When you power on or reset your 2700 SELECT the Main Menu appears on the instrument
display.
Please select instrument mode
[RUN] [STANDBY] [MENU]
From Main Menu you may enter any of three modes by pressing the appropriate function key.
The modes are RUN, STANDBY and MENU. You may also transfer from one mode to another
using the function keys, however, there are limits to what submenus you can access. Refer to
Figure 3.1.
If you press [RUN] from Main Menu, the instrument initializes and self-calibrates. Once
calibrated it maintains a "sample ready" status. If 2 hours pass without a sample being
processed, the unit automatically transfers to STANDBY Mode, where reagents are conserved.
(In Section 5 you will learn how to change this 2 hour threshold value to better fit your
application.)
If you press [STANDBY] from Main Menu, the instrument flushes buffer through the Sample
Chamber that houses the Enzyme Electrodes. It then continues to flush buffer once an hour to
maintain fresh solution in the Sample Chamber. If you transfer from STANDBY to RUN Mode,
a calibration is initiated to update the calibration reference value stored in memory.
If you press [MENU] from Main Menu, you enter a series of submenus that allow you to
reconfigure your setup parameters, perform service functions and utilize diagnostic routines.
You will learn about MENU selections in Section 5.
