Ramping
[F1 RS S 3]
Set the time increment to 3 seconds (must be a positive integer).
[F1 RT S 10]
Set the temperature increment to 0.1 ºC (a positive integer, units are
hundredths of a degree).
[F1 TL +] Ramp
the sample and reference identically (TC 225 dual
controller only).
[F1 TL -] Ramp
the sample and reference separately (TC 225 dual
controller only).
The ramp rate (ºC/min) is calculated as (RT / 100) / (RS / 60). Ramp rates corresponding to selected RS and RT
pairs are given in the table below.

Note: For the higher ramp settings, the observed rate may be lower than that calculated from RT and RS or it
may be nonlinear over part of the temperature range because the maximum possible rate of heating or cooling
is limited (and dependent on the temperature).
To Ramp the temperature:
1. equilibrate at the starting temperature,
2. set the time (RS) and temperature (RT) increments,
3. set a new target temperature.
The new target may be above or below the current temperature and, as soon as it is set, the ramp will begin,
up or down, to that new target.
After reaching the target the controller will hold at that temperature. At any time RS and RT may be reset and
a new ramp initiated by setting another target temperature.
Once you are done, terminate ramping by resetting both RS and RT to 0. Otherwise, setting a new target
temperature later will initiate a ramp to that target temperature.
