8.- Introducing how to programm the instrument______________________________
The MAG983 instruments do not have programming keypad accesible to the end user. To modify the configuration
of the instrument, access the internal pins and configure the contacts indicated on «figure 1». These contacts
will allow the activation of the required programming codes.
Example .- To activate code «65 2E» (activation of decimal point at position XXXXX.X) close one after the other
contacts «6», «5», «2» and «E»
Contact 6 Number «6» appears on display 6
Contact 5 Number «5» appears on display 65 1
Together with code «65» appears also the number «1» indicating that code «65»
already has a value of «1», this means, configuration without decimal point
Contact 2 Number «2» replaces number «1» 65 2
Contact E The instrument activates the decimal point XXXX . XX
Note .- the programming codes «1», «2» and «3», are composed of 1 digit only. When closing contact «3» the
display will show a 5 digits number, which is the actual value of the «Scale Factor» (by default its value is
«1.0000»). To modify each one of these 5 digits, close contacts «1» to «5» and once the desired value is on the
display close «E» to validate.

ATTENTION - Límit on the Internal Counter
The MAG983 instrument works with a 23 bits
internal counter (maximum 8.388.608 impulsos can
be counted). If this value is exceeded, the negative
led sign is activated and the display will work in
SUBSTRACT mode. Do a «RESET» of the display in
order to recove functionality. Memory «AL2» can be also
programmed to activate a «RESET» when its value is
reached (see code «56 5E»).
