2. Dispensing test function
2.1 Overview
This function does predispensing according to the predispense information specified in advance, and shows a
list of the results on the operation screen to make it easier to check the dispensing state and set the correct air
pressure. Optimal dispensing can easily be maintained by using this function to check and adjust the
dispensing state such as before starting daily production or when a recognition error occurs during operation.
The object here is a dispensing test so that unlike normal predispensing, there is no offset (correcting)
operation. The dispensing test can be started with the dedicated button on the Setup screen while in a reset
state, or started from the screen for selecting the next action that appears after a predispensing recognition
error occurs during automatic operation.
If making a specified number of dispensings at any liquid amount, see “4.1 Dispensing test (adjustment
screen)” in Chapter 6 for information on how to make the desired dispensing settings.
