The LID key is used to open the lid of the centrifuge once it has come to a complete standstill The LID key can only be used when the display reads S This key cannot be used whilst the rotor is in motion Once the rotor has stopped the lid can be opened by pressing the lid key the display will show S O and the LED in lid key will be lit up This denoted that the rotor has stopped and that the lid is open The PULSE key is used when the operator wants a short spin without having to program a cycle The user can hold down this key and the centrifuge will begin to spin Once the user has let go of the button the centrifuge will gradually slow down and come to an eventual stop at the brake rate previously chosen Pressing the STOP key after releasing the PULSE key will increase the brake rate to the maximum even if the set brake rate is lower The parameter keys are used to adjust speed time RCF as well as acceleration and de acceleration rates Figure 1 2 shows each of their functions Increase a parameter value Select up to 9 predetermined programmes Figure 1 2 Decrease a parameter value Adjust speed and RCF Adjust Adjust time and acceleration from 1 99 minutes and braking V Setting the time as The user can m swill set select three the centrifuge to different rates run continuously with 1 being the fastest Each of the 9 programmes will allow you to set speed time acceleration and b
