Methods

 

Getting Started 

 

Installing the 
Qubit

®

 2.0 

Fluorometer 

The Qubit

®

 2.0 Fluorometer is a stand-alone instrument that does 

not require a connection to a computer. 

1.

 

After unpacking the instrument, place the instrument on a flat, 
level, dry surface. 

2.

 

Plug one end of the supplied power cord into the Qubit

®

 2.0 

Fluorometer. To the other end attach the appropriate plug 
adaptor, based on the electrical outlet configuration in your 
country. 

3.

 

Plug the power cord into the electrical outlet. Be sure to use 
only the power cord supplied with your instrument. Powering 
the instrument with an unapproved power cord may damage 
the instrument. 

4.

 

The instrument is automatically powered on when it is 
plugged in.  

5.

 

To power down the Qubit

®

 2.0 Fluorometer, unplug the 

instrument.
