Programming of the address for the communication network (

SET ID ADR

) (only for vers. with serial output)

After the confirm with the 

A

 key of the previous value, the message 

ID aDR

 will appear on

F

 display; to set the value 

that will identify the instrument when it will be connected in a EIA485 communication network, proceed with the 
modality, already described. The settable values are from 1 to 247. To confirm, press the 

A

 key. 

Programming of the baud rate (

SET BDR

) (only for vers. with serial output)

The following setting is the baud rate. The message

SET

appears on

G

display, the message

SET BDR

on the first

two parts of

F

display to indicate the programming of the baud rate displayed on the third part (L3) o

f

 the

F

display. To

modify the value set, it’s necessary to use the

C

key to decrease and

B

to increase the rate. The values settable are:

-

19.2

 => 19200 

baud 

-

9.60

 => 9600 

baud 

-

4.80

 => 4800 

baud 

-

2.40

 => 2400 

baud 

Press 

A

 to confirm the value displayed. 

Programming of the serial parameters (only for vers. with serial output)

On

G

 display will appear the message 

SET

. The following message will appear on 

F

 display using the 

B

 and 

C

 keys. 

To confirm press the 

A

Programming of the Password (

SET PAS

)

The instrument is supplied without password. When a password (from 0002 to 9999) is set, using the 

B

 (to increase), 

C

 (to decrease) and 

A

 (to confirm) keys, only who know this value can to enter in the setup. The password, in fact, is 

required all the time that someone try to enter in the setup (pressing the 

A

 and 

B

 key at the same time). If the 

password is wrong, the message 

PASS ERR

 will appear on 

F

 display and the instrument go back to the measures 

visualization. To input the password, when required by the instrument, at the enter of the setup, use the 

A

,

B

 and 

C

keys as the same way done previously. 

The menu is cyclic. After the last setting, the instrument go back to the first page of Setup (SETUP). It’s always 
possible to come back to measures visualization mode pressing at the same time the 

A

 and 

C

 keys.

PEAK VALUES AND ENERGY COUNTERS RESET (

RESET

)

From the measures visualization mode, pressing the 

A

 and 

C

 keys simultaneously the message 

SETUP

 will appear 

on

F

 display, press the key 

C

 until the message 

RESET

 appears on the same display. To accede to the menu, press 

the

A

 key. Now it’s possible to select the enabling of cancellation type, by pressing the 

C

 key, according with following 

types: 

RESET PEA

: all maximum value will be delete. 

RESET AVG

: all average and average maximum value (maximum demand) will be delete. 

RESET EN

: with 

NORMAL

 as energy mode (

EN

) the total energy counters will be delete, with 

TOT  PAR

 the 

partial energy counters will be delete (as when the digital input is closed) and with 

TB1 TB2

 the band 

counters will be delete. 

RESET ALL

:  to delete average maximum values and energy counters.
