Barcode Reader Implementation
The Barcode Reader Module is a LED based line scanner making it totally safe to operate.
The reader is easily attached to the device shoe mounted on the front of the instrument and connected to the front con-
nector.
The Barcode Reader function is activated when the TAG option has been enabled in the menu.
When enabled, the tag reader is checked every time the instrument is turned on; if the function is on and the reader has
been detached the user is asked to disable the TAG reader function.
The reader is activated prior to every measurement on the first trigger action. When the tag has been read, the tag code
is displayed and the next trigger action will execute the measurement.
If the mean calculation function is on, the reader will only be activated prior to the first measurement. This makes it pos-
sible to do multipoint measurements without the need to read the tag for each measurement.
To guide the aiming process the scanner LED’s are pulsed on and off until the bar code has been read.
