parameters error
The setting parameters read by the EEPROM aren't correct.
The device operates with the default parameters.
There could be error in the calculated measures.
The user can’t do the setting.
It is necessary to return the unit to the manufacturer.

EPROM error
Only in the testing phase you can see if the EEPROM doesn’t operates correctly.
Is necessary to contact the manufacturer.
Pressing the button the visual alarm can temporarily be cancelled, and the readings can be shown to verify the causes
of the alarms.

On Cosvalue indication, if the decimal point on last digit (from left) is flashing, this is because the system working as
Generator or the sense of current is inverted (verify correct CT connection or modify parameter .).
b) Press button to scroll on available measurements indicated by the related LED.
c) If a kis on the value must be multiplied x1000, instead If a Mis on the value must be multiplied x1000000.
d) Press both buttons to scroll measure automatically every 3s, press button for stop scroll.
e) While viewing one of these measures: V- A - Cos- W- VAr - VA - %THDV - %THDI if press button for 1s, all
displays and shows the average value measured.
f) While viewing one of these measures: V- A- %THDV - %THDI - TEMP if press  both buttons for 1s, flashes
the relative Led and display shows the maximum value measured.
g) While select Wh measure, the display shows the value for each Phases if .  set in Three-Phase mode or one Phase if
.  set in Single-Phase mode, press it shows the total Wh for 5s.
Press both buttons for 15s to reset all Wh values.
h) While select VArh measure, the display shows the value for each Phases if .  set in Three-Phase mode or one Phase
if .  set in Single-Phase mode, press it shows the total VArh for 5s.
Press both buttons for 15s to reset all VArh values.
i) Only if .  set in Three-Phase mode, while select Vmeasure, the display shows the value  for each Phase, press
it shows the phase voltages.
Press for more than 5s to switch from  to  and set this as default measure value and vice versa.
l) While select TEMP measure, the display shows the current working temperature, press and hold it shows the total
device worked hours.
5.1 MEASURE DETAILS:
MAX VALUE:
The data recording happens every 2 seconds, then after 32
seconds, the micro calculates the average of the 16 different
recording and, if above the stored max value, this goes to
overwrite it and becomes effectively the new max value.
This is to avoid that a single abnormal pike can false the real
situation recording an extraordinary and occasional max value.
For the max Temperature the data is related to the single
reading not to the average.
AVERAGE VALUE:
The data capture occurs every 2 seconds, for example if
.=10 the average value is calculated on 20 seconds.
After power on, during the first 15 minutes, the recording of the max values is disabled.
