Temperature non-uniformity test
10. When you complete all measurements, be sure to:
• Press
F5
(Cancel).
• Remove the 20-µL probe assembly from the sample blocks.
• Power off the digital thermometer, then clean off the oil.
• Remove the 384-well temperature verification plates from the sample
blocks.
IMPORTANT!
Make sure the sample blocks are at room temperature (~25 °C)
before removing the reaction plates.
Evaluating the
results
When the GeneAmp
®
9700 completes the temperature non-uniformity test, the TNU
Performance screen opens. See the table below to evaluate the results.
If the...
Then...
Temperature of the
sample block wells is
uniform
“Pass” appears after each setpoint temperature.
Temperature variation of
the sample block wells
exceeds performance
specifications
“Fail” appears after the setpoint temperature(s) for which the
test failed.
• If the test fails, repeat the procedure to make sure that the
thermometer was not misread or that data-entry errors were
not made.
• If the test fails again, contact Applied Biosystems Technical
Support. See
“How to obtain support” on page viii
