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.
Entering a New Program
To program the Calibrator, use the keys on the front panel to change values on the
Calibrator’s program editing screen. Instructions for entering each step of a new program
are included below.
1. Ensure that the units, limits, and control parameters have been set to the desired
values.
2. The program is entered from the Program Menu. From the Main Menu (press
PREVIOUS until the Main Menu appears), press Menu [F6] | Program [F4].
