LAL
Low Alarm. Units with this feature can sound an alarm when they sense that a user-defined
low temperature has been reached.
Laser
Single or dual lasers are used in some units for aiming and/or locating the optimum
temperature measurement point.
LOC
Location. Units with the data-logging feature store data in numbered locations, which can be
recalled and reviewed on the display when necessary.
Loop
A cycle of operations within a selected mode. For example, the RUN Loop cycles through
standard running operations; the LOG Loop cycles through data logging operations; and the
RECALL Loop cycles through stored operations and displays the data.
Micron (or µm)
10
-6
meters (m), or 0.000001 m.
Minimum spot size
The smallest spot an instrument can accurately measure.
Mode
Modes are various user-selectable operations within Loops.
NETD
Noise Equivalent Temperature Difference. Peak to peak system electrical noise normally
measured at the output (display or analog) expressed in °F or °C.
NIST Traceability
Calibration in accordance with and against standards traceable to NIST (National Institute of
Standards and Technology, USA). Traceability to NIST is a means of ensuring that reference
standards remain valid and their calibration remains current.
