14.3 Analog Output
This output can be used for chart recorders, oscilloscopes, data acquisition systems, or any other
compatible devices with analog inputs. The output produces ±1 volt at full scale of the instrument. The
polarity of the signal is positive for compression and negative for tension.
14.4 DATA Key Functions
The DATA key can be configured to perform several functions. To configure the DATA key, select DATA
Key from the menu. The display appears as follows:
Selection
Function when pressing DATA
RS232/USB Output
Outputs data via the serial and USB ports
Mitutoyo Output
Outputs data via Mitutoyo (Digimatic)
Memory Storage
Stores a reading to memory (refer to the Memory section for details)
Auto Zero
Automatically zero the reading as if the ZERO key has been pressed after the
reading is output and/or it is stored in memory.
Auto Zero Delay
The amount of time before the auto-zero occurs, in seconds: 1 – 10 seconds in 1
second increments, and 10 – 60 seconds in 5 second increments.
Any combination of the above functions may be selected.
