Weekly Tasks; Infrequent Tasks; Minor Maintenance - Kipp & Zonen Brewer Mk III Operator's Manual

5.2

WEEKLY TASKS

There are a number of tasks which should be performed and results recorded at least weekly.
1. Steps per Revolution (Section 6.14)
2. Solar Siting (Section 7)
5.3

INFREQUENT TASKS

This section deals with true 'infrequent' tasks, as well as those that are more for the integrity of the
data than for the operation of the Brewer. The timing of many of these tasks is usually determined
by the "Scientific Authority" of the observation site.
1. UV Stability Check (Section 6)
2. Mechanical Checks
3. UV Calibration
4. Ozone Calibration
5.4

MINOR MAINTENANCE

Routine maintenance deals with periodic checks and adjustments that the Operator should do to
ensure correct operation of the Brewer. These items are not failures, but may lead to failures, or
result in poor data if not attended to.
Desiccant Changes
Moisture is one of the worst enemies of the Brewer and can cause damage to the Optics which
often can be corrected only by returning the Brewer to the factory for parts replacement and
recalibration.
There are two desiccant systems in the Brewer - the desiccant cartridge 'breather' and the loose, or
bagged desiccant.
The desiccant cartrige is intended to remove moisture from the air drawn into the Brewer as
temperature changes. This container can be inspected from the underside of the Brewer base by
removing two 'thumbscrews. If the desiccant is no longer Blue, then it requires changing.
Loose or bagged desiccant is intended to remove moisture from inside the Brewer enclosure.
If the Brewer is equipped with a Moisture Sensor, then the Moisture Index is displayed on the
Computer Display. The maximum safe level for the Moisture Index is 10.
If the Brewer is not equipped with a Moisture Sensor, then Humidity Sensors placed beneath the
Brewer Viewing Window should be inspected regularly. If the 40% indicator starts to turn Pink, the
moisture is approaching the danger level.
If either of the two potentially dangerous conditions of moisture is viewed, then the desiccant in the
Brewer enclosure should be changed.
The desiccant container mounted in the rear of the Spectrometer should be inspected each time
the Brewer cover is removed, and the desiccant replaced whenever it is observed that the indicator
is in the 40% region.
