Countdown-Timer - Cole Parmer Digital Reversing Mixer 50004-00 Bedienungsanleitung

Countdown Timer
Turn the mixer on by pressing the power button. Set the desired speed by
pressing the "+" button. Press the multifunction button until the LED dot for time
is illuminated. Press the "+" to set the countdown timer in minutes. Press the
start/pause button to start mixing. Press the multifunction button to toggle the
display between speed, time and cycle. Mixing stops when time is completed.
Three beeps will sound. Note: Countdown Timer value cannot be changed during
operation.
xRx Agitation Cycle
Turn the mixer on by pressing the power button. Set speed as above and
countdown timer if desired. Press the multifunction button once more until the
indicator light for cycle is illuminated. Press the "+" to set the number of seconds
the impeller will rotate in one direction before changing directions. Press the
start/pause button. Note: xRx Agitation Cycle value cannot be changed during
operation.
For example: If set for 5 seconds the mixer impeller will turn clockwise for
5 seconds at the set speed then stop and change to turn counterclockwise for
5 seconds. This mixing pattern will continue until the pause button is pressed or
until the time is completed (if set).
The display will show the cycle seconds counting down during each direction
unless speed or the countdown timer is selected.
When the mixer is powered on, the default speed is 40 rpm, countdown timer is
0 minutes, and the xRx agitation cycle is 0 seconds. Previously set values will be
displayed if Auto Start is enabled.
The mixer will remember the original values set for speed, the countdown timer
and the xRx agitation cycle so that when the start/pause button is pressed again
the operations will repeat.
Speed can be changed (increased or decreased) while the mixer is running. Press
the multifunction button so the speed is displayed. Increase or decrease speed
by pressing the "+" or "-" buttons.
The countdown timer and the xRx agitation cycle can be changed only when the
mixer is paused and the indicator lights are solid.
The multifunction button can be pressed when the mixer is running to view the
status of each function.
For safety, a "soft start" has been incorporated into the mixer. The mixer will
ramp up to reach the set speed to minimize splashing.
