Page 22: Cycle Time
The cycle time is indicated in hours (h) and minutes (min.). With this function, the system can be started at any time during the se- lected temperature profile. For example in case of CDF test, when the system should start at 10 a.m. and the weathering should be determined at 1 to 3 p.m., the cycle time should be set to 7 h and 30 min. -
