9.8 Using Calspeed
The Calspeed function, which is set in the CAL screen (see Fig. 34 on p. 50), 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.
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 OFF, wait a few seconds, then turn the shaker back ON.
9.9 Power interruption
In the event of a power failure, the Innova 44/44R Shakers are equipped with an automatic restart
function. The shaker’s non-volatile memory retains all stored information.
If the shaker was in operation prior to the power interruption, the shaker will begin to operate at its
last entered setpoints. The alarm/POWER display will flash, indicating that a power interruption
has occurred. Turn the Control Knob in any direction to acknowledge the visual alarm. The
flashing will stop.
9.10 Slide-out platform
The Innova 44/44R is equipped with a slide out platform mechanism as a standard feature. This
allows you to easily slide the platform out of the shaker for easy access to the platform without the
need for tools.
To operate the platform slide-out mechanism:
1. Make sure platform has stopped moving.
2. Rotate cam lever located on the subplatform (see Fig. 35 on p. 51) 180 ° clockwise. It should
be pointing to the left.

Hint!
Prior to engaging the Calspeed function, make sure that the platform is properly secured to the
subplatform, and any flasks present are secured. Run the unit at approximately 250 RPM to
ensure stable operation prior to calibration.
