MAINTENANCE & FAULT-FINDING
8.1.
Cleaning and Handling
Ideally when installing the unit handle with lint free gloves and degrease the unit to reduce the build-up of
deposits.
8.2.
Servicing
There are no moving parts requiring routine maintenance.
Opening the unit or breaking the security seal will void the warranty and the calibration.
In the event of failure, prior to returning the unit to your authorised Gill distributor, it is recommended
that:
All cables and connectors are checked for continuity, bad contacts, corrosion etc.
A bench test is carried out.
Contact your supplier for advice if failure persists.
8.2.1 Precipitation Sensor
GMX100, 240, 400, 541and 600 Solid State Rain Gauge
Users/distributors should clean the plastic dome with a soft, lint free cloth and where necessary with a
non-aggressive cleaning solution ideally once a week. Where this is not possible, cleaning should be done
during regularly-scheduled visits to the sensor and site. It is recommended that the rain gauge sensor
should be cleaned every 3 months as a minimum.
Users can check operation of the rain gauge by performing a simple test of functionality by spraying some
water using a mist nozzle similar to that used in many households for watering plants. The MaxiMet rain
gauge should register incremental rain fall when sprayed with water.
GMX 531 Kalyx Tipping Bucket Rain Gauge (similar checks should be carried
out on other tipping bucket rain gauges)
Maintenance periods are site dependant but periodic maintenance every 2-3 months should be
considered. To ensure reliable and accurate measurements, we recommend that the following checks are
carried out at each visit to the rain gauge.
Note:
If the gauge is still connected to a data logger and logger is operating, care must be taken to avoid
tipping the bucket when carrying out the following operations.
