Actual  selected  sensor  type  is  displayed  -  symbols 

ni

  for  sensor 

Ni1000/6180ppm  or 

Pt

  for  sensor  Pt1000/3850ppm.  If  setting  of  the 

instrument  does  not  match  the  connected  RTD  probe  type,  displayed 
temperature readings are not correct. It is necessary to set instrument for 
connected probe type from the PC program. The setting is enabled only if 
logging is not started.  

 

Display  refresh  mode  is  indicated.  In  the  FAST  mode  refreshment  is 
fastest with regular  interval approximately 0.7 s. In the dynamic refresh 
mode (DYN.) each 15 s refresh interval of display is doubled to maximum 
5  s  if  measured  values  are  stable.  If  measured  values  change,  refresh 
interval decreases to approximately 0.7 s. This dynamic mode prolongs 
battery life significantly. Select the desired mode by ENTER key. Notice: 
if  battery  voltage  is  low,  the  FAST  mode  is  out  of  operation  to  reduce 
current consumption independently on this selection. 

 

Each  pressing  of  ENTER  key  causes  displaying  information  on  storing 
interval,  actual  logging mode (MODE), memory  occupation  (MEMO  -  in 
automatic logging mode memory occupation in % is displayed, in manual 
mode the number of logged values is displayed) and service information 
on  software  version  (upper  LCD  line)  together  with  instrument 
configuration on the LCD lower line.  
 
 
 
 
 
 

 

Alarm indication and setting 

 

It is possible to set lower and upper limit for each measured quantity. 
Breaking of the limit is indicated by blinking of the appropriate value 
on the display. If a new alarm was indicated (i.e. it was not active in 
the previous measurement), display starts to display the value out of 
limits. If at least one alarm is active, audio indication can be activated, 
if menu AUDI "On" is selected (see setting described above). Alarm 
activation of each value can be disabled by setting lower alarm limit 
of  the  desired  value  up  to  its  maximum.  This  is  indicated  by  OFF 
reading at the position of numeric value. Value of upper limit of the 
same alarm is indifferent. 

 

To set alarms press MENU key, select ALAR from menu items and 
confirm by pressing ENTER key.
