Setting Operating Parameters For Immediate Change - PerkinElmer 200 UV/VIS Series User Manual

Using Manual Mode

Setting Operating Parameters for Immediate Change

In Manual mode, you can change the detector's operating parameters at any time. Setting a
parameter on the Manual mode screen takes effect as soon as you press the Enter key to
move to another field. A set of operating parameters cannot be stored (saved for recall at a
later time). However, the set of parameters that appears on the display when you shut off
the detector are the parameters that appear when you restart the detector.
To set the detector's operating parameters follow the procedure below.
Display the Detector Manual Settings Screen. For more information, see "Viewing the
1
Detector Manual Settings Screen" topic earlier in this chapter.

The (wavelength) field is highlighted.
Use the numeric keypad to enter the wavelength in nanometers. Press the right arrow

key or the
and then move to the RANGE field.
Use the numeric keypad to enter the range. The range indicates the full-scale absor-
3
bance range for the recorder output. The range applies to the 10mv output recorder.
The range value can be set from 0.0005 to 3 AU. This value sets the sensitivity of the
recorder. The larger number makes the recorder less sensitive, and the smaller num-
ber makes the recorder more sensitive.
Press the right arrow key or the
RSP/PW field.
