Ex Em (250 - 900.0) nm
250 350
Press numeric keys (to input 2 5 0 to 9 0 0) and then ENT key.
™
This wavelength is settable within a range from 250 to 900 nm in increments of 1 nm.

For canceling the input emission wavelength value, press the ESC key or
V
key. The 1st monitor
screen returns.
™
Pressing the
U
key enables you to return to the excitation wavelength setting without changing

• USE PROG (whether to use time program or not)
• PMT VOLT (photomultiplier voltage)
• OTHERS
1. Setting the OFFSET
The OFFSET is a set input signal amount that is added to the actually measured value for output.
a. Press the UTLTY key.
