Introduction
LXT-280
Teledyne Analytical Instruments
4
HORIZONTAL LEFT/RIGHT (◄/►) Arrow Keys
• The right and left arrows are used to enter the calibrate mode.
To enter the calibrate mode, magnetically activate the right
horizontal arrow key. Once in the calibrate mode, the cursor
can be positioned by magnetically activating the right or the
left horizontal arrow key. To exit the calibrate mode,
magnetically activate left horizontal arrow key until the
cursor is all the way to the left.
• These keys also move the cursor horizontally.
1.5 Model Identification
The LXT-280 Transmitter is a 24VDC unit. The instrument is
configured at the factory for the customer’s application and so there are
many different model designators.
The following codes will help in identifying a specific instrument
configuration.
Base Model:
LXT-280
