Maximum Samples Exceeded
Warning Message: “Maximum number of samples that can be run
on this chip has been exceeded. Please install new chip.”
Chip Primed for Different Assay
Warning Message: “Assay for which chip was primed is different
from run assay or unknown.”
HV Check Failed
Warning Message: “HV check failed.”
Possible Causes Recommended Actions
Chip has already been
used to process the
maximum number of
samples.
Replace the chip with a new chip. Prepare and reprime
the new chip as necessary.
Possible Causes Recommended Actions
The last assay that the chip
was primed for does not
match the assay that is
going to run.
1. Touch the No button, remove the chip, refresh with
appropriate reagents, and repeat the chip priming step.
2. Touch the Yes button to skip repriming and continue
with the run using the current chip.
Possible Causes Recommended Actions
1. Dirty electrode block. 1. Run the Current Leak Diagnostics test (see
page 152). If test fails, clean o-rings and electrode
block (see page 138).
2. Re-priming can sometimes clear chip clogs. Open
the front door, close the door, and prime the chip. See
the LabChip GX Touch/GXII Touch Assay User Guide
for troubleshooting.
3. If the problem is not resolved, contact PerkinElmer
Technical Support (see page 3).
2. Clogged chip.
