2. Set up a two-temperature CYCL program with the following parameters:
• Setpoint #1 Temperature =
95
°C
• Hold Time =
2:00
minutes
• Ramp Time =
0:00
minutes
• Setpoint #2 Temperature =
40
°C
• Hold Time =
2:00
minutes
• Ramp Time =
0:00
minutes
• Cycles =
99
Note:
Refer to the
GeneAmp

PCR System 9600 User’s Manual
(PN 0093-
8660) for details on how to set up a CYCL program.
3. On the third cycle, measure the temperature of well A1 90 seconds into Setpoint
#1 (95 °C setpoint temperature) using the digital thermometer. The time-
remaining clock on the run-time display reads “0:30” (30 seconds). Record this
temperature.
4. Again on the third cycle, measure the temperature of well A1 90 seconds into
Setpoint #2 (40 °C setpoint temperature) using the digital thermometer. The
time-remaining clock on the run-time display reads “0:30” (30 seconds). Record
this temperature.
The figure below shows when to measure the temperatures.
5. After you measure the second temperature of well A1, turn the cover knob
completely counterclockwise, then slide the heater cover back.
6. Move the probe assembly to the next well to be measured.
7. Slide the heater cover forward, then turn the cover knob clockwise until the
white mark on the knob and the white mark on the cover are aligned.
8. Repeat the measurements on wells A4, A8, A12, C1, C4, C8, C12, E1, E4, E8,
E12, H1, H4, H8, H12.
Note:
The temperature display on the digital thermometer may not match the
temperature display on the GeneAmp
®
9600 because the heated sample block
cover affects the probe temperature. If you suspect any temperature calibration
problems, perform the calibration verification test that is described on
