1. Principle of Operation

ATP bioluminescence detector converts invisible ATP concentration to visible light output by bioluminescent chemistry technology, to display a quantitative result of microbial population indirectly. The result is a number from 0 to 9999 in Relative Light Units(RLUs).  RLUs are not a kind of tangible unit of light measurement, but they can provide a real method to the ATP bioluminescent test. In this application, 1 RLU is roughly equivalent to 1fmol of ATP.

RLU value is compared with the result threshold set by user to offer an overall result, which is pass, caution or failed

In order to ensure that you can get timely and accurate testing result by ATP bioluminescence detecting system, please note the following:

Before you begin, please read this user's manual carefully.

ATP bioluminescence detector should be auxiliarily used with the ATP sampling swab.

 

2. Preparation for Use

Before you begin, please ensure you have read this user's manual carefully and understood the system composition and method of application of this instrument. Please confirm the integrity of the product you bought according to the elements noted in the user's manual.

2.3 instrument indication 

 

 

Saving introduction:  

    

 

 

 

The testing code is a three-digit number from 001 to 999. The number “1” after testing code refers to group one, and “2” refers to group two. For example, “048 2” can be regarded as the 1048^th sample.

2.4 Fitting the batteries

The instrument is designed to operat from 2 AA batteries. The batteries are fitted by openning the battery compartment cover on the back of the instrument, and inserting two batteries with the positive end towards top of the instrument. After fitting the batteries, the instrument powers on automaticly, and enters into clock setting mode. Date and time setting is discribed in Section 4.  

     Caution: be careful not to swap the batteries’ poles over, for this may destroy the electronic system of instrument

     Tip: for better results, please use the batteries with good quality and replace them as soon as they become low.
