Program configuration
Configuration elements of a program can roughly be classified into “segments” and the “repeat
command”. “Segments” comprise of those defined with “ramp time”, “ramp level”, “soak time” and
“wait” and a special segment that indicates the end of a program (called “end segment”). “Repeat
command” is defined with “repeat start segment” and “number of repeats”.
Description
Contents of a segment
* Configuration elements of a segment
A program consists of segments and patterns of each
segment is defined by setting three basic elements
below:
1. Ramp level
：
Target temperature setting
2. Ramp time
：
Time necessary to attain the ramp level
3. Soak time
：
Ramp level hold time
* Constant rate gradient operation
＜
See Figure 1
＞
1. In the ramp interval (A), the constant rate gradient
operation specified with a ramp level and a ramp
time is carried out towards the temperature set with
a ramp level.
2. In the soak interval (B), the temperature set with a
ramp level is held for the time period set with a soak
time.
→ Setting is made in the following order.
（
See P.38
and following pages “How to input a program”.

* When constant rate gradient operation is not
conducted
＜
See Figure 2
＞
1. Set
as the ramp time if you want to reach
the ramp level in the ramp interval as quickly as
possible.
* When linking gradient operation <See Figure 3>
1. When carrying out different constant rate gradient
operations consecutively, set the soak time for the
first segment (segment A) to “0”. (There is no soak
intervals.)
* Other segment-related elements
1. Wait function (See the wait input example on the right)
When the measured temperature does not attain or is
different from the target temperature due to loads or
externa disturbances, this function does not move the
ramp interval to the next until the target temperature is
attained and, for the soak intervals, suspends soak time
count until the target temperature is attained. Set
ON/OFF after entering a soak time.
2.
End segment
Call for and enter
as the ramp time of the
last segment when you want to complete inputting a
new program. This procedure is not necessary
when you have input a program up to the 5
th
segment.
