Pre-set selector:
This three way switch allows
selection of either variable speed (VAR), or one of
the two pre-set speeds (P1 and P2).
Speed controller:
This knob controls the paddle
speed in conjunction with the press to set switch.
Turning it to the right increases the speed,
turning it to the left decreases the speed.
Digital display:
This screen displays the paddle
speed in rpm.
Operation
(see Fig 1 & 2)
Place the unit on a firm, level surface and
connect to the mains supply. Leave sufficient
space to access the side IEC socket.
Turn the mains and lamp switch on and observe
the fluorescent lamp illuminate. Use the blue
knob to move the stirrer paddles up or down as
required.
To position a beaker, lift the paddle up to its
maximum height using the paddle lift and place
the vessel over the illuminated base. Once the
samples are in position, lower the paddles into
the beakers to the required depth.
Selecting a variable speed
Set the Pre-set Selector to the VAR (variable)
position. Hold down the 'Press-to-set' switch and
turn the Speed Controller until the desired speed
in rpm appears on the digital display.
Selecting a pre-set speed
Set the Pre-set Selector to the P1 position. To
change the fixed speed, insert the blade of a
small screwdriver and turn the screw control
clockwise or anticlockwise until the desired speed
in rpm appears on the digital display. Now every
time the Pre-set Selector is put to the P1 position,
the stirring paddles will rotate at that speed.
If a second pre-set speed is required, set the
Pre-set Selector to the P2 position and repeat the
procedure.
