Omega Model CYD211 User’s Manual
Operation 3-5
3.5.2 Curve
Selection
The Model CYD211 supports a variety of temperature sensors sold by
Omega and other manufacturers. After the appropriate sensor type is
selected for the input (Paragraph 3.5.1), an appropriate temperature
response curve may be selected. The Model CYD211 can use curves from
several sources. Standard curves are included with every instrument and
numbered 1 thru 7. A single user curve can be loaded via the serial interface
when a sensor does not match a standard curve. CalCurve option can be
stored as the user curve at the factory or by the customer. The complete list
of standard curves built in to the Model CYD211 is provided in Table 3-2.
Curve tables are listed in Appendix A of this manual.
During normal operation, only the curves related to the input type selected
are displayed. If the curve you wish to select does not appear in the
selection sequence make sure the curve format matches the recommended
format for the input type selected. Refer to Table 3-1.
NOTE
: The sensor reading can always be displayed in sensor units.
If a temperature response curve is selected for an input, its
readings may also be displayed in temperature.
To select a curve, continue from the input type selection (Paragraph 3.5.1)
or press the
Select
key, use the
s
or
t
key to select "
input
," then press
the
Enter
key twice. The display will show the curve currently assigned to
the input. If no curve is attached “
none
” will be displayed. Use the
s
or
t
keys to cycle through the temperature response curves. When the desired
type appears, press the
Enter
key. Proceed to Paragraph 3.5.3 to select the
display units or press the
Select
key to return to the normal display.
