Configuring the Oven
Oven configuration sets maximum temperature, equilibration
time the cool down mode, and the cryogenic setpoints, if cryo is
installed.
Maximum temperature Maximum allowable oven temperature
setpoint. Some accessories, such as the valve box, valves and

the accessories are not damaged. Oven setpoints are verified as
they are entered; a message is displayed when an entered
setpoint is inconsistent with a previously defined maximum.

the oven temperature setting. The Equilibration time setpoint can
be 0 to 999.99 minutes.
