KEYBOARD FUNCTIONS

L and M keys - Used to scroll display pages, to select among possible choices, and to modify settings (increment-decrement).
key – Used to rotate through sub-pages, to confirm a choice, to switch between viewing modes.
VIEWING OF MEASUREMENTS
– The L and M keys allow to scroll the pages of viewed measurements one by one. The page being viewed is written in the title bar.
– Some of the readings may not be shown, depending on the programming and the wiring of the device (for instance, if programmed-wired for a three-phase
without neutral system, L-N voltage page is not shown).
– For every page, the key allows to rotate through several sub-pages (for instance, to show the highest/lowest peak for the selected readings).
– The sub-page viewed is indicated in the status bar on the bottom of the display by one of the following icons:
• IMP = Imported energy – Power taken from the energy supplier (positive sign)
• EXP = Exported energy – Power given to the energy supplier (negative sign)
• TOT = Total energy – Total energy meter, not clearable by user
• PAR = Partial energy – Partial energy meter, clearable by the user by means of commands menu
• IN = Instantaneous value – Actual instantaneous value of the reading, shown by default every time the page is changed.
• HI = Highest peak – Highest peak of the instantaneous value of the relative reading. The HIGH values are stored and kept even when auxiliary power is
removed. They can be cleared using the dedicated command (see commands menu).
• LO = Lowest peak – Lowest value of the reading, stored from the time the DME power-on. It is cleared using the same command used for HI values.
• AV = Average value – Time-integrated value of the reading. Allows showing measurements with slow variations. See integration menu in setup chapter.
• MD = Maximum Demand – Maximum peak of the integrated value. Stored in non-volatile memory, it is clearable with dedicated command.
• GR = Bar graphs – Shows the measurements in bar graphs.
Indications on the main page
Example of display page with numeric indication
– The user can define to which page and sub-page the display must return to after a period of time has elapsed with no keystroke.
– If needed, it is possible to set the multimeter so that the display will always remain in the position at which it has been left.
– To set these functions see menu M02 – Utility.
PROGRAMMED CT VIEWING
– The CT ratio currently programmed is viewed on all the pages of the energy meters, in the lower section of the status bar.
– The reading gives the value of the primary and secondary values programmed in parameter P1.01 and P1.02.
– The reason for this is to highlight on the display eventual tampering of programming that can alter the energy count.
