The Cimarec unit has a hard switch on the left side of
the unit. The unit may be powered on by pressing the
hard switch. When the unit is turned on, the unit will
initialize and then "SP or HP" will be displayed on the

Setting the Stirring Speed

+
Your Cimarec stirring hot plate has an electronic feed-
back speed control which will maintain a speed set-point
from 50 rpm through 1500 rpm at ±5.0%. (Maximum
speed is dependent on viscosity of the solution.)
To set the speed, turn the STIR knob to your desired
setting. Turn the knob clockwise to increase the speed
or counter-clockwise to decrease the speed with 10 rpm
increments. To discontinue stirring, turn knob counter-
clockwise to OFF.
