Ramp Time
“Ramp Time” is the default amount of time defined by the user for the instrument to reach the temperature or pressure.
The instrument default ramp time is ten (10) minutes. The Discover System will achieve the set temperature as fast as
possible. The ramp time is a maximum amount of time that power will be applied before switching to the hold time. When
creating a new method, the ramp time can be changed from the default ramp time programmed in the “User Profiles.”
1. Use the “+/-” keys to highlight “Ramp Time.”
2. Press the ENTER key.
3. Use the ARROW keys to toggle between hours, minutes and seconds. Use the “+/-” keys to increase and decrease
the hold time (0 - 99 hours, 59 minutes, 59 seconds).
4. Press the ENTER key to accept the default ramp time.
Temperature
“Temperature” is the user defined control temperature. The default temperature is 125°C. When creating a new method,
the temperature can be changed from the default temperature programmed in the “User Profiles.”
