Page 3: Principle Of Operation
ATP bioluminescence detecting system 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). -
Page 4: Preparation For Use
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 notedin the user's manual. - Page 5 Elements of ATP bioluminescence detecting system Liquid Crystal Display：display test procedure and result Unit lid：kill the light Lable：display the instrument type and serial number Battery compartment：fit two AA batteries button：check last test result, and menu selection Down button：check next test result, and menu selection Start button：start test Threshold set...

- Page 8 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 sample. Fitting the batteries The instrument is designed to operat from 2 AA batteries.
- Page 9 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. 3. Basic operation 3.1 Power on the instrument Press the button, and the instrument will beep once and display the startup picture.
- Page 10 Tip:During self-calibration, there must be no ATP Swab in the instrument and the lid must remain closed. If the icon is flashing, close the lid. The instrument will automatically perform the self-calibration routine (the flashing CAL icon) under the following circumstances; a) When the instrument is in continuous operation for a prolonged period of time (typically >30 minutes), and b) The instrument is used in an environment where the...

Page 11: Ready For Use
a) the operating temperature is higher than normal range, b) The instrument is stored at the temperature exceeding normal range:to make the instrument adopt to normal temperature range, and c) the instrument is damaged or in fault. 3.3 Ready for use： Once the instrument has successfully performed its self-calibration, it is ready to perform a measurement: The detection procedure is discribed in Section 6.1... - Page 12 performing a mesurement. Power Saving Standby Mode If the unit is turned on and has stood by for more than 10 min(on operation for more than 10 min), it will automatically enter a power saving standby mode. To turn the unit back on, please press the button 3.6 Low Battery Indicator icon indicates the state of the batteries...
- Page 13 4. Clock Setting With the unit turned on and ready for a measurement, press button to display the current date and time. To change the time and date, press the button. Then use the buttons to change the flashing value, and the button to accept each new value in turn.
- Page 14 5. Result Thresholds The instrument can store up to 100 thresholds (0 to 99),each of which defines a pair of upper and lower thresholds for the measurement result. Note: the different thresholds indicate specific sanitary requirement of different testing sample. For the details how to choose the thresholds, please contact your local hygiene and epidemic prevention department, or set your own thresholds.
- Page 15 TIP:Pressing the button again will exit this set-up mode, leaving the thresholds number unchanged. 5.2 Changing the Thresholds Range Press the button, use the buttons to select the required thresholds number , and then press the button. Afterwards, use the buttons to first change the value of the upper threshold followed by the button;...
- Page 16 the thresholds number, the value of upper and lower threshold and test data number(68 indicates there are 68 test results saving in the instrument) TIP: When the stored test results take up more than 95% of the memory, the MEM icon will flash. When the memory is completely full, no more tests can be performed until the memory has been deleted or uploaded to the PC(see to section 6.3 and 7)
- Page 17 4.Press the button and wait 15 seconds for the result to be displayed While the measurement is being performed, the display shows the new test number while the timer counts down from 15 to 0 seconds: TIP: For consistent results, always keep the unit upright and steady while it is performing a measurement to ensure that the liquid in the ATP swab device is at the bottom of the tube.
- Page 18 The indication of icons: ―――――――――――――――――――――――――― Test result≤ lower threshold Test result＞ lower threshold≤ upper threshold Test result＞ upper threshold ―――――――――――――――――――――――――― TIP: After measurement, make sure to remove the swab to prevent the liquid leakage of swab and damage the instrument 6.2 Viewing Stored Test Results With the unit ready to perform a reading, the previous stored test results can be viewed by pressing the...
- Page 19 The display then shows the latest test result, with the MEM icon lit and the test number flashing. Press the button to scroll backwards through the stored test results and the button to scroll forwards. Press the button to view the time and date that the test was performed.
- Page 20 6.3 Deleting the Results Memory The results memory can be completely deleted by entering the results review mode (see section 6.2 above) and then pressing and holding down the button for more than 2 seconds. The display then shows the total number of results that will be deleted, with the DELETE? Icon flashing.
- Page 21 Tips: If installation program can not appear automatically, please open CD-ROM folder from “my computer”, then manually apply for installation. After installing, please press transmission shortcut key for transferring. Data transmission function Run transfer function by “start” button, a dialogue box will be opened as follows:...
- Page 22 Connect the detector to a USB interface on the cpomputer using USB cable (provided by the unit); （1）Connect one joint of cable to USB Mini interface; （2）Connect the other joint of cable to USB port on the computer; Next, choose appropriate connection port from alternative menus:...
- Page 23 Then, choose a file store type, an Excel data document or a blank text document: Tips: Excel document may be safer, because its data can not be modified, so you must install Microsoft Excel on the same computer, thereby saving the results as Excel form. The next step is naming the report.
- Page 24 The apparatus will try to connect with the instrument, if successful, “PC”PC will be displayed on the LCD of instrument. The results can be tranferred to and saved on PC at this moment, and 2000 results can be saved in 1 min. Warning: Excel is forbidden during the transfer and saving of data, for the possibility of destroying data.

- Page 29 Remark:Limited value After cleaning to the standards required for normal operation, the surface is inspected and the results recorded. The same wiping technique should be used for testing, and five different times should be selected for testing at the same location. This shows the standards that can be achieved after regular cleaning.
- Page 30 For example: Clean = (10 + 15 + 8 + 19 + 10) / 5 = 12.4 ≈ 2. It is obtained by multiplying the pass value by 2 by the limit value. For example: not passed = 12.4 × 2 = 24.8 ≈ 25 3.
