Installation, Operation and Maintainance of Automatic Meteorological Stations

CR10X Storage and Control Module

Upon toggling the PS12-LA Power Supply switch to “ON”, the program stored in location 8 of the SM4M storage

module (in this case METSTAT) is automatically loaded into the CR10X, and subsequently made the active program.

Make sure that the installation of all hardware components is completed before powering on the datalogger.

Box 2: Loading METSTAT into CR10X Storage and Control Module

(it is assumed that METSTAT is stored in program location 8 of the SM4M)

Option 1: Automatically

-1: connect SM4M to CR10X;

-2: switch power Off/On by toggling the switch on the PS12-LA Power Supply;

-3: METSTAT is now automatically loaded and made the active program.

Option 2: Manually Using the CR10KD Keyboard Display

Connect the CR10KD and SM4M to the CR10X and type in the following keyboard instructions (for presenta-

tion purposes given between double quotes):

“*D” (to activate Star D Mode; the display shows 13:00)

“71” (code for SM4M)

“A” (keyboard equivalent for ENTER; the display shows 71:00)

“28” (“2” stands for loading a program, “8” stands for program location 8)

“A” (keyboard equivalent to ENTER; METSTAT is now loaded and activated)

METSTAT is a datalogger program specifically created by the Project for the selected sensor configuration, and

adapted to the required measurement schedule in the Nile Basin. It is written in the proprietary Campbell Scientific

programming language. The reader is referred to Annex 3 for more information on the METSTAT program.

To set the CR10X system clock, type in the following keyboard commands (given between double quotes for pres-

entation purposes):

“*5” (to activate Star Five Mode; the display shows the current time in HH:MM:SS)

“A” (keyboard equivalent to ENTER)

“YYYY” (enter Year)

“A” (keyboard equivalent to ENTER)

“DDDD” (enter Julian Day; See Prompt Sheet to transfer calendar days to Julian days)

“A” (keyboard equivalent to ENTER)

“HHMM” (hour and minute)

“A” (keyboard equivalent to ENTER)

The next step in the installation process is assigning a datalogger-ID to the station. This ID obviously serves to

separate data from different sources. This is needed when a single storage module is used for transferring meas-

urements from several stations to one office PC. METSTAT does not contain an automatic routine for this purpose.

Instead, the user has to define the ID manually during installation.

To assign the ID, type in the following keyboard commands (given between double quotes for presentation pur-

poses):

“*D” (activates D mode)

“8” (to go to command option 8)

“A” (keyboard equivalent of ENTER)

“xxx” (enter datalogger ID, this should be an integer between 1 and 12 or 14 and 254)

“A” (keyboard equivalent to ENTER)

“*0” (to activate the program, begin logging and re-enable security)
