CANCELLING OF THE PEAK VALUES AND ENERGY METERS (

From the measures visualisation mode, keep the 

A

 key pressed until the message 

 appears on the 

C

 display; 

then press the 

B

 key until the message 

 appears on the 

C

 display; access to the reset menu by pressing the 

A

 

key. By pressing the same key we can now select the cancellation type that we wish to activate. 
Here below the different types: 

 

 

cancellation of the instantaneous values only 

 

cancellation of the average values in the 15’ only 

 

cancellation of the energy meters 

 

cancellation of the energy meters, average and the instantaneous values. 

 

To activate the selected cancellation mode, press the 

B

 key to change the 

C

 

display’s indication from 

 to 

Confirm to activate the cancellation, by pressing the 

A

 key; the indication in the display 

C

 will pass from

Without pressing any key, wait until the instrument returns to the measures visualisation mode. 

 

PROGRAMMING THE DIGITAL OUTPUT (

)

 (only

 

for EMM-µD3h-p)

 

In  the  menu 

  and 

 

it’s possible to program the function of all digital outputs. In these menus are 

available the following modality: 

 and 

 (alarm). 

In 

 mode the digital output DO1 will emit pulses proportional to the active energy counted while the digital output 

DO2 will emit pulses proportional to the reactive energy counted. The proportionality will depend from the 

 set in 

the 

 and the duration of the impulse is set in the 

 voice of the 

In 

  mode  there  are  three  settings 

  for  the  three-phase  connection  and 

 for the single phase connection. With 

 the digital output works as alarm verifying that the (average) 

three-phase  value 

doesn’t exceed the thresholds set (

 and 

). With 

 and 

 

the  digital  output  works  as  alarm  verifying  that  the  maximum  value  of  the  single  phase 

doesn’t  exceed  the  maximum 

threshold set (

) and that the minimum value of the single phase is below the minimum threshold set. With 

 

it’s possible to activate the digital output after a delay expressed in seconds. 

If only 

 

threshold is set, alarm act as “maximum value” function; If only 

 threshold is set, alarm act as 

“minimum value” function; if both thresholds are set, alarm works as “BAND” function.
