bought as separate items then the console and ISS will show as, for example (but obviously depending on
the exact part), 6312UK and 6322OV respectively. There is no functional difference between eg a 6152UK
console and a 6312UK console, the label is simply indicating whether the part was originally part of a
complete station or not.
Second, it is important that the complete product number (including letters at the end) is noted. A 6312
console is different from a 6312UK console and the two cannot necessarily substitute for one another.
Note: Only main components have a label showing a product number. Smaller sensor parts and sub-
assemblies will all have Davis numbers, but the spare parts list is needed to identify these. It’s often the
case that a part built around a small PCB board will be seen to have part and version numbers on the board,
but these are typically the part numbers of the bare unpopulated PCB board itself and are of no use in
identifying the part as a whole. Don’t be misled by these PCB numbers.
Manufacturing Code
The Manufacturing Code (or Mfg Code) is a unique identifier for each main component of the weather
station and is essentially the same as a serial number for that unit. The Mfg code contains the date of
manufacture of each unit together with some additional information that denotes, for example, the version of
that particular part. (Davis models are typically produced over a period of several years, but individual parts
are often released in a new improved version and for compatibility and replacement purposes it can be
important to know the version currently installed.)
Two different formats for the Mfg Code have been used over the years (‘A’ denotes a letter, ‘d’ a date digit
and ‘x’ a digit):
• Older format is AddddddAxx (eg E130710F89)
• Current format is AAddddddxxx (eg MC130311013)
But the meaning of the fields is essentially identical, despite the slight change in order:
• The first letter is the major revision level
• The second letter is nowadays the minor revision level (perhaps other uses in past years)
• The next sequence of 5 or 6 digits encodes the date of manufacture as YYMMDD – 6 digits is the
standard now but prior to 2011, 5 digits was used as in YMMDD.
• The final digits simply indicate which number within the production batch was allocated to that unit, eg
013 might indicate unit 13 out of a batch of eg 200 (or whatever the batch size was on that day)
Thus unit E130710F89 was major revision E, minor revision F, manufactured on 10th July 2013 and unit 89
in the batch.
