•Remove the module from the frame and plug it back again. Then perform  “Calibration 
check”  (see the preceding page) to verify the new calibration.
3.4.2 Temperature calibration
NOTE: For the temperature calibration, separate, accurate test plugs (25 °C and 45 °C) are 
needed. A test set of two plugs is available from GE Healthcare, order code 884515-HEL. 
A Dual temperature adapter cable, order code 2016998-001 is also required...
