TROUBLESHOOTING
Intermittent or no power
Check the power adapter plug connection to the wall outlet as well as the power adapter cable connection
to the instrument. Be certain power is provided to the wall outlet. If you are using the battery pack, make
certain all batteries are properly and firmly inserted and that the battery pack cable is connected to the
instrument.
Sudden, dramatic change in expected values
Memory full or corrupted. Check available memory (pg. 15), if less than 80000 or cannot view data, erase
data from device. Data should be downloaded as often as possible and after that the device memory should
be erased.
The sample may have become contaminated or the sample tube scratched.
Be certain the top of the optics chamber is completely closed. Wait 5 seconds after top is closed before
measuring. Check the G factor (calibration screen), power surges can cause it to change to 0.001.
Recalibrate the instrument and retest (pg. 10).
Blank Intensity 0
Assay Time set to 0. Go to ‘Setup’ menu and set ‘Assay Time’.
PMT voltage set to value less than 80. Go to ‘Setup’ menu and set the ‘PMT value’.
Lamp out, PMT not working, Main board error. Flip open the lid and press Read. Check to see if the lamp turns
on and off. If the intensity is still zero, the unit needs servicing.
Sample Intensity 0 or mP 0
Blank not read. Add new sample to buffer and read blank intensity then add tracer (conjugate) and read the
sample intensity.
No tracer (conjugate) added. Add new sample to buffer and read blank intensity then add tracer (conjugate)
and read the sample intensity.
If problem persists contact Ellie instrument service (contact information is located at the bottom of this
page).
If the housing of the instrument has been removed and the optics compromised, stray light may have found
its way into the chamber. Such actions VOID the WARRANTY.
If after identifying the problem and trying the suggested solution, the problem persists,
