Ramp & Soak provides users with the flexibility to slowly bring the Process
Variable (PV) to the desired set point. Ramp & Soak values are specified in
HH.MM format. The Ramp value indicates the time specified to bring the process
variable to Setpoint 1 (SP1). Once set point is reached, the PID takes over and
the Process Variable will be controlled at the desired set point indefinitely. If
Soak is enabled, PID will control the Process Variable at the specified set point
for the duration of Soak time and then will turn off Output 1. To start a new
Ramp/Soak cycle, reset the instrument by pressing
a and then c button.
An active Ramp/Soak will change SP1 one count above the PV and will cause
the most significant digit to blink. The SP1 will be incremented by one count until
it reaches the original SP1. The minimum Ramp time must be at least twice the
time that it will take the PV to reach the Setpoint Value (SV) with OUT 1 fully ON.
