4. Define the cycle time: "Cycle time" parameter field.
Note
Specifying the cycle time
The cycle time always extends from the start time of one AutoCal/AutoVal sequence to
the start time of the next. The smallest cycle time is 1 hour.
If the set cycle time is less than the actual expiration time required, then:
• The next AutoCal/AutoVal is held back until the end of the previous process.
• The "Calibration" operating mode is not exited.
This means you have to set a cycle time that is greater than the expiration time of an
AutoCal/AutoVal.
The cycle time commences immediately after the first execution of an AutoCal/AutoVal.
If the function is triggered manually between the cycles, the cycle is retained. Missed
cycles are not made up for later. The cycle starts at the next cycle time.
5. Check the time remaining until the next cycle start: "Remaining time" display field.
The remaining time is the time between the first execution of an AutoCal/AutoVal and the
cycle time. The device adjusts the remaining time following a successful
AutoCal/AutoVal.
If the first execution has not been carried out yet, the device indicates the remaining time
up to the start of the function.
6. Starting AutoCal/AutoVal manually: "Trigger AutoCal n once" or "Trigger AutoVal n once"
parameter field ("n" stands for the selected AutoCal/AutoVal 1 or 2).
Follow the instructions on the display. Triggering of the process has no influence on the
time cycle. The cycle time continues to run.
