Appendix
Temperature Controller
The controller allows the temperature profile to be programed for each test.
This profile will be divided into at least two segments. Each segment controls
a portion of the test and determines the temperature, time, and behavior of
the test cell during a specified time period.
The four buttons along the bottom of the display provide access to the
temperature profiles. Begin by pressing the “PAGE” button three times. The
display will read “Prog List”. Now, press the “SCROLL” key repeatedly until
the setting you wish to change is shown on the display. Then press either
arrow key until the appropriate value is displayed. Once a value has been
chosen, press the “SCROLL” key again to select a new setting.
The first group of settings should read as follows:
Setting
Value
Prg1 1
Hb OFF
Hb.u 0.0
Rmp.u min
Dwl.u min
Cyc.n 1
These settings will be the same for every test. Do not change them.
1.
Begin by defining the first segment of the test.
a. Press the “SCROLL” key repeatedly until “Seg” appears on the display.
b. Press either arrow key repeatedly until “1” appears on the display.
This is now editing segment 1.
2.
The first setting is “Type”.
a. Press the “SCROLL” key until the word “Type” appears on the display.
b. The available options are “rmp.r”, “rmp.t”, or “dwell”. Press either arrow
key until the appropriate value appears on the display.
Rmp.r
programs the controller to steadily increase the temperature by
a specified rate (degrees per minute). If this value is chosen, the next
option will be “Tgt”, which is the target temperature and then “Rate”
which is the desired rate the temperature will increase.
Rmp.t
increases the temperature over a specified time interval
(minutes). If this valueis chosen, the next option will be “Tgt” (target
temperature) and then “Dur” (duration in minutes).
Dwell
holds the temperature at its current setting for the duration
specified.
