DELAYED START PROGRAM FUNCTION

When the run begins, the rotor will not accelerate past 3000 rpm until
the chamber pressure drops below 750 microns. At that time, the rotor
accelerates to set speed.
To vent the chamber, press
opened only when the vacuum has been completely vented and the
rotor is at rest.

As the rotor begins to accelerate, the green LED on the

blinking and remains on until the run ends or

The delayed start program function allows you to delay the start of a
run so that it begins and ends at the time you require—without you
being there to start the run. For example, if you require a four-hour
run to end at 8:00 am, you can program the instrument to hold the
rotor at a specified temperature and time at zero speed and then auto-
matically begin the run at 4:00 am.
