Manual

CR10X Storage and Control Module

The reader is referred to Annex 5, for detailed instructions on how to check the daily program signature,. A change

in program signature requires that METSTAT needs to be reloaded (for the appropriate instructions to this end see

paragraph 2.2).

2.6 Prompt Sheet

The project has prepared a Prompt Sheet, which is intended as memory aid when going into the field to visit the

Automatic Meteorological Stations. This sheet contains: (a) all relevant keyboard commands, (b) the wiring diagram,

while checking and operating the station.

The Prompt Sheet is included at the back of this manual. An additional laminated copy is provided, and can be left

on site in the ENC12/14 protective enclosure.

2.7 Trouble Shooting

Problem 1: Logger is not recording/general failure.

Cause: The majority of general operation failures is due to a corrupted data logger program.

Remedy 1.1: Place a secure version of METSTAT in program location 8 of the Storage Module SM4M. De-acti-

vate security by following the instructions in Box 2. Connect the SM4M to the data logger with the SC12 cable.

Switch power Off/On. The secure version of METSTAT is now automatically loaded into the logger’s system memory,

compiled, and made the active program. Re-activate security by following the instruction given in paragraph 2.2.

If the problems persist, all indicators are pointing towards a hardware problem.

Remedy 1.2: check if all cables are properly connected; check if wiring is according to the wiring schedule pre-

sented in Annex 2; check if power is connected (please note that the keyboard display CR10KD is powered by the

logger, hence, if it works properly the problem is not related to power).

Remedy 1.3: check the grounding. The reader is referred to paragraph 4.5 for detailed instructions on how to

ground the Met Station.

A series of test in the Project office has shown that inadequate grounding can have significant influence on the

measurement values.

Box 4: Transfer Data Prior to Re-loading METSTAT into CR10X

Although re-installing METSTAT does not erase information stored in the logger’s Final Storage Areas, it is

advised to transfer all data to the storage module prior to (re-) loading METSTAT into the CR10X. To this effect,

follow the instructions given in paragraph 2.3.

Problem 2: Data have been lost somewhere in the trajectory between logger and computer, or, have accidentally

been deleted from the database.

Remedy 2: Due to the applied ring configuration of the logger’s RAM, data are not erased from Final Storage

after data dump. Only when the memory is full, old information is written over by new one. Given the expected data

output of METSTAT and the size of the logger’s RAM, data are preserved for about 5 months in Final Storage before

being written over. Consequently, in the unlikely case that data are lost somewhere in the trajectory between Met

Station and computer, or, if data are accidentally deleted from a database, it may still be recovered from the logger’s

RAM.

To down load “old” data from CR10X to SM4M, type in the following CR10KD keyboard instructions (for presentation

purposes given between double quotes):

1 2 ... 16 17 18 19 20 21 22 23 24 25 26 ... 74 75
