MaxTime

The max time is the maximum time in seconds including the dwell time that the Calibrator can spend on one step of the program. After the max time elapses, the Calibrator will automatically proceed to the next set-point in the program, even if the current set-point has not been achieved. Thus, the max time selection limits the amount of time that the Calibrator can spend on any one set-point. Typically the max time should be set to a value greater than the dwell time. If the max time is set to zero, the Calibrator will attempt to achieve the set-point indefinitely (i.e. the max time function is disabled).

Mode of Entry

If the upscale portion of the desired pressure step sequence and the downscale portion of the sequence both have the same highest and lowest set-points and consist of evenly spaced steps, the <Auto> option can be used to automatically generate the program. However, if any part of the sequence includes unevenly spaced steps, or the starting and ending set-points are not the same, each step must be programmed individually. In the example given at the beginning of the section Menu Program – Storing a Sequence in Memory, each step must be programmed individually since the starting set-point is 30 psi and the ending set-point is 20 psi.

Detailed instructions for entering these items are given in the sections that follow.
