2. INPUTTING, EDITION AND DELETING PROGRAMS

2.1 Program Composition

A program is a combination of segments and repeat commands, in which ramp time,

ramp level, repeat frequency, end segment and other parameters should be preset.

[Segment]

Fig 2.1 shows the concept of a segment. Temperature and time patterns of a segment

are determined by the 3 basic parameters below.

Ramp level : Desired temperature

Ramp time : Time required to achieve the preset ramp level

Soak time : Time to hold the ramp level

Fig. 2.1: Concept of A Segment

In Section (

①

of Fig. 2.1~ temperature varies at a fixed gradient rate toward the

desired temperature set as the ramp level. After reaching the ramp level, temperature

is kept in Section

②

of Fig 2.1 for the time preset as the soak time. These sections of

①

and

②

compose a segment.

If you want to vary the temperature in Section

①

on a step (for full-power increase or

decrease), instead of a faced gradient rate, set for the ramp time. Fig. 2.2

shows the pattern of a step variation of the ramp time.
