Initial Hold Time (min) – This is the time in minutes the initial
temperature is maintained. The initial hold time can be programmed from
0.0 to 999.9 minutes.
Ramp Rate (°C/min) – This is the rate programmed in °C/min the sample
preheat temperature will increase after the initial hold time has expired to
the desired final temperature set point. The temperature ramp can be
programmed to the final temperature set point 1°C/min increments.
Final Temperature (°C) – This is the ending temperature programmed in
°C. The temperature can be programmed from 35°C to the final sample
preheat temperature in 1°C increments.
Final Hold Time (min) – The final hold time is not a value to be entered
by the User. The final hold time is the calculated difference between the
Sample Preheat Time taken from the sum of the initial time and the
ramping time needed to achieve the final temperature.
For Example: Total Sample Preheat Time = 10 minutes
Initial Temperature = 30°C
Initial Hold Time = 2 minutes
Ramp Rate = 5°C/min per minute
Final Temperature = 60°C
Final Hold time = 2 minutes.
Explanation: Since it takes 6 minutes to ramp from 30°C to 60°C at a rate
of 5°C/min per minute. The final hold time is calculated to be 2 minutes.
10 minutes – (2 minutes + 6 minutes) = 2 minutes
