KEYBOARD FUNCTIONS

MENU key - Used to enter or exit from viewing and setting menus.
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.

MEASUREMENT VIEWING

– 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:
• 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 DMG is powered-on. It is resetted 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 and it is resettable with dedicated command.
• GR = Graphic bars - Shows the measurements with graphic bars.
Example of display page with numeric indication
1 - Unit of measure
2 - Measurement
3 - Title bar
4 - Phase indication
5 - Sub-page indication
Example of display page with bar-graphs
1 - Unit of measure

4 - HI-LO markers
– The user can define to which page and sub-page the display must return to after a period of time has elapsed without any keystroke.
– If needed, it is possible to set the multimeter so that the display will remain always in the position in which it has been left.
– To set these functions see menu M02 – Utility.
