How to delete characters:
When the cursor is on a letter you wish to delete, for example the new name is shorter than the previous one, turn
the rotating button to the left or to the right until the letter disappears. Then press the button to validate the
deletion. The cursor then goes to the next position.
Repeat until everything is erased. When you have erased the last letter, press “esc.” twice.
Distribution mode
Each program must have at least one dispensing mode: dose, multi-dose or continuous.
To change this mode, select the line “MODE” and press the rotating button.
Then, by turning the button, make the display mode you want and validate by pressing the rotating button. The
cursor then goes to the next line (SPEED).
Pump speed
The speed is measured in RPM, that is to say, Revolution Per Minute. The pump speed and inner diameter of the
tubing condition the flow. (The flow also depends upon the viscosity of the liquid.)
To change the speed, select the line “SPEED” and press the rotating button.
Then by turning the button, change the number and validate by pressing the button.
Another method, to change the speed in an experimental mode:
Launch the program. When the pump is working, the speed is displayed on-screen and you can modify with the
rotating button. The last chosen figure is memorized in the program.
Inner diameter of the tubing
You have to enter and memorize this information for each program. It will then be useful to calibrate the pump.
To change this figure, select the line “TUBE” and press the rotating button.
Then by turning the button, change the figure and validate by pressing the button.
Note: after having changed the figure of the tubing’s diameter, it is recommended to make a calibration.
Power of the pump motor
You can choose the maximum power, economy (minimum) or automatic mode. In the automatic mode, the power
of the pump is settled according to the speed and diameter of the tubing.
Volume of a dose
If you have chosen the mode dose OR multi-dose, enter the volume in mL here.
Number of doses
In the multi-dose mode, the Media Pump dispenses several doses consecutively making a pause in between each
one.
If you choose the multi-doses mode, select the line “DOSES” and the number of doses to dispense.
