Run temperature can be set from 2 to 40°C. If no value is entered, the
instrument automatically selects the last entered temperature. (If all
previous entries have been cleared, 25°C is selected as the operating
temperature.)
Result
The TEMPERATURE °C display flashes.
Entered temperature appears on the TEMPERATURE °C display.

NOTE
].
The instrument provides a choice of ten acceleration rates and eleven
deceleration rates to protect the gradient and sample-to-gradient inter-
face. Table 3-1 lists these rates by keypad number. The acceleration
time is the time it takes a rotor to reach 5000 rpm from rest. At
5000 rpm, maximum acceleration takes over until the rotor reaches
set speed. The deceleration time is the time it takes a rotor to decel-
erate from 5000 rpm to rest; from set speed to 5000 rpm, the rotor
decelerates with full dynamic braking. If no rate is selected, the
instrument automatically accelerates and decelerates at maximum rate
and the ACCEL and DECEL displays remain blank.
], then enter the correct value.)

If the rotor temperature rises more than 3°C
above the set temperature for more than
40 minutes, the user message TEMP will flash
on the control panel. If a run is in progress, the
rotor will decelerate to a stop (see
, Section 4).
