D.2.1.5 “Device parameters” panel 

D.2.1.5.1 The  “Device parameters” panel contains  information about static parameters, which 

are  not  used  in  the  measurements  process,  and  dynamic  parameters,  which  define  measurement 
characteristics of the device, and also general information about the device operation. 

D.2.1.5.2 Static parameters: 
-

 

Device address; 

-

 

Device; 

-

 

Device code; 

-

 

Firmware version; 

-

 

Configuration date; 

-

 

Assembly date; 

-

 

Device date/time; 

-

 

Volume level; 

-

 

Current device language; 

-

 

Factory number: 

Parameter  “Configuration  date”  is  a  variable;  it  is  automatically  changed  when  the  “Set 

parameters” button is pressed. 

Parameter “device address” represents the net address of the device. 
D.2.1.5.3 Dynamic parameters 
Each device has its own set of dynamic parameters. Some parameters can possess the value of 

0 or 1; some parameters can possess the value in the exponential form, for example 2.3E-003 (0.0023). 
Some parameters are “read only”, for example “Running hours”. 

Correction of the parameters is carried out as follows: 
-

 

double click on the line of the parameter to be corrected; 

-

 

in the column “New value” input new parameter value; 

-

 

press “ENTER” or click on any other line; 

-

 

if necessary, correct other parameters; 

-

 

press the button “Set parameters F2”; 

-

 

check  correctness  of  the  writing  –  new  parameter  values  will  be  displayed  in  the  column 

“Parameter point” after a while. 

ATTENTION!

  DECIMAL  POINT  (SEPARATOR  BETWEEN  INTEGER  PART  OF  THE 

NUMBER  AND  THE  FRACTION)  IS  USALLY  A  DOT  (.).  HOWEVER  YOUR  OPERATION 
SYSTEM  CAN  BE  SET  TO  USE  COMMA  (,)  INSTEAD.  BE  CAREFUL  WHEN  YOU  INPUT 
NUMBERS. 

Sets of values or ranges of values of parameters are indicated in the operational documentation 

for each device. 

D.2.1.5.4 Buttons on the “Device parameters” panel 
In the upper part of the “Device parameters” panel the following buttons are located: 
-

 

“DEVICE DATE/TIME” – this button is activated for devices that has or emulates built-in 

clocks; 

-

 

“SET DEVICE LANGUAGE OF THE INTERFACE” – this button is activated for devices 

with multilanguage interface, it allows setting the active language of the device; 

-

 

“SET  VOLUME  LEVEL”  –  this  button  is  activated  for  devices  equipped  with  adjustable 

signaling features, it allows to set the desired volume and, if necessary, to test it; 

-

 

“SET  ADDRESS”  –  in  the  broadcast  mode  this  button  allows  to  set  the  net  address,  for 

setting the address press the button “Set address”, then in the window that will appear input the new 
address  –  three  dot  separated  groups of  digits  (3  digits  in  each  group).  The  range  of  values  in  each 
group – from 002 to 254. After completion the input click “Ok”. The new address will be written into 
the non-volatile memory of the device. At the same time parameter “date of correction of parameters” 
is automatically set to current date;
