Operation 

Turn device on via 

 key. 

After segment test 

 

 

the device displays some information on its configuration: 

  if cell correction scale was changed (cell correction scale unequal 1.000) 

  

(see chapter 11 Automatic adjustment/calibration of cell correction) 

   if zero point or slope correction is active 

 

(see chapter 10 Adjustment of temperature input) 

After that the device is ready for measuring.
