Watson-Marlow 323Dz User Manual 21
15 The main menu
In addition to their functions in other opera-
tions (see 15.2 Manual control), the following
keys have specific actions in menu screens:
STOP: In general, STOP functions as a
"go back" key, taking the user up one
menu level without making a change. In a
numeric entry screen, STOP resets the
pump to the previous value.
UP: The UP key is used in menu item se-
lection: it moves a highlight up the menu.
When a numerical entry screen is dis-
played, pressing UP increases the number
displayed.
DOWN: The DOWN key is used in menu
item selection: it moves a highlight down a
menu. When a numerical entry screen is
displayed, pressing DOWN decreases the
number displayed.
START: During Dose setup, press the START key to leave setup and begin the
dose batch via the priming screen. When the priming screen is displayed, press
and hold the START key to operate the pump at full speed and prime the pump.
DIRECTION: During Dose setup, the DIRECTION key reverses the direction of
pump rotation instantly.
RETURN: The RETURN key functions in a similar way to the "enter" key of a
personal computer: it confirms key-presses made immediately before. In menu
item selection, it triggers the action or display selected from a menu using the
UP and DOWN keys.
The options are Dose, Calibrate, Manual, Setup.
Dose programs the pump for dispensing.
Calibrate sets the pump for accurate flow. The flow rate of the pump is gov-
erned by the tubing. Factory default is for the 501 pumphead with 8mm bore
tubing or the 313/314 pumphead with 8mm bore tubing.
Manual for keypad control of continuous fluid transfer.
Setup prepares the pump for operation.
Use the UP and DOWN keys to move between the menu options. Press the RETURN
key to select the option.
Press the STOP key to exit a sub-menu and move back up to the previous menu. Or
press the STOP key when changing values on the display to revert to the original
value.
