When using high quality sensors and system, most of the routine

maintenance tasks can be performed at the installation site. Some

instruments and advanced calibrations and refurbishments require the

sensor to be returned to the laboratory for proper calibration. When

system components need to be brought in from the field, the best

procedure is to maintain an inventory of spare components. The user

can then exchange a component with a calibrated component or sensor

during a single visit. This is the case especially with sensors that must

be returned to the manufacturer for calibration.

Before the maintenance actions, certain preparations must be made in

order to make the work successful:

- Obtain information on how the site has been functioning before the

scheduled maintenance.

- Obtain information on what maintenance tasks were completed

during the previous maintenance procedure.

- Make sure that you have all the necessary tools available. The

required set of tools depends on the system configuration, however

the minimum is listed below:

- A laptop PC with multiple fully charged batteries.

- The latest operational versions of the MAWS operating

software version, MAWS Lizard Setup Software, and MAWS

Terminal software.

- The setup file that is used at the particular station to be

maintained.

- All the necessary system documentation.

- MAWS Terminal cable (QMZ101).

- Hand held tools; screw drivers, wrenches, pliers, wire cutters,

and insulation strippers.

- Digital multimeter.

- Clean cloth, cleaning solution, and cleaning brush.

- Lubricant.

- Anti-seize compound.

- Safety harness, if tower climbing is required.

- All the necessary parts to be changed regularly.

- Make a list of all the sensors requiring replacement with

refurbished and calibrated units.
