Description
Do a check of the magnetic stirrer. Push the up and down arrow keys to increase or
decrease the stirring speed.
This option is not available for all sensors. The option shows continuous
measurement data with connected sensors to quickly check measurements. The
installed applications and the automatic additions to the sample are set to off.
Continuous measurements are not temperature compensated, so measurement
differences may occur in the same sample between continuous measurements and
measurements that use installed applications with temperature compensation.
See the number of days remaining for maintenance tasks. After doing a task, push
Reset to set the number of days remaining to the default value.
See the list of maintenance tasks. Push Edit to change the default value.
Use this option to replace the reagents. Obey the instructions on the display.
