Guardian 5000 Series EN-17

2.3 Controlling the Stirrer

STIRRING OPERATING TIPS

The stirrer increases speed at a steady rate until the setpoint is reached. If the stirrer is not reaching its setpoint: 1)

the stir bar may be too large, 2) the liquid may be too viscous, 3) the setpoint speed may need to be reduced.

Additionally, the magnetic strength of stir bars reduce over time and may need to be replaced.

When heating and stirring a reaction vessel within an oil bath or similar set-up, the stirring function will stir up to

approximately one inch (2.5 cm) from the top plate. The stirring speed will vary according to liquid viscosity, spin

bar length, and distance from top plate. Adjust one or all of these to achieve the desired stirring speed. For

example: the closer the reaction vessel is to the top plate, the strong the magnetic connection between the unit and

the stir bar.

1. Rotate the right knob (D) to control the speed setting

(S).

a) Clockwise rotation will increase the speed

setting (S).

b) Counterclockwise rotation will decrease the

speed setting (S).

2. To turn on the stirrer, press and hold the right knob

(D) until the unit beeps and the stirrer indicator (T)

illuminates.

a) The unit will beep once to confirm the stirrer

has been turned on.

b) The stirrer indicator (T) next to the “RPM”

symbol will blink to indicate that the stirrer is

on and ramping to the target speed.

c) Once the stirrer has reached the target speed,

the speed setting indicator (R) will disappear

and the stirrer indicator (T) will stop blinking

and remain illuminated.

3. To change the speed setting while the stirrer is on:

a) Rotate the right knob (D) to the new speed

setting.

The speed setting (S) will blink to indicate that

the speed setting is not confirmed.

b) Briefly press the right knob (D) to confirm the

new speed setting.

The speed setting (S) will stop blinking once

the new setting is confirmed.

Note: If the speed setting (S) remains idle without

confirmation for 6 seconds, it will reset to the

current setting.

4. To turn off the stirrer, press and hold the right knob

(D) until the unit beeps and the stirrer indicator (T)

disappears.

a) The unit will beep once to confirm the stirrer

has been turned off.

b) The stirrer indicator (T) next to the “RPM”

symbol will disappear to indicate that the

stirrer is off.

c) The speed setting indicator (R) will illuminate.

EN-18 Guardian 5000 Series

2.4 Controlling the Top Plate Heater

1. Rotate the left knob (C) to control the heat setting (L).

a) Clockwise rotation will increase the heat

setting (L).

b) Counterclockwise rotation will decrease the

heat setting (L).

2. To turn on the heater, press and hold the left knob

(C) until the unit beeps and the heater indicator (M)

illuminates.

a) The unit will beep once to confirm the heater

has been turned on.

b) The heater indicator (M) will illuminate next to

the “°C” symbol to indicate that the heater is

running.

c) The current heater temperature (L) will be

alternately displayed with the heat setting (L)

in the top left region of the screen.

d) When the heater temperature (L) is above

40°C, the hot top caution indicator (Q) will be

illuminated.

3. To change the heat setting (L) while the heater is on:

a) Rotate the left knob (C) to the new heat

setting.

The heat setting (L) will blink to indicate that

the heat setting is not confirmed.

The heat setting indicator (N) will illuminate.

b) Briefly press the left knob (C) to confirm the

new heat setting.

The heat setting (L) will stop blinking once the

new setting is confirmed.

If the heat setting (L) remains idle without

confirmation for 6 seconds, it will reset to the

current setting.

4. To turn off the heater, press and hold the left knob

(C) until the unit beeps and the heater indicator (M)

disappears.

a) The unit will beep once to confirm the heater

has been turned off.

b) The heater indicator (M) next to the “°C”

symbol will disappear to indicate that the

heater is off.
