Button on Wallac 1420
This button has different functions depending on how long you press it for and what is
happening when you press it.
If a plate has been measured, you can remove it, load a new plate and briefly press this
button to continue the assay with the same protocol as the plate just measured. However, if
you press this button for more than 2 s, the current assay will be stopped and a new assay
will be started with the current protocol. This will not work if the protocol barcode option is
selected.
If a plate is being measured and you press this button, nothing happens.
If no assay is running and you press the button for more than 2 s, then a new assay will be
started with the current protocol. This will not work if the protocol barcode option is
selected or the enhanced security mode is installed.
Note: make sure in all cases that you have loaded the correct plate before pressing the
button because the plate in the loading position (or the empty plate holder) will be taken
into the counter.
