Operation - Advanced Use

 

Counters

 

Under normal use you should expect to fit new (or

 

refurbished) syringes after 30000 cycles with water.

 

This feature is made easy by the 402, which automati-

 

cally counts the number of operating cycles performed

 

by the syringe(s) and valve. (A cycle is completed

 

when the syringe leaves its home position.) You

Syringe Counter Screen

should only need to reset these counters after

 

changing one or more of these items. To do this,

 

press Count, the Syringe Counter Screen appears.

 

Press Chge, then key in the number from which

 

you wish the new count to start, followed by ENTER.

 

Press Next to go to the second syringe (if fitted) or

 

to the valve.

 

Press Chge, then key in the number from which the

 

new count is to start, followed by ENTER. Do this

 

for each counter that you want to change; followed

 

by ESC to return to the Configuration Screen.

 

Other Items

 

Press the Etc soft-key; the Beeper Screen appears.

Beeper Screen

This is to set an alarm when an error occurs, and to

 

warn that liquid is going to be dispensed to waste.

 

To switch between ON and OFF, press the Chge

 

soft-key, then press ENTER to confirm.

 

Press Next to go to the Autorefill Screen. When you set

Autorefill Screen

Autorefill to ON, the left-hand syringe re-aspirates

 

diluent automatically for the next cycle, while you

 

are (for example) aspirating air via the probe. This

 

feature enables you to work faster with the 402.

 

To switch between ON and OFF, press the Chge

 

soft-key, then press ENTER to confirm. Press Prev

 

to go to the Beeper Screen. Press the ESC key to

 

return to the Configuration Screen.

 

Creating a Method (EDIT)

 

You use the keypad to enter the Method as a file

 

(one or more tasks used sequentially).

 

Key in the file number for your Method, then press

 

ENTER; press Edit. Now, one of two situations can

 

arise:
