GENERAL DESCRIPTION
The Large Display is a versatile display available as a strain gage meter with
scaling, serial communications and dual relay outputs. The 5 digit displays are
available in either 2.25" or 4" high red LED digits with adjustable display
intensities. The 2.25" high models are readable up to 130 feet. The 4" high
models are readable up to 180 feet. Both versions are constructed of a Type 4X/
IP65 enclosure in light weight aluminum.
All models also come with dual Form C relay outputs and RS232 / RS485
serial communications.
The Crimson software is a Windows based program that allows configuration
of the LD meter from a PC. Crimson offers standard drop-down menu
commands, that make it easy to program the meter. The meter’s program can
then be saved in a PC file for future use. Crimson software can be downloaded
at www.redlion.net.
