Answer
Set the units to be used for measurement results.
You can set a threshold for each measurement item. When a measurement value exceeds the threshold, the instrument outputs a measurement value alarm.
NOTE: When [User Authentication] on the [System Policy] screen is “Enabled,” the following operations are only available to an Administrator or a Main user level user. These operations are not available to User or Guest level users.

For calibration and validation functions, however, the display units are fixed to ppb for TOC, μS/cm C for conductivity, and ˚C for temperature, and cannot be changed.
