4.14 PERFORMING ADJUSTMENTS
In general, a comparative measurement should be made. Refer to the chapter, "Com-
parative Measurements and Adjustments" in the operating instructions.
An adjustment routine can be initiated for each adjustable regulation circuit by using
the -cal- key.
4.14.1 TEMPERATURE ADJUSTMENT INCUBATION MODE
Comparative meas-
urement: Incubation temperature
Perform the comparative measurement at the user's normal operating temperature,
e.g., 37.0°C. Make sure the unit has adequate time to reach equilibrium before taking a
reading:
- For cold units: No sooner than 5 hours after the temperature has reached
equilibrium or the end of a complete -auto-start- procedure.
- For units at oper-
ating temp.: No sooner than 45 min. after probe placement.
Comparative measurement proce-

Place the probe in the center of the sample chamber, 15 mm above the insert tray.
Open the doors as briefly as possible for this step.
Allow the unit to reach equilibrium or the -auto-start- routine to finish.
Read the probe value and compare it with the displayed value.
