4.2.1 Shaking Speed
The shaking speed is set at an appropriate speed for polymer dissolution, but can be adjusted by
using a trim potentiometer (Pot.) labelled 'Speed Control' on the front of the instrument. Turning the
Pot. Clockwise increases the shaking speed and anticlockwise decreases the shaking speed.
4.2.2 Turning the Shaker ON
The shaker is switched on and off by pressing the Shaker On/Off button.
The shaker may be operated in two modes; continuous shaking [Cont] or programmed shaking
[Prog]. The modes are selected by pressing the SHAKER TIMER button when the shaker is off and
using the up or down arrow keys to toggle between the modes. The mode selected is displayed on
the screen.
In the Prog mode shaker delay time (d) and shaker duration time (L) can be programmed. The delay
time (d) is the time in minutes before the shaker will shake after the shaker as been turned ON. The
shaker duration time (L) is the time the shaker will shake for after the delay time as elapsed.
Pressing the SHAKER TIMER button during a programmed shake cycle will display the actual time
remaining during the delay or shake period.
In the event of a power failure the unit will not continue to shake when power is restored.
