SOFTWARE FUNCTIONS
PASSWORD: Numeric code of max. 3 digits;
• 2 protection levels of the programming data.
• 1st level: Password "0", no protection
• 2nd level: Password from 1 to 499, all data are protected.
MEASUREMENT SELECTION: see the relevant table.
TRANSFORMER RATIO:
For CT up to 30000A, For VT up to 600kV.
SCALING FACTOR
Operating mode:
• Electrical scale: compression/expansion of the input scale to be
connected to up to 4 analogue outputs and up to 4 alarm outputs.
• Electrical range: Programmable within the whole measuring range.
DIGITAL FILTER:
• Filter operating range: 0 to 99.9% of the input electrical scale
• Filtering coefficient: 1 to 255
• Filter action: alarms, analogue and serial outputs (fundamental
variables: V, A, W and their derived ones).
EVENT LOGGING: Only with the RS232 + RTC module. The max./min.
values of the selected variables and the alarm status are stored with
reference to date (dd:mm:yy) and time (hh:mm:ss). Max. capacity: 480
events.
PAGE VARIABLES: 4 variables per page; up to 27 variable pages one
of which is completely programmable.
