Press  DISPLAY  key  to  display  pressure  tendency  (hPa),  which  is 
the difference  between  actual  pressure  and  pressure  before  3  hours. 
If the instrument is not switched ON at least 3 hours, pressure tendency 
is not available yet and symbol „--„ is display. 

 

 
 
 
 

 

Function HOLD (storing of actual measured values) and 
minimum a maximum memory  

 

Press  HOLD  key  in  the  default  mode  (displaying  of  actual  measured  value)  to  store  actual 
measured values to internal memory (indicated by short beep). Anytime it is possible to display 
stored  values  from  MENU  (see  below).  Each  pressing  of  the  HOLD  key  in  the  default  mode 
causes values stored in HOLD memory are replaced with actual ones.  
 

Switched  ON  instrument  permanently  updates  minimum  and  maximum 
memory  of  each  measured  values.  Press  MIN  key  (resp.  MAX  key)  in 
the  default  mode  to  display  minimum  (resp.  maximum)  reading.  These 
minimum  and  maximum  readings  are  indicated  by  MIN  (MAX)  symbols 
on  the  LCD.  Press  DISPLAY  key  to  display  minimum  (resp.  maximum) 
value of other values. Pressing MIN (MAX) or MENU key again to return 
to default mode. Minimum and maximum memory is cleared from menu 
after confirmation selection CLR (see below). Values in HOLD, MIN and 
MAX memories remain stored even after instrument is switched OFF.
