SPECTRONIC 200E USER GUIDE

Using the Analyzer Mode

SPECTRONIC 200E User Guide

Thermo Scientific

The analyzer mode allows a laboratory manager to program sophisticated methods involving 
up

 

to four wavelengths, four factors, and a user–entered mathematical equation. Analyzer 

methods, once programmed, must be saved to a USB memory device for later re-use. The 
working screen of an analyzer method shows only the name of the method and the result 
(e.g.,

Figure 29

).

Figure 29. 

Using the Analyzer Mode

Loading a Saved Method

• If you select the 

Load Method

 option, the screen will display the names of all the 

methods saved on the attached USB memory device. 

• If no memory device is present, an error is returned. 

1. Select the chosen method using the 

 keys and press 

 to load it into the 

instrument.

Figure 30. 

2. After loading the method the instrument will prompt the user to place a blank solution in 

the sample compartment and press 

NOTICE    

Using the Analyzer mode requires that you store methods on a USB 

memory device that is formatted FAT32.
