Description
[
TEMP
]
Pressed to enter run temperature (using the keypad), from –20°C to
+40°C.
• The minimum allowable set temperature depends on the set speed
and the rotor in use. If a temperature is entered that cannot be
achieved by the rotor at the set speed, the TEMP°C field will flash.
• The maximum achievable rotor temperature depends on the fric-
tional heat generated inside the chamber during operation. At low
run speeds or low ambient temperature, the centrifuge may not be
able to achieve some higher temperatures.
• If, during acceleration, the system identifies a rotor different from
the rotor entered by the user, or if the set speed is changed during
operation, the set temperature may no longer be achievable. If this
happens, the Temp°C field will flash indicating that a different
temperature must be entered.
[
A/D
]
Pressed to enter acceleration and deceleration rates that will maintain
optimum separation while protecting samples. When [
A/D
] is pressed,
the Accel: field flashes, prompting you to enter an acceleration
setting. Pressing [
A/D
] once more moves the cursor to the Decel: field.
Available acceleration rates are maximum, slow, and timed (1 to
10 minutes from 0 to 500 rpm). Available deceleration rates are
maximum, slow, timed (1 to 10 minutes from 500 to 0 rpm), and
no brake (off).
[
OPT
]
Pressed to put the centrifuge into program mode, where you can enter
run parameters into memory for later use. Up to thirty two-step
programs can be stored.
KEYPAD
The keypad is used to enter numerical run parameters and to enter
program numbers. In addition to keys 0 through 9, the keypad
includes [
±.
] (plus/minus/decimal) and [
CE
] (clear entry) keys.
The [
±.
] key is used to enter a decimal point when typing in a rotor
number (for example, 25.50) and to enter a temperature setting below
0°C (for example, –2°C).
The [
CE
] (clear entry) key clears any parameter in the active field.
Pressing [
CE
] will also clear some diagnostic messages. If a diag-
nostic message does not clear when [
CE
] is pressed, see Section 4,
TROUBLESHOOTING
