 "Replacing Tower Batteries and Fuse".

5-2.2

The Receiver/Display

The green power indicator light, located in the center of the "On/Off" button, should be on and the

display should be illuminated shortly after the "On/Off" button is pressed. If this is not the case, check

the following:
