Troubleshooting

Remove the plunger (silicone balloon that goes down over the slide, behind the door) from the device. It is easier to let the plunger go down first (Setting-Plunger). Clean the plunger with water or ethanol 70% and dry it. It is advisable to continue with the spare plunger from the case and change plunger each time.
Failed to read the QR code.
On the back of the slide is a QR code that is read by the QR camera. This is behind the door, under the glass at the bottom. This can also be cleaned with a damp cloth with water or 70% ethanol.
'Part of ch could not be detected'
In the slide under the sieve there are channels where an enzymatic reaction takes place. This is necessary to ultimately perform a spectrophotometric measurement. This error message means that these channels are not filled because the plunger cannot push the blood through the sieve.
Possible causes are:
- heparin blood is not swirled enough before pipetting
- serum blood is not centrifuged enough
- sample is too cold
- sample not pipetted accurately onto the slide
- insufficient sample pipetted onto the slide
- heparin sample is too viscous (hematocrit too high), especially in dehydrated animals, it is recommended to centrifuge the heparin sample first in these cases.
The device does not stay on time
