Temperature calibration verification test
Evaluating the
results
When the thermal cycler completes the calibration verification test, one of two
screens opens, depending on the results. See the table below to evaluate the results.
Note:
As a result of the Temperature Tolerance Stack, between the sample block,
temperature probe and thermometer, the instrument firmware is programmed to
accept a Pass/Fail result of ±0.75 °C. Therefore, passing results may vary from
84.25 °C to 85.75 °C at the 85-degree setpoint and 44.25 °C and 45.75 °C at the 45-
degree setpoint. Ranges greater than
±
0.75 degrees cause the test to fail.
Ending the test
1. Press
F5
(Exit).
2. Remove the 0.2-mL probe assembly from the sample block.
3. Power off the digital thermometer, then clean off the oil.
Wait for the sample block to reach room temperature (~25 °C), then remove the
2720 temperature verification frame from the sample block.
PHYSICAL INJURY HAZARD.
Hot Surface. Use care
when working around the heated cover and sample block to avoid being burned
by hot components.
4. Clean the oil off the sample block.

• If the test fails, repeat the procedure to make sure that the
thermometer was not misread or that data-entry errors were
not made.
