DISPLAY INDICATIONS

I422 GB I 10 17 31100212

DISPLAYING MEASUREMENTS

– The



and



buttons allow the measurement display pages to be scrolled one at a time. The current page can be recognized through the unit of measurement shown in the top part of the display.

– Some measurements may not be displayed, depending on the programming and the connection for the device (for example, if programmed for a system without neutral, the measurements relating to neutral are

not displayed).

– For every page, the button permits access to sub-pages (for example, to display the maximum and minimum values recorded for the selected measurement).

– The sub-page displayed currently is indicated at the bottom right by one of the following icons:

•

IN = Instantaneous value – Current instantaneous value of the measurement, displayed by default every time the page is changed.

•

HI = Maximum instantaneous value – Highest value measured by the multimeter for the corresponding measurement. HIGH values are stored and preserved even in the absence of a power supply. They can be

reset through a dedicated command (see commands menu).

•

LO = Minimum instantaneous value – Lowest value measured by the multimeter from the moment voltage is applied. It is reset with the same command used for the HI values.

•

AV = Average value – Time-integrated (average) value of measurement. Permits display of a measurement with slow variations. See Integration menu.

•

MD = Maximum Demand – Peak integrated value (max demand). Remains stored in non-volatile memory and can be reset with a dedicated command.

– The user can choose the page and sub-page that the display returns to automatically after a certain time has elapsed without the buttons being pressed.

– It is also possible to program the multimeter so that the display always remains that which was last selected.

– For the set-up of these functions, see the P02 – Utility menu.

HARMONIC ANALYSIS INDICATION

– The DMG100-110 features harmonic phase analysis up to the 15th order for the following measurements:

•

phase-to-phase voltages

•

phase-to-neutral voltages

•

currents

– To activate harmonic analysis, parameter P02.12 must = THD/HAR.

– With P02.12 = THD, only the THD of the above measurements is displayed.

ENERGY METER INDICATION

– There are five dedicated pages for energy meters.

•

Imported and exported active energy

•

Inductive or capacitive reactive energy

•

Apparent energy.

– Each page displays the total and partial value (can be reset from commands menu).

– If the unit of measurement is displayed continuously, it means that the meter is for imported energy (positive). Display of exported (negative) energies can be enabled as well by setting parameter P02.09 to ON.

These energies are highlighted by the flashing of the unit of measurement, and are displayed after the imported energies by pressing



– If display of energy by individual phase is enabled (P02.10=ON), three independent additional pages, one per phase, will be displayed for each power, including total and partial energy.

HOUR COUNTER INDICATION

– If the hour counter is enabled (see menu P05), the DMG100-110 displays the hour counter page, with the format indicated in the figure:

LIMIT THRESHOLD STATUS INDICATION (LIMX)

– If the limit thresholds are enabled (see menu P08), the DMG100-110 displays the page, with the corresponding status and the format indicated in the figure:

– With limit threshold activated, the word ON flashes, while if it is deactivated the word OFF is constant. If no limit threshold is programmed, dashes are displayed.

Imported active energy Exported active energy

I422 GB I 10 17 31100212

ALARM INDICATION

– If alarms are enabled (see menu P09), the DMG100-110 displays the page, with the corresponding status and the format indicated in the figure:

– With Alarm activated, the word ON flashes with the triangle symbol, while if it is not activated the word OFF is constant.

– If no alarm is programmed, dashes are displayed. After about 3 s, the scrolling text of the alarm programmed in parameter P09.n.05 appears.

– With several alarms active, the text of the corresponding alarm alternates on the display.

– Dedicated parameter P02.14 for the utility menu can be used to make the display backlighting flash in the event of an alarm to highlight the presence of the fault.

– The alarm reset method depends on parameter P09.n.03. This determines whether it can be automatic, on the disappearance of the alarm conditions, or requires manual intervention through the commands menu

(C.07).
