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. 

Functions and settings available from menu 

Press MENU key to enter mode of viewing menu items one by one. Press arrow keys up and 
down  to  list  all  menu  items.  Press  MENU  key  again  to  return  to  default  mode  (displaying  of 
actual measured values). 

Pressing  the  ENTER  key  enables  to  enter  the  mode  of  setting  alarm 
limits for all quantities (see below).  

This  item  indicates  if  audio  signaling  of  alarm  indication  is  switched  on 
(On) or switched off (OFF). Press ENTER key to change actual setting. 
Notice: if the battery voltage is low, audio indication is out of operation to 
reduce current consumption independently on this selection.
