16.6.6 Factory setup
For “Factory setup,” there is no item to be set by the user.
NOTE
This menu is for service engineers only. This section is protected by a password. Attempting to
change data in the factory adjustment menu without the proper instructions and equipment could
result in corruption of the instrument setup and damage the performance of the unit.
16.7 Display setup
This screen is used to make various settings relating to screen display.
NOTE
Settable items differ depending on settings in “Sensor setup” and “Measurement setup.”
16.7.1 Main display
Three measurement values can be set to display on the Main display as a primary value (1st
line), a second value (2nd line) and a third value (3rd line) respectively.
On the “Additional text”, a text of up to 12 alphanumeric characters can be assigned to each
measurement value.
Additional texts are displayed on the Main display, and are useful for identifying measurements.
In some cases, not all 12 characters can be displayed due to the letters; check the texts
displayed on the Main display after setting. If a part of the text is missing, adjust the number of
characters.
