Possible Cause
A non-96 collection software
has tried to establish
communications with a 377
instrument that has the 96-lane
option installed.
The EP voltage deviated
outside its tolerance range. The
instrument operation is paused.
Indicates one of the following:
Possible open or short
circuit exists with the
thermistor/cable connected
to J43 or J44.
Temperature of the plate in
an instrument with the
100k ohm thermistors is
21.9 °C or less.
Solution
Increase the CCD gain to
four:
a. Open 377-96 Collection.
b. In the Run window select the
Run module.
c. Double-click the small
document icon next to the
Run Module pulldown menu.
d. Change the CCD gain to
four.
Resuspend samples in less
volume (concentrate).
Solution
Install the 96-lane collection
software and firmware.
Call service.
One of the thermistors is not
functioning properly.
Schedule a service call, and
continue to operate the
instrument as usual.
This message may appear
when you launch data
collection software and start a
