222DS BENCHTOP SHAKING INCUBATOR Quick GuidePage 11. BASIC OPERATION Press POWER switch on control panel. Shaking incubator automaticallydetects power supply frequency F50 or F60 and shows it on display. Likewisethe shaking incubator is then set to last saved parameters. Press and hold encoder knob for more than 2 seconds. Temperaturesignal light blinks. With rotating encoder clockwise (+) or counter-clockwise (-),set temperature to desired value. If you want to use the shaking incubator without temperature regulation -set OFF on display. You get OFF function on display, when you rotate encoderunder 0.0°C or above 70.0°C. Press encoder knob. Speed signal light blinks. With rotating encoder clockwise (+) or counter-clockwise (-), set rotating speed to desired value. If you want to use the shaking incubator without shaking - set OFF ondisplay. You get OFF function on display, when you rotate encoder under 20RPM or above 300 RPM. Press encoder knob. Time signal light blinks. With rotating encoder clockwise (+) or counter-clockwise (-), set time to desired value from 1 min to 99 h. If you want to set Time to hold (continued operation) - set HLd on display.You get HLd function on display, when you rotate encoder under 0.01 min orabove 99.0 h. Press START/STOP key once to exit the changing of parameters. You arenow in starting mode. Only signal light of the last changed parameter shines.Note: You always change the parameter, whose signal light blinks -temperature, speed or time. You can always change one, two or threeparameters. To exit the changing of parameters, always pressSTART/STOP key once. Press START/STOP key to start the operation. Run signal light shines. Shaking incubator counts down the time from setvalue.You can move between the values of time and speed during the operation, bypressing the encoder. These two values are shown alternately on bottom display.
