heating-up, cooling-down and constant temperature curves automatically. The degree of the smooth is relevant with
the system’s lag time t (t=d+CtI) ; the longer of the lag time, the curve will more smooth. On the opposite the smooth
function will be weaker. Generally the shorter of the process lag time (such as temperature inertia), the better of the
program control on effect. By the way of the curve fitting to deal with the program curves, will avoid overshoot. Note:
The characteristic of the curve fitting will force the program control to generate fixed negative deviation during the
linear heating-up and fixed positive deviation during the linear cooling-down, the deviation is direct proportional to the
lag time and the speed of heating-up (cooling-down). This phenomenon is normal.
5. Programming and operation (Fo r AI -526P only)
5.1 Ramp Mode(PAF : B=0)
Programming of instrument has uniform format of temperature-time-temperature, which means temperature “A”(SP 1),
passed Time “A”(t01), then reached Temperature “B”(SP 2). The unit of temperature set is ℃ and the unit of time set
is minute. The following example includes 5 steps, which is linear temperature heating up, constant temperature,
linear temperature cooling down, jump cycling, ready, Hold..
StEP1: SP 1=100 , t 1=30.0 Start linear temperature heating up from 100℃ , and the time needed 30 minutes to reach
SP 2(400 degree).
