1. MODELS L C I 1 0 8 - 1 x & L C I 1 0 8 J - 1 x
The LCI108-2x & LCI108J-2x models are small format, 3 ¾ digit instruments designed for temperature measurement with an input stage prepared for connection of Pt100 sensors with three wires. The difference between both models is the size of the digits of the display. Model LCI108J-2x provides 20mm-high digits which makes it easy readable at long distances. In this manual both models are referred with the generic name of LCI108-2x & LCI108J-2x.
The basic instrument is a soldered assembly composed of the main board, and the display and keyboard module. Optionally, it can be equipped with a 2-relay control output card (LCIA-01). This option provides an output connector at the rear of the meter, status LED’s visible from the front and specific programming routines which are enabled automatically once the card is installed. The outputs are isolated from signal input and from supply.
Software configuration allows selection of reading units (Celsius or Fahrenheit) and resolution (degrees or tenths of degree).
