Configuration (Conf)

You only have to enter the Configuration details one-time; the 402 keeps this information in its memory, even after you switch off. The next time you switch on the 402, the Configuration and all Methods previously saved as files will be available to modify or run.

The software must be given details about syringe sizes, flow rates, etc. You enter this information using the configuration function, which you access by pressing the Conf soft-key (see Configuration Screen).

As a minimum, you must enter the volume of syringe(s) that you are going to fit to your 402, check that the default flow rates are appropriate (or enter suitable values), and check the transfer (probe) tubing volume is correctly specified (standard is 2 mL).

The use of the soft-keys is as follows:

•Vol is used for the probe (transfer) tubing and ‘Air gap’ volumes,

•Syr is used to enter syringe related parameters and activate the syringe exchange function.

•Flow is used to enter default flow rates for liquid coming from the reservoir,

•Count is used to consult or to reset various counters (see Chapter 5),

•Etc is used to switch on and off the Beeper and Autorefill function.

Volume(s)

Check that the configured volume for the probe tubing is the same as the size fitted.

Press the Vol soft-key, you see the Tubing Volume Screen.

Next is used to go to the next screen,

Chge is used to select the tubing size (see Tubing Volume Screen),

Prev is used to go to the previous screen (see Air Gap Volume Screen).
