7.8 Using Calspeed
The Calspeed function, which is set in the CAL screen (see Figure 20 above), is used to
calibrate the speed of the shaking mechanism. Calibrated at the factory, speed does not
need to be recalibrated until a major operating component (e.g., drive belt) is changed.
NOTE:
Prior to calibrating the speed, make sure that the platform is properly secured
to the subplatform, and any flasks present are secured.
When the shaker is running, the CAL screen shows the indicated RPM value. If you wish
to calibrate the speed, set the speed to a value that can be measured— a setpoint of 250
RPM works well. The use of a strobe is recommended for accuracy. If, after measuring
the actual speed, you wish to adjust the indicated value:
1. Click the Control Knob in.
2. Set the new value.
3. Click the Knob in again to save the setting.
4. Turn the shaker
