Cycle of automatic calibration proceeds as follows:

 

 

-

  balance software detects necessity of calibration and signalizes it by marker of 

Celsius degree or by black marker

 

 

 

-

 from this moment time of 5 minutes is counted in which weighings can be 

performed

 

-

  when this time elapses display indicates CAL_30 message and starts count 

down  30..29..28 do 0 (indicated value is the counter)

 

 

 

 

-

  user has 30 seconds to make a decision: 

 

ƒ

  if calibration is to be performed, does not take any actions

 

ƒ

  if one wants to finish measurements presses 

TARE

 key, after its pressing 

balance returns to weighing showing previous result of weighing (possibility 
of finishing series of measurements) in 5 minutes balance will indicate 
CAL_30 message again

 

 

-

  process of calibration can be postponed frequently, but fact that long postponing 

of calibration can be cause of bigger error during weighing should be noticed. 
These errors are effect of changes of temperatures and as consequence 
changes of balance sensitivity.

 

 
Automatic system includes 3 possibilities: 

 

-

 

calibration with regard to changes of temperature

 

balance is provided with precise system of controlling temperature 
changes, temperature of calibration is registered every time, next is started 
if temperature of surrounding changes 0,8

o

C  

 

 

 

-

 

calibration with regard to passage of time

 

user can declare 4 spaces of time that makes criterion for calibration, 
following option are accessible: calibration every 1 - 12 hours.
