Operation of the device 

 

 

Switching ON and OFF the device 

 

Connect  external  probe  to  the  instrument  before  switching  ON. 
The probe  is  calibrated  with  the  instrument  and  it  is  not  possible  to 
replace  it  with  another  probe  from  another  instrument.  Switch  ON 
the instrument  by  pressing  ON/OFF  key.  After  switching  ON 
the instrument all symbols on the LCD are displayed. If the ON/OFF key 
is  being  held  pressed,  all  LCD  symbols  are  displayed  till  the  key  is 
released. 

 

In  usual  operation  instrument  then  starts  the  measurement  mode  and 
actual  measured  values  are  displayed.  When  instrument  is  ON  do  not 
disconnect the probe to avoid storing of improper values to the min/max 
memory. 

 

 
 

 

Displaying of actual measured values 

 

In this mode is instrument  any time after switching ON. It is possible to enter this mode from 
other modes by pressing or by repeating pressing of MENU key. If the probe is not connected 
properly or temperature is out of the range symbol “--“ is displayed. 

 

 
Temperature 

is  displayed on  the  upper  LCD  line  (°C EXT)  and  relative 

humidity in %RH is displayed on the lower LCD line. Those readings are 
from the external probe. 
 

 

 

 

Press  DISPLAY  key  to  display  other  readings  -  ambient  temperature 
from internal sensor (°C INT) and the dew-point temperature calculated 
from external probe values (symbol DP). 

 

 

 
 
 

Press DISPLAY key to display other readings - atmospheric pressure in 
hPA on upper line and dew point temperature on lower line (°C DP).
