Method check at start
on | off (Default value: on)
If this option is activated, then the following tests are carried out at the
method start.
￭ Are the required control and peripheral devices connected?
￭ Are the titrant and the sensor on hand?
￭ Have the monitoring intervals expired?
￭ etc.
NOTE
We recommend that the method check only be deactivated if the titra-
tion must begin immediately after the start of the determination (e.g.
with very rapid reactions such as enzyme-catalyzed reactions). If the
method check is deactivated, it could happen that the determination
run will be interrupted, e.g. because devices, titrants or sensors are not
on hand.
The following settings can be implemented for a connected USB Sample
Processor:
